Dr. PJ Utz
Principal Investigator

Paul J. Utz M.D.

P.J. Utz joined the Stanford faculty in 1999 and was promoted to Professor of Medicine in 2013. P.J. was born and raised in the Pocono Mountains near Scranton, PA. In 1986, he earned his Bachelor's Degree in Biology from King's College in Wilkes-Barre, PA, with minors in English and Chemistry. While earning his M.D. degree in 1991 from Stanford University School of Medicine, he co-discovered the transcription factor Nuclear Factor of Activated T Cells (NFAT) with J.P. Shaw in Dr. Gerald Crabtree's laboratory. As noted on Dr. Crabtree's website, P.J. incorrectly named the transcription factor (it is not Nuclear, and it is not specific for Activated T Cells). P.J. completed his internal medicine residency, rheumatology fellowship, and post-doctoral training at Brigham and Women's Hospital in Boston prior to joining the Harvard Medical School Faculty in 1996. He left Dr. Paul Anderson's lab in 1999, and his lab at Stanford began experiments in the Spring of 2000.

P.J. has expertise in the study of autoantibodies and autoantigens, apoptosis signaling pathways, animal models of autoimmunity, proteomics and microfluidics. Members of his laboratory are developing several cutting-edge proteomics technologies for immunological applications, including multiplex autoantigen microarrays and EpiTOF. The Utz lab also studies vaccines for autoimmunity, influenza, SARS-CoV-2, and tuberculosis. Professor Utz is a member of the Scientific Advisory Boards of several biotechnology companies, and actively consults with many companies.

Dr. Utz serves as Associate Dean for Medical Student Research where he oversees the Berg Scholars Program, MD-only physician scientist programs, and other medical student research programs. He is director emeritus of the Stanford Medical Scientist Training Program and Founder and Faculty Director of the SIMR Summer High School Research Program which celebrated its 20th anniversary in summer 2019. SIMR students work in biomedical research labs on Stanford campus for 8 weeks. To date, SIMR has trained almost 1,000 high school students. He is also Co-Founder of the Physician Scientist Support Foundation whose goal is to save the “Endangered Physician Scientist,” described in a New England Journal of Medicine article in July 2019.

When not in the lab, P.J. spends most of his free time as an empty-nester with his wife. He enjoys travel, golf, hiking, biking, laying on the beach, watching Warriors and Stanford women’s basketball, and performing ANY non-grant writing activities whatsoever.

Rizwan Ahmed
Senior Scientist

Rizwan Ahmed

Rizwan Ahmed was born in “Rauni” (a small village located near Kannauj city) and grew up in Unnao city in India. He earned his Master’s degree in Molecular Biology and Biotechnology from Tezpur Central University, India. He then went on to do doctoral degree in Biotechnology at the CSIR-Central Drug Research Institute, India, where his research mainly focused in investigating the role of immune cells in disease pathologies. He then moved to Johns Hopkins University, U.S.A for his postdoctoral studies, where he made a paradigm shifting discovery of a previously unknown new lymphocyte (DE cells) that has been shown as key mediators in activating the self-reactive immune cells in autoimmune diseases, specifically, in Type 1 diabetes. Moving forward, he joined Dr. Utz research team as a “Senior Scientist” and interested in understanding the underlying mechanisms responsible for autoimmune pathologies and focusing on designing and developing novel “off-the-self” recombinant immunotherapeutic that can be used in clinical studies to cure the diseases. In spare time, he likes reading, listening to music and channeling his imagination through graphic illustration and architectural design. He loves spending time with family and friends.

Resident

Tyler Prestwood, M.D., Ph.D.

Tyler grew up in rural Northen California and earned his bacghelor's degree in Bioengineering at UC San Diego. After returning from a study abroad program in Brazil, he started working in a viral immunology lab studying dengue virus. He then complete his MD and PhD training at Stanford University School of Medicine studying cancer immunology. He is currently a research track resident at Stanford in the Psychiatry program. His interests involve investigating the serum antibody milieu in patients affected by various illnesses with post-infectious/infection-related compoents including PANS, schizophrenia and post-acute dequelae of COVID. 

Muge
Postdoctoral Scholar

Muge Kalaycioglu

Muge was born and raised in Istanbul, Turkey, where she earned her MD degree. Since 2023, she has been working as a postdoctoral scholar in the lab, focusing on investigating antibody responses in infectious and autoimmune diseases. Muge aspires to pursue her medical training in the U.S. and aims to become a clinical investigator and educator. A fun fact about her is that she had five cats while living in Turkey. She also used to compete in ping pong and handball and enjoysplaying any team sport.

Physician

Katherine Konvinse, M.D., Ph.D.

Katherine grew up in rural New York State and earned her bachelor’s degree in Biological Sciences at Cornell University. She then moved to Nashville, Tennessee and completed her MD and PhD training at Vanderbilt University School of Medicine. She is now a resident physician in the Stanford Pediatric Residency Research Track Program. Her current research in the Utz lab focuses on characterizing the serum antibody responses in pediatric patients exposed to viral infections including COVID-19 and respiratory syncytial virus (RSV). When not in lab or caring for patients, Katherine enjoys spending time outside in the beautiful Bay Area with her husband and young son.
