Jennifer A McNab
Associate Professor (Research) of Radiology (Radiological Sciences Laboratory)
Current Research and Scholarly InterestsMy research is focused on developing magnetic resonance imaging (MRI) methods that probe brain tissue microstructure. This requires new MRI contrast mechanisms, strategic encoding and reconstruction schemes, physiological monitoring, brain tissue modeling and validation. Applications of these methods include neuronavigation, neurosurgical planning and the development of improved biomarkers for brain development, degeneration, disease and injury.

Rishi Mediratta
Clinical Associate Professor, Pediatrics
Current Research and Scholarly InterestsI have developed a new promising neonatal mortality prediction score at the University of Gondar Neonatal Intensive Care Unit (NICU) in Gondar, Ethiopia. The score predicts approximately 84% of neonatal deaths in the NICU using clinical variables. I have a dataset over 800 NICU admissions in Gondar. I am recruiting scholars who are interested in conducting clinical and epidemiological research to validate, refine, and implement the mortality score to reduce neonatal mortality in Ethiopia.

Eric Meffre
Professor of Medicine (Immunology and Rheumatology)
BioDr. Meffre obtained his PhD in Immunology from the Université d’Aix-Marseille in France before he moved to the USA as a postdoc fellow in the laboratory of Dr. Michel Nussenzweig at The Rockefeller University in New York City. He became an assistant professor at Cornell University in 2003 before being recruited at Yale University as associate professor in 2009. He was tenured at Yale in 2014 before he joined the Department of Medicine/Division of Immunology and Rheumatology at Stanford University as a tenured full professor in 2022.
Dr. Meffre’s work focuses on the etiology of autoimmune syndromes and the roles played by B cells in these diseases. His group characterized the abnormal selection of developing autoreactive B cells in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), type 1 diabetes (T1D), multiple sclerosis (MS) and Sjögren’s syndrome, resulting in large numbers of autoreactive naïve B cells accumulating in the patient’s blood. Hence, these autoreactive B cells may present self-antigens to T cells and initiate autoimmune diseases. These early B cell tolerance defects are likely primary to these autoimmune diseases and may result from genetic factors such as the 1858T PTPN22 allele that segregates with RA, SLE and T1D and correlate with an impaired removal of developing autoreactive B cells.
His research goals also consist in characterizing the molecules and pathways involved in the establishment of B cell tolerance and the removal of developing autoreactive B cells generated by random V(D)J recombination through the investigation of rare patients with primary immunodeficiency (PID) enrolled through an international network. Alteration of B cell receptor (BCR) or Toll-like receptor (TLR) signaling in PID patients results in a defective central B cell tolerance and a failure to counterselect developing autoreactive B cells in the bone marrow. In contrast, functional and suppressive regulatory T cells play a key role in preventing the accumulation of autoreactive clones in the mature naïve B cell compartment. The recent development of humanized mouse models recapitulating early B cell tolerance checkpoints and their defects in autoimmune settings allow further in-depth investigation of tolerance mechanisms and the development of novel approaches to restore defective central and peripheral B cell tolerance checkpoints and thwart autoimmunity. -

Arnav Mehta, MD, PhD
Adjunct Clinical Assistant Professor, Medicine - Oncology
BioDr. Mehta is a board-certified, fellowship-trained medical oncologist at the Stanford Medicine Cancer Center. He is also an adjunct clinical assistant professor in the gastrointestinal (GI) oncology group of the Department of Medicine, Division of Oncology at Stanford University School of Medicine.
Dr. Mehta specializes in gastrointestinal cancer, with a particular focus on pancreatic and gastric cancers. He also treats colorectal cancers. His treatment specialties include immunotherapy — helping a patient’s immune system fight cancer — and targeted therapies, which send cancer-fighting drugs to specific cancer cell molecules.
His research interests include understanding why GI cancers resist treatments and identifying new ways to treat these tumors. In particular, he is interested in GI tumor immunology, which focuses on directing a person’s immune system to help destroy cancer cells. He also has a special interest in tumor plasticity, which represents the ability of a tumor cell to evolve and develop resistance to therapies.
Dr. Mehta has earned research awards and grants from organizations including the American Association for Cancer Research (AACR), American Society of Clinical Oncology (ASCO), American Society of Hematology (ASH), and the National Institutes of Health.
Dr. Mehta has published in many peer-reviewed journals, including Nature, Nature Genetics, Nature Immunology, Nature Medicine, Nature Cancer, Cancer Discovery and Immunity. He has written book chapters on subjects including esophageal and gastric cancer. He has also presented his research on topics including tumor immunology and pancreatic cancer at dozens of symposia and meetings around the country.
