Rheumatology Fellows Class of 2021


Rebecca Blank, MD, PhD

Dr. Blank, a native New Yorker, attended the University of Pennsylvania where she majored in biology and psychiatry. She did summer research with Dan Kessler (noggin expression in Xenopus) and at NYU Langone with Alan B. Frey (NOD mice and their cytokines). She moved west to the University of California, San Francisco, for PhD training in immunology, studying the relationship between the host immune response and Schistosoma mansoni infection. After postdoctoral training in the lab of Yasmine Belkaid, PhD, at the National Institute of Allergy and Infectious Diseases (studying regulatory T cells in gut lymphoid tissue), she spent time as a Science and Technology Policy Fellow at the American Association for the Advancement of Science, and as a scientific program manager for a Gates Foundation–funded global health project on malnutrition and diarrheal disease at the National Institutes of Health (NIH). Dr. Blank then matriculated at Mount Sinai School of Medicine where she received an Infectious Diseases Society of America Foundation Medical Student Scholarship and directed the student ethics seminar. Dr. Blank then moved on to residency at Cornell University, where she has been doing clinical research with Jessica Gordon, MD, on scleroderma. For fun, Dr. Blank likes running in Central Park and spending time in her kitchen experimenting with new recipes.

Before applying to medical school, she took part in several volunteer efforts, including at the Arlington Free Clinic and working with refugees at the International Rescue Committee. She then moved to Columbus, Ohio, to attend medical school at Ohio State University. As a medical student, Dr. Haj-Ali received the Noor Community Clinic Award and the Helmick Scholarship. She was able to pursue her passion for global health during medical school by participating in a global health elective in Thailand and working with underserved communities in rural Morocco. Dr. Haj-Ali returned to the D.C. area for her residency in internal medicine at George Washington University. As a resident, she worked with Victoria Shanmugam, MD, to study whether scleroderma patients with negative immunofluorescence antinuclear antibody had different characteristics and prognosis compared with scleroderma patients with positive immunofluorescence antinuclear antibody. Her personal interests include traveling, experiencing ethnic cuisines, and watching documentaries.


Ben Plotz, MD

Dr. Plotz is a native New Yorker—actually, a native Brooklynite. He attended college at the University of Chicago, where he majored in history, philosophy, and social studies of science and medicine. He moved on to medical school at SUNY Downstate Health Sciences University and then to residency at George Washington University. While in college, he conducted pediatric cancer research with Kenan Onel, MD, PhD, looking at a particular P53 polymorphism and its role in melanoma cell lines. He also received experience in a human research project, recruiting subjects for the development of a pediatric cancer genetic biobank. Between college and medical school, Dr. Plotz spent a year in the laboratory of Steve Goldring, MD, at the Hospital for Special Surgery, studying osteoclastogenesis in mouse and cell culture models. During medical school, Dr. Plotz worked with Ellen Ginzler, MD, in a study examining the genotypic basis for end-stage renal disease in lupus. During residency, Dr. Plotz worked at the NIH with Andrew Mammen, MD, PhD, in the Muscle Disease Unit, on a project identifying anticortactin as a myositis-associated antibody.
