“You have to be able to empathize, process it and then perhaps move on, but you have to feel. If you stop feeling, then you shouldn’t be doing this.”
— Dr. Gernsheimer
What is your proudest achievement?

It has been a privilege to care for my patients and invest in them my knowledge, my energy and my compassion. I’m proud of contributing to a new way of understanding the pathophysiology of autoimmune thrombocytopenia in the late 1980s, which led to developing new treatments and later working on clinical trials with those new therapies. My work with patients with blood disorders has led to innovations in transfusion therapy and prevention of bleeding.

What is your approach to patient care?

We all go into medicine because we want to cure diseases and save lives. Sometimes, it’s just as important to know how to help someone walk a path during difficult times. My patients can ask hard questions. I had a patient who had had multiple miscarriages and wanted more than anything to have a second child. She asked me, “How am I ever going to get through this?” and for a question like that, I honestly don’t always have an answer. However, I will always help my patients find a path to move forward — whatever the outcome is going to be.

Provider background

Specialties and clinical expertise: Hematologic malignancies, non-malignant hematology

Idiopathic thrombocytopenic purpura (ITP)

During my internal medicine residency, a patient was admitted with a severe autoimmune disorder that really caught my attention. The pathophysiology, the questions around therapy, the laboratory work-up — everything about her case was interesting to me. She actually had ITP, and I was fascinated, not realizing at the time that I was going to develop an expertise in it.


My team and I currently have a grant from the National Heart, Lung, and Blood Institute (NHLBI) to evaluate whether we can decrease bleeding in patients undergoing transplant or chemotherapy who are thrombocytopenic (a condition that means you have a low blood platelet count). We are testing different ways to transfuse patients to decrease their risk of bleeding.

Blood disorders

I care for patients with blood disorders including ITP, thrombocytopenia, anemia and excessive bleeding and clotting. I am involved in research related to these diseases, and I also teach UW medical students, residents and fellows in hematology. Teaching is a big part of my life, and I love it.

Clinical trials

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

Many of our SCCA 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.
