Siddhartha Jaiswal
Associate Professor of Pathology
Current Research and Scholarly InterestsWe identified a common disorder of aging called clonal hematopoiesis of indeterminate potential (CHIP). CHIP occurs due to certain somatic mutations in blood stem cells and represents a precursor state for blood cancer, but is also associated with increased risk of cardiovascular disease and death. We hope to understand more about the biology and clinical implications of CHIP using human and model system studies.

Sajid Jalil
Clinical Associate Professor, Medicine - Gastroenterology & Hepatology
BioDr. Jalil is a board-certified, fellowship-trained transplant hepatologist (liver doctor) and gastroenterologist at the Stanford Health Care Digestive Health Center in San Jose, California. He is also a clinical associate professor in the Department of Medicine, Division of Gastroenterology and Hepatology, at Stanford University School of Medicine.
Dr. Jalil has extensive experience helping patients with a range of liver- and digestion-related conditions. He specializes in liver transplantation, and his other clinical interests include all forms of hepatitis, cirrhosis of the liver, fatty liver disease, polycystic liver disease, and primary sclerosing cholangitis (swelling and scarring of the bile ducts). He has also volunteered in initiatives to offer free colonoscopy and hepatitis B screenings to underserved ethnic populations.
His research interests include improving mental health by enhancing treatment access for patients with alcohol use disorder causing alcoholic liver disease. He has also studied swallowing problems, liver disease in pregnancy, living liver donation, and the use of artificial intelligence in treating nonalcoholic fatty liver disease and viral hepatitis. In addition, Dr. Jalil wrote a chapter on bile secretion and cholestasis (diminished bile flow) for the fifth edition of Yamada’s Textbook of Gastroenterology.
Dr. Jalil has published in numerous peer-reviewed journals, including World Journal of Hepatology, Liver Transplantation, and the Journal of Clinical Gastroenterology. Additionally, he has served as a reviewer for Pancreatology and as an abstract reviewer for the American Gastroenterological Association (AGA) and the Ohio Chapter of the American College of Physicians. He has presented his research at meetings and conferences worldwide on a range of topics, including the timing of pregnancy after liver transplantation.
Dr. Jalil is an AGA fellow and a member of the American Association for the Study of Liver Diseases, American College of Gastroenterology, and American Society for Gastrointestinal Endoscopy. -
Mehrnaz Nicole Jamali MD
Clinical Associate Professor, Medicine
BioDr. M. Nicole Jamali focus has been in leadership, scientific innovation and streamlining business ventures. Over the past 20 years since graduation from Stanford Internal Medicine Residency, she has held National Positions in AMA as Western Caucus Chair and Appointee to Joint Commission Board. She was reelected to Board of Joint Commission three terms for total of 9 years. She helped rewrite multiple TJC Standards including creation of the Stroke Center of excellence standards and annual "new ideas section of the board". At AMA she authored and passed multiple House rules on variety of subjects affecting thousands of providers and healthcare centers. Her experiences in private practice, group practice, Hospitalist, Insurance Directorship lead to multiple innovative projects including first e-prescription covering both meds and DME in 1999 titled eRemedy,. She then created the first wrong site surgery device which was patented. This project lead to creation of first Transplant App called TPOD which was then simplified to TAPP. It was beta tested in USC and perfected in UCSF Transplant.
Her work with various Insurance companies resulted in streamlined programs and teaching modules improving patient access to health care and millions of dollars in hospital savings of unnecessary admissions.
Her work in creation and streamlining and connecting with local Primary Care providers resulted in rapid expansion of the Hospitalist program of local Hospital by 300%
She is currently interested in Haptic and AI technologies in Medicine and providing 24/7 care to our veterans in remote locations or even the battlefield.
She is currently Clinical Associated Professor and the lead Hospitalist in the new Stanford Cardiovascular Hospitalist Program and enjoys the daily interaction with patients . She truly believes that her mission in life is to be at the bedside of ill patients. She treats them as one of her own family. It is not atypical for her to hand out her personal phone number to make sure they feel safe even when discharged. -
Michelle L. James
Associate Professor of Radiology (Molecular Imaging Program at Stanford) and of Neurology and Neurological Sciences (Neurology Research)
Current Research and Scholarly InterestsThe primary aim of my lab is to improve the diagnosis and treatment of brain diseases by developing translational molecular imaging agents for visualizing neuroimmune interactions underlying conditions such as Alzheimer’s disease, multiple sclerosis, and stroke.

Safwan Jaradeh, MD
Professor of Neurology and Neurological Sciences (Adult Neurology) and, by courtesy, of Psychiatry and Behavioral Sciences
Current Research and Scholarly InterestsClinical interests include autonomic disorders, small fiber neuropathies and the development of effective methods of testing and treating these disorders. Prior work has focused on small fiber painful and autonomic neuropathies; syndromes of orthostatic intolerance and syncope; gastrointestinal motility dysfunction; cyclic vomiting; protacted Gastroesophageal Reflux; non-allergic rhinitis syndromes; and the relationship between the autonomic nervous system and normal or abnormal sleep. Additional areas of interest include the neurology of phonation and swallowing disorders, and peripheral nerve injury and repair.

Ted Jardetzky
Professor of Structural Biology
On Partial Leave from 12/01/2025 To 02/28/2027Current Research and Scholarly InterestsThe Jardetzky laboratory is studying the structures and mechanisms of macromolecular complexes important in viral pathogenesis, allergic hypersensitivities and the regulation of cellular growth and differentiation, with an interest in uncovering novel conceptual approaches to intervening in disease processes. Ongoing research projects include studies of paramyxovirus and herpesvirus entry mechanisms, IgE-receptor structure and function and TGF-beta ligand signaling pathways.

Daniel Jarosz
Senior Associate Dean, Basic Science, Professor of Chemical and Systems Biology and of Developmental Biology
Current Research and Scholarly InterestsMy laboratory studies conformational switches in evolution, disease, and development. We focus on how molecular chaperones, proteins that help other biomolecules to fold, affect the phenotypic output of genetic variation. To do so we combine classical biochemistry and genetics with systems-level approaches. Ultimately we seek to understand how homeostatic mechanisms influence the acquisition of biological novelty and identify means of manipulating them for therapeutic and biosynthetic benefit.
