Biography
He serves on the OMERACT 2022 SLE Working Group, an international collaborative effort that is aiming to revisit and update the core set domain of outcome measures to be assessed in randomized controlled trials and longitudinal observational studies in SLE. He has served as a principal investigator on clinical trials in SLE, and is involved in the Lupus Clinical Investigators Network (LuCIN). He has an ongoing interest in clinical/translational team science approaches that answer important questions relevant to lupus. He works closely with Dr. Julia Simard and other research collaborators on various projects, including studying pregnancy outcomes in SLE, the role of cognitive bias in the evaluation of lupus/other autoimmune conditions, and work centered around COVID-19 and autoimmunity. In addition, he serves as the Faculty Lead for the Division of Immunology and Rheumatology’s Clinical Research Unit (CRU) at Stanford University School of Medicine.
He is the Associate Program Director for the Rheumatology Fellowship program at Stanford. From a teaching standpoint, he is actively involved in the education of medical students, PA students, residents, and rheumatology fellows on topics related to rheumatology including SLE. He is also engaged in educational outreach for patients with SLE through several forums including the Lupus Foundation of Northern California.
