“When a patient comes to me for lymphoma treatment, I want to know every single detail about their medical conditions, but also to learn their perspective as a person outside their diagnosis.”

— Dr. Di

What motivates you as a researcher?

My goal is to improve outcomes for patients with lymphoma and chronic lymphocytic leukemia. To help achieve this, my research has been focused on two aspects. 

The first one is to design and conduct clinical trials to examine whether a new therapy for lymphoma is effective. This type of research allows us to bring new therapies to patients, especially those who are actively searching for new treatments. 

My second focus is to identify barriers or challenges in the management of lymphoma outside clinical trials and to find possible solutions. Sometimes therapies do not work as well in daily practice as in clinical trials. It is very important for us to better understand the potential explanations of such differences.

What brought you to treating patients with lymphoma?

My interest in blood cancer/lymphoma began when I was a medical student. I found it very rewarding to take care of patients and to witness people eventually returning to the lives they led prior to their cancer diagnosis. Later, I realized that it was not all satisfying like this, and challenges did arise. These challenges never made me regret my career choice; instead, they have strongly motivated me to pursue meaningful research to improve outcomes.

Provider Background

Area of Clinical Practice
Lymphoma, chronic lymphocytic leukemia

I am a physician who sees patients at the South Lake Union Clinic.

The diagnosis and treatment of lymphoma may impact many aspects of life, so it’s important that we focus on each patient’s needs. I work closely with patients to choose the best therapies for them. Treating lymphoma is a unique area that allows me to integrate my passions, interests and skills.

Clinical Trials

We make promising new treatments available to you through studies called clinical trials led by Fred Hutch physicians. Many of these trials at Fred Hutch have led to FDA-approved treatments and have improved standards of care globally. Together, you and your physician can decide if a study is right for you.

Many of our Fred Hutch physicians conduct ongoing research to improve standards of patient care. Their work is evaluated by other physicians and selected for publication to the United States National Library of Medicine, the largest medical library in the world.
