intmedrheumknightteamyalavarthi Srilakshmi (Sri) Yalavarthi, MS
Sri Yalavarthi, MS has worked at the University of Michigan for over 18 years and joined the lab in 2013. Apart from general lab maintenance, Sri's current work primarily focuses on the role of anti-NET antibodies as potential biomarkers for disease severity in auto immune diseases such as APS. She is also interested in investigating any potential connection between anti-NET antibodies and disease progression in COVID-19 patients. Outside the lab, Sri enjoys gardening and wishes that Michigan would have long summers. She also loves to travel to new places with her family and try out new cuisines.
intmedrheumknightteamali Ramadan Ali, PhD
Dr. Ramadan Ali completed his bachelor’s degree in Pharmaceutical Sciences from the University of Toledo, Ohio where he also received his PhD degree in Medicinal Chemistry. He joined the Michigan Medicine Division of Rheumatology in 2017 as a postdoctoral fellow. Dr. Ali's research focuses on adenosine receptors as potential therapeutic targets in APS. He is also interested in natural medicine, specifically the anti-inflammatory effects of ginger-derived compounds in the context of lupus, APS, and other inflammatory diseases. In his off-time, Dr. Ali loves to spend quality time with his family.
intmedrheumknightteammadison Jacqueline Madison, MD
Dr. Jacqueline Madison, a Clinical Assistant Professor in Adult and Pediatric Rheumatology, joined the research team in 2019. Dr. Madison is interested in the study of APS, with a particular concentration in pediatric APS. She also contributes to the study of thrombosis and antiphospholipid antibodies in COVID-19 patients. Dr. Madison graduated from Yale University with bachelor’s degrees in Biology and Anthropology. She received her MD and completed both a combined Internal Medicine-Pediatrics residency and fellowship at the University of Michigan. Dr. Madison enjoys exploring the outdoors, traveling, and spending time with her family and labradoodle.
ajay Ajay Tambralli, MD
Dr. Ajay Tambralli, Clinical Assistant Professor of Internal Medicine and Pediatrics, focuses his research on the role of neutrophil metabolism in the pathogenesis of APS. Dr. Tambralli received his medical degree from the University of Alabama at Birmingham in Birmingham, Alabama. He then completed his residency at the University of Rochester in Rochester, New York and a combined Internal Medicine-Pediatrics fellowship at Michigan Medicine. Listen to Dr. Tambralli present his research "Neutrophil Glucose Flux as a Therapeutic Target in Antiphospholipid Syndrome."

Postdoctoral Fellows
intmedrheumknightteamliu Chao Liu, PhD
Dr. Chao Liu is a postdoctoral research fellow who joined the team in 2020. Dr. Liu works primarily on the study of renin-angiotensin system regulation on neutrophils, as well as a number of other studies involving diabetes and COVID-19. He is a 2015 graduate of Nanjing Medical University with a PhD degree in cardiovascular pharmacology. In his free time, Dr. Liu enjoys exercise and traveling.
intmedrheumknightteamnaveen Somanathapura K. NaveenKumar, PhD
Dr. Somanathapura K. NaveenKumar is a postdoctoral research fellow who joined the lab in December 2021. Dr. NaveenKumar's research interests include the roles of platelets and neutrophils in the pathogenesis of thromboinflammation. He received his PhD in Biochemistry (2018) from the University of Mysore, India and then trained at the Indian Institute of Science (Prof. G. Mugesh Lab) as a postdoctoral fellow (2018-21). Dr. NaveenKumar is currently investigating the role of ectonucleotidases and adenosine receptors on platelets as potential avenues for inhibiting arterial and venous thrombosis in APS. He is also interested in evaluating different cell death pathways in APS neutrophils.
