The Viral Pathogenesis and Evolution Training Program (formerly the Viral Pathogenesis Training Program) links students from various graduate programs who are currently training in virology laboratories in Seattle. The program brings together laboratories at Fred Hutch and the University of Washington with the goal of drawing on the rich history of viral research at these institutions to form a unique training opportunity for Seattle-area graduate students.
Funds are available for pre-doctoral trainees interested in viral pathogenesis and evolution research. One or two years of funding is available, with preference given for two years of funding for earlier stage students as discussed below. The training program will also cover a portion of tuition. The scope of the submitted proposal should include a two-year research plan, unless the applicant specifically requests only one year of funding.
Please note, this training grant is managed by the UW and thus pay and benefits will be through the UW.
In addition to the curriculum required by the student’s graduate program, students who are funded by the VPETG will be required to take courses that will enhance their training in viral pathogenesis and evolution research, including one course in viral pathogenesis/virology (MCB532 or MICRO 540) and one elective course in either computation biology and immunology (MCB 517 or IMMUN 532). Finally, because writing is an important component of academic scientists' training, VPETP trainees will receive opportunities for additional training in this area.
First, the applicant should send items 1-3 in a single PDF format to the Training Grant Administrator, Shama Sammant. File title: "ApplicantLastName_VPETP2019.pdf"
1. The Applicant Form
2. CV, Resume, or Biosketch providing details of your academic training to-date, any relevant research/work experience, and a copy of your current academic transcript (unofficial OK).
3. Research Proposal. The proposal must be applicable to viral pathogenesis, viral evolution, or computational studies of viruses and you must explain the relevance in the proposal. Please include an explanation of how your research reflects the training grant's goals. This may be included in the Abstract, Background and Significance, or a paragraph at the end of the proposal. The scope of the submitted proposal should include a two-year research plan unless the applicant specifically requests only one year of funding. Proposal guidelines: The proposal should not exceed 2 pages (single spaced, Arial font, 11 pt., including figures). References may be on additional pages. Follow the general NIH format to include Specific Aims, Significance, Innnovation, and Approach.
Second, the applicant’s mentor and the two individuals (non-mentors) writing the applicant’s letters of recommendations should send items 4-5 directly to the Training Grant Administrator, Shama Samant.
4. Mentor Summary Form [hyperlink to mentor summary form asset]. This form should be filled out by your mentor. In past years we have asked for more traditional letters. However, all the mentor letters said their student was one of the best they have ever seen and they should be funded, which was not helpful to the review committee. It is our hope, that the mentor summary form will be a more informative evaluation of each trainee. Since the success and future funding of the training grant depends on the quality of the students it supports, the review committee would appreciate an honest and realistic summary of the student. Please have your mentor send their summary directly to the Training Grant Administrator, Shama Samant.
Letters of Recommendation. Request letters from 2 individuals who are not your mentor. Please have your recommenders send their letters directly to the Training Grant Administrator, Shama Samant .
The Avgousti lab is focused on the mechanisms by which viruses hijack chromatin. Studies in her group focus on DNA viruses, which are packaged with small basic proteins that can resemble histones and incorporate histones onto their genomes during infection. The lab uses a multidisciplinary approach including biochemical, molecular biology, cell biology and biophysics to decipher virus-host interactions at the epigenetic level. Trainees in her lab engage in studies of virus-host interactions, proteomics, genome-wide analyses, and viral pathogenesis.
Collaborators on the TG: Adam Geballe, Michael Lagunoff, Jason Smith
Dr. Avgousti will be mentored until the student(s) who are currently being trained in the lab obtain their PhD.
The Bedford lab focuses on phylodynamic analysis of pathogen sequence data with an intent of making inferences that are actionable to public health. His primary research goal is to develop mathematical and statistical methods to integrate infectious disease sequence data into evolutionary and epidemiological models. His work integrates population genetics, phylogenetics and epidemiological modeling to understand virus evolution and transmission patterns. This work has a strong statistical and computational basis, using sequence data to arrive at an understanding of underlying processes. By analyzing genetic relationships among viral samples, phylogenetic trees can be constructed that describe the evolutionary history of the viral population and from these trees, patterns of infection can be inferred. Such analyses may offer substantial public health benefit through improvements to vaccine strain selection and outbreak response. Trainee’s in the Bedford lab learn computational and are exposed to public health strategies and they often collaborate closely with other groups on the training grant.

Dr. Bedford will be mentored until the student(s) who are currently being trained in the lab obtain their PhD.
The Bloom lab uses a mix of experimental and computational approaches to study the evolution of viruses. Much of their work focuses on influenza virus, although they also have projects on HIV, Zika virus, and RSV. One major focus of the group is to use high-throughput experiments to map the effects of large numbers of mutations on the function and antigenicity of viral proteins, and then relate these maps to viral evolution in nature. Another major focus of the group is to use deep-sequencing to characterize the diversity of viral infections of humans. Finally, the group is developing new single-cell sequencing approaches to study viral infection. Trainee’s in the Bloom lab learn a mix of computational and experimental biology, and often collaborate closely with other groups on the training grant.

They do this by studying the evolution and function of host antiviral genes. Their goal is to determine how HIV adapted to humans, and how ancient viral infections influenced the susceptibility or resistance of humans to modern lentiviruses. Trainees in his lab engage in studies of gene and virus evolution, virus-host cell interactions, high-throughput genetic screens, and functional studies of viral and host proteins.
Collaborators on the TG: Adam Geballe, Harmit Malik, Erick Matsen, Julie Overbaugh
The Frahm lab studies the influence of HIV sequence diversity on its recognition by cytotoxic T lymphocytes, as well as the factors governing the recognition of sequence variants both in HIV-infected subjects and in vaccine trial participants. Studies of her group focus on how the dynamics between the virus and the host influence virus-specific cellular immune responses and contribute to viral control or lack thereof. These studies include a detailed analysis of immune responses to individual HIV epitopes and their variants, and the complex interplay between these responses and virus escape as it occurs in individuals followed longitudinally from acute infection. More recently, her lab is contributing to understanding cellular immunity to therapeutic HIV vaccines. These studies are done as part of a larger collaborative effort that includes her lab, virologists and clinician scientists. Trainees in her lab engage in studies of viral evolution, virus-host cell interactions, and viral immunology.

Research in the Geballe lab focuses on identifying the factors, dissecting the mechanisms, and understanding the evolutionary pathways used by large DNA viruses, such as cytomegaloviruses and poxviruses, to enable them to replicate efficiently despite host defenses. The lab is interested in the evolutionary “arms race,” between the virus and host cell in which the structure and specificities of the participating genes change with surprising rapidity. Trainees in the lab engage in research aiming to clarify how genes such as TRS1 and IRS1 of human cytomegalovirus genes block the protein kinase R pathway, and how homologous genes in different primate viruses have and can adapt to changes in this and other host defenses.
Collaborators on the TG: Daphne Avgousti, Michael Emerman, Michael Lagunoff, Harmit Malik
The Jerome lab focuses on the chronic and latent phases of virus infections, virus immune evasion mechanisms, and potential curative therapeutic approaches to these infections. His most recent work involves the use of enzymes we classify as rare-cutting endonucleases that can specifically target latent viral DNA for cleavage. Upon cleavage of viral DNA mutations are introduced in viral coding sequences and this results in virus inactivation. This approach may allow precise inactivation of functional viral DNA within infected cell reservoirs and offers the prospect of a cure for HIV, HBV and HSV. Trainees in the lab learn methods relevant to gene therapy approaches for viral infections including current approaches aimed at cure.
Collaborators on the TG: Nicole Frahm, Deobrah Fuller
The Lehman lab studies viral dynamics, viral reservoirs and viral transmission. They conduct molecular virology studies in Kenyan cohorts in collaboration with epidemiologists, biostatisticians and clinician scientists at both the University of Washington and the University of Nairobi. Current studies include modeling long term dynamics of the latent HIV reservoir in Kenyan infants and determining the influence of immune activation and function on HIV reservoir size and decay. In addition, Lehman leads a study to define novel components of the human virome (population of all viruses) that impact infant health and to explore mechanisms by which maternal HIV and ART alters the transmission of the virome from mother to infant. Trainees acquire skills in molecular biology, epidemiology, and statistics and are exposed to interdisciplinary research.
Collaborators on the TG: Julie Overbaugh, Erick Matsen
Dr. Lehman will be mentored until the student(s) who are currently being trained in the lab obtain their PhD.
The Lund lab focuses on elucidating the basic mechanisms of anti-viral immunity and mucosal immunity using both mouse models as well as human tissues. Current projects include defining the roles and modes of action of tissue-resident memory T cells and regulatory T cells during mucosal virus infection, identifying novel mucosal immune correlates of protection from HIV-1 infection, and discovering new genes involved in immune responses to flavivirus infection, including both Zika and West Nile viruses. The goal of these studies is to improve clinical interventions for virus infections of public health importance. Trainees in the lab engage in studies of viral immunity and mucosal immunity.
Collaborators on the TG: Nicole Frahm, Michael Gale, Martin Prlic
The Malik lab is interested in the evolutionary rules that shape host-virus interactions. His lab has dissected the evolutionary history of host-virus interactions between primate genomes and retroviruses (with Emerman lab), poxviruses (with Geballe lab), hepaciviruses (with Gale lab) and orthomyxoviruses (with Emerman lab). These case studies of antiviral genes have revealed many common 'evolutionary rules' about when (how old), where (which protein domains) and how (functional consequences of adaptive changes) host-virus 'arms races' have altered the host and viral proteins involved. His work with the Emerman lab has shown that evolutionary analyses can derive evidence of past viral infections, even those that may not have left imprints in host genomes – a term he coins indirect 'paleovirology'. His lab has discovered that one previously unappreciated form of viral adaptation is via 'gene-accordions' that facilitate acquisition of adaptive alleles. Recent focus in the lab has been on the Mx antiviral proteins, and whether their broad specificity against multiple DNA and RNA viruses incurs fitness tradeoffs. Trainees learn both evolutionary and combinatorial mutagenesis strategies to dissect what constraints act on host immunity.
Collaborators on the TG: Jesse Bloom, Michael Emerman, Adam Geballe, Michael Gale, Denise Galloway, Erick Matsen
The Matsen group develops and apply evolutionary methods for molecular sequence data (i.e. DNA and RNA). They enjoy all facets of computational biology research, from diving deeply into biological questions, to mathematical and statistical analysis, algorithm development, and efficient algorithm implementation. Their recent work has developed new methods to analyze metagenomic, viral, and immune cell sequence data, as well as pursued more abstract methodological questions in evolutionary tree reconstruction. They also work to improve the software environment for computational biologists, both by developing our own open-source tools and contributing to work on larger projects. Trainees learn advanced computational skills relevant to the study of viral and immune system evolution.

The overarching scientific interest of the Strong lab is understanding the molecular mechanisms that functionally differentiate specific versus degenerate or polyspecific protein recognition events. His research focus has been on molecular immunology and vaccinology. They use the tools of structural molecular biology, particularly x-ray crystallography and surface plasmon resonance biomolecular interaction analysis, to study and exploit antibody/antigen interactions including the highly variable HIV Env antigen. Trainees learn basic biochemical and structural methods and are exposed to virology and immunology because the projects are often inherently multi-disciplinary and highly collaborative.
Collaborators on the TG: Denise Galloway
The Subramaniam lab studies mechanisms of mRNA translation in microbial and mammalian cells. Studies in his group focus on identifying kinetic and biophysical constraints on factors mediating translational regulation. These studies utilize genome-wide and computational approaches for identifying how translation is regulated at the initiation, elongation, and termination phases, and are followed by biochemical dissection of the factors involved. Recent work from the group has identified novel sites of translation initiation during influenza infection of human cells. One of these sites were shown to produce functional protein that retains activity. Current efforts are directed towards applying unbiased sequencing-based approaches for uncovering translational regulatory mechanisms during influenza and HIV infection. Trainees in his lab engage in mechanistic studies of viral and host mRNA translation during infection.

The Lagunoff lab is studying how Kaposi’s Sarcoma herpesvirus alters host endothelial cells to cause Kaposi’s Sarcoma, an endothelial cell-based hyperplasia. The lab studies two main areas of KSHV pathogenesis, KSHV alteration of cellular metabolism and KSHV induction of oncogenic signal transduction pathways to activated latently infected endothelial cells. The lab has shown that KSHV latent infection dramatically alters host cell metabolism and that the alterations in host cell metabolism are required for the survival of latently infected cells, providing a novel therapeutic opportunity. Their studies of KSHV activation of endothelial cells have shown that KSHV induces angiogenic phenotypes and endothelial cell differentiation and that latent KSHV infection can lead to proliferation past senescence in specific types of endothelial cells. Trainees in the lab learn virology and cell biology.
Collaborators in the TG: Daphne Avgousti, Adam Geballe, Jason Smith, Joshua Woodward

The Lingappa lab studies mechanisms of HIV genome packaging and capsid assembly. Using biochemical and imaging approaches, her group has identified host ribonucleoprotein complexes that are co-opted by HIV and other retroviruses during packaging and assembly. They also identified two cellular enzymes that facilitate HIV capsid assembly and are present in these host complexes. Their current studies involve investigating the mechanism by which HIV capsid proteins and the HIV genome are recruited to these host complexes. Additionally, they are examining the ancient evolutionary origins of the viral-host interactions critical for generating these complexes. Most recently they have started to utilize antiviral small molecules that target these complexes to gain insight into how these important host complexes function during HIV packaging and assembly. Trainees learn biochemistry and cell biology at the interface of virus/host cell interactions.
The Mullins lab uses molecular, computational, and virus biology techniques to provide insights into the relationship between HIV and its human hosts in an effort to fight the AIDS pandemic. Current work is devoted to identifying components of each viral protein that should be included or excluded in a vaccine through examination of the impact mutations have on viral function and immunogenicity studies. Their work focused on responses against conserved elements of HIV is being tested in human clinical trials in both HIV-infected and uninfected persons. Their long-standing interest in the pathogenesis of HIV infection now centers on means of defining, reducing and eventually eliminating reservoirs of infection in HIV-infected humans. Trainees learn computational approaches to the study of virus infections.
Collaborators on the TG: Nicole Frahm, Deborah Fuller
The Nghiem lab and its multi-disciplinary clinical team focuses on Merkel cell carcinoma (MCC), a UV- and polyomavirus-associated skin cancer that has quadrupled in the past 2 decades. The lab has characterized Merkel polyomavirus-specific T lymphocytes and shown evidence of antigen-specific dysfunction that led them to suggest that PD1 pathway blockade could be beneficial for patients with advanced MCC. Clinical trials of their team have now resulted in PD1 pathway blockade as the new standard of care for MCC, with durable responses for about half of patients with advanced MCC. Trainees learn virology and immunology and also have the opportunity to participate in bench to bedside research.

The Savan lab studies gene regulatory mechanisms that modulate innate immune responses, with a specific focus on exploring the effect of genetic variations in immune genes that affect viral infection. The lab has identified non-coding polymorphisms that strongly associate with susceptibility to HCV and human HIV infections. The lab has also identified new molecular pathways that lead to distinct antiviral responses to type I and III interferons. Savan lab integrates studies on genetic variation and gene-regulatory controls in innate immunity to reveal novel host-pathogen interface. Trainees learn fundamental aspects of the innate immune response to viral infections.
Collaborators on the Training Grant: Michael Gale, Jennifer Hyde, Martin Prlic, Joshua Woodward
The Smith lab studies mucosal immunity to viral infection, with a particular emphasis on the role of enteric alphadefensin antimicrobial peptides in the pathogenesis of gastrointestinal infections. These studies are part of a larger effort to understand the role of epithelial cells in the innate immune response to microbes. Major viruses of interest include adenoviruses and rotaviruses. The lab utilizes molecular virology, traditional cell culture, mouse pathogenesis models, and cutting-edge three-dimensional intestinal epithelial (enteroid) culture models to inform an integrated model of host-pathogen interactions at multiple scales of biology. Projects involve extensive collaboration with scientists both in Seattle and at other major research institutions.

Collaborators on the TG: Daphne Avgousti, Michael Lagunoff
The Sodora lab focuses on three general areas that include factors that influence HIV transmission, preclinical vaccine development to prevent HIV transmission, and factors that contribute to HIV-associated co-morbidities, such as liver disease. The lab recently examined the impact of BCG vaccination in infants and how immune activation elicited by vaccination may affect HIV transmission and disease progression. The Sodora Lab also has an ongoing study to evaluate how oral administration of a pre-clinical HIV vaccine drives key innate immune responses required to drive protective adaptive immunity. In addition, there is also a focus on the mechanisms that drive disease pathogenesis after infection, particularly liver disease. Trainees study the dynamics of bacterial communities as they relate to viral infections.
Collaborators on the TG: Michael Gale, Deborah Fuller
The Veesler lab studies the structure and function of macromolecular complexes involved in viral pathogenesis to provide avenues for creating next-generation subunit vaccines and novel therapeutics. They are using a multidisciplinary approach integrating cryo-EM and X-ray crystallography with biophysics, virology and immunology to obtain multi-scale data ranging from atom to whole-cell. They are especially interested in emerging zoonotic viruses with high-pandemic potential, such as coronaviruses and henipaviruses, since cross-species transmission events pose great challenges for public health. Their work places a special emphasis on the glycoproteins decorating the surface of these human pathogens and that promote entry into host cells. Trainees learn skills in structural biology that inform the biology of viral proteins.
Dr. Veesler will be mentored until the student(s) who are currently being trained in the lab obtain their PhD.
The Woodward laboratory aims to define the molecular mechanisms that affect host pathogen interactions. They are interested in small molecules that shape the physiology and pathogenesis of infectious agents, as well as host derived metabolites that contribute to innate and cell intrinsic immunity. A central focus of the lab is the class of second messengers deemed cyclic dinucleotides. CdNs have emerged as key mediators of infectious responses to both bacterial and viral pathogens, eliciting both inflammatory immune responses and global cellular changes aimed at microbe restriction. Recent characterization of the cGAS signaling pathway is underway to define the cell intrinsic restriction of viral replication elicited by the second messenger cGAMP. Trainees utilize genetic, structure-function and biochemical studies to interrogate the molecular interactions between cdNs and their protein targets, together with tissue culture and murine models of infection and disease to define the biological impact of these interactions.
