Jon-Paul Pepper, MD
Associate Professor of Otolaryngology - Head & Neck Surgery (OHNS)
Current Research and Scholarly InterestsFacial paralysis is a debilitating condition that affects thousands of people. Despite excellent surgical technique, we are currently limited by the regenerative capacity of the body. The mission of our research is to identify new treatments that improve current facial paralysis treatments. We do this by exploring the regenerative cues that the body uses to restore tissue after nerve injury, in particular through pathways of neurogenesis and nerve repair in small mammals.

Jack Percelay
Clinical Professor, Pediatrics
BioJack Percelay has a 25+ year career in pediatric hospital medicine, beginning before the term hospitalist was invented when he started as an "in-house pediatrician in 1991 at several Bay Area hospitals after a brief career as a civilian primary care pediatrician at local and international US military bases. He has spent the majority of his career in community hospitals where his practice has run the gamut from the general pediatric ward and emergency room, to the PICU and intensive care nurseries, delivery room, and specialized neurologic and neurosurgical units.

Marco Perez
Associate Professor of Medicine (Cardiovascular Medicine)
BioDr. Marco Perez's research goal is to better understand the fundamental causes of cardiovascular disease through the study of genetics and epidemiology. His group studies the genetic variations and environmental exposures that are associated with conditions such as atrial fibrillation and heart failure. He has led the studies of atrial fibrillation in Women's Health Initiative, one of the largest nation-wide population-based cohorts. He is currently conducting a large study monitoring for silent or asymptomatic atrial fibrillation in women from the WHI randomized to exercise intervention, and was co-PI of the Apple Heart Study, a clinical trial that validated the ability of a smartwatch to detect atrial fibrillation. He is now PI of the Clinical Coordinating Center at Stanford for the REACT-AF which is a clinical trial to evaluate efficacy and safety of a "pill-in-the pocket" approach to anticoagulation for AF using a smartwatch. He is interested in understanding the paradox that atrial fibrillation is less common in African Americans and Hispanics, despite a greater burden of risk factors such as hypertension. As director of the Stanford Inherited Arrhythmia Clinic, he evaluates families with rare inherited arrhythmias associated with sudden death such as Long QT and Brugada Syndromes and explores their links with novel genes. He also studies the genetic causes of very early onset atrial fibrillation. He also studies how best to use the electrocardiogram and imaging modalities using Machine Learning techniques to identify patients at risk for cardiovascular disease. Dr. Perez receives funding from the NIH/NHLBI, Apple Inc., Janssen and the Colson Foundation.

Claudia Katharina Petritsch
Associate Professor (Research) of Neurosurgery
Current Research and Scholarly InterestsThe Petritsch lab broadly investigates underlying causes for the intra-tumoral heterogeneity and immune suppression in brain tumors from a neuro-developmental perspective. Defective cell fate decisions fuel the intra-humoral heterogeneity and plasticity in human brain tumors and may contribute to immune suppression. We use patient-derived models as avatars to study how brain cells control the fate of their progeny, whereby we unravel novel points of vulnerabilities in brain tumor cells.

Martin Pfaller
Instructor, Pediatrics - Cardiology
BioMartin R. Pfaller is an Instructor in the Department of Pediatrics (Cardiology) in the group of Alison L. Marsden. He received his B.Sc., M.Sc., and Ph.D. in Mechanical Engineering from the Technical University of Munich, working with Wolfgang A. Wall. During his Ph.D., he validated an efficient yet physiologically accurate boundary condition to account for the mechanical support of the heart within its surroundings, which has been adopted by various research groups worldwide. He further demonstrated how projection-based model order reduction could speed up model personalization from patient data, such as magnetic resonance imaging or blood pressure measurements. His current work focuses on cardiovascular fluid dynamics. He developed reduced-physics models to make blood flow simulations faster and more reliable. Further, he developed a fluid-solid-growth interaction model in blood vessels. His future research will predict the heart’s long-term function in heart diseases, supported by an NIH Pathway to Independence Award (K99/R00) and Stanford MCHRI Instructor K Award Support. He will quantify the risk of heart failure after a heart attack with a stability analysis validated with imaging data in swine and humans. This research will improve our understanding of biomechanical mechanisms leading to heart failure and help to identify patients at risk, enable personalized therapies, and facilitate the optimal design of medical devices. As an Assistant Professor, Martin will start his research group at Yale University in the Department of Biomedical Engineering in July 2024.

Suzanne Pfeffer
Emma Pfeiffer Merner Professor of Medical Sciences
Current Research and Scholarly InterestsThe major focus of our research is to understand the molecular basis of inherited Parkinson's Disease (PD). We focus on the LRRK2 kinase that is inappropriately activated in PD and how it phosphorylates Rab GTPases, blocking the formation of primary cilia in specific regions of the brain. The absence of primary cilia renders cells unable to carry out Hedgehog signaling that is critical for neuroprotective pathways that sustain dopamine neurons.

Trung Hoang Minh Pham
Assistant Professor of Pediatrics (Infectious Diseases)
Current Research and Scholarly InterestsUncovering mechanisms of tissue immunity and immunophysiology during persistent infection
The immune system safeguards the health of complex organisms by rapidly eliminating invading pathogens, curbing infection-induced tissue disruptions, and maintaining tissue homeostasis. Many bacterial pathogens evade host antimicrobial mechanisms and persist in infected tissues at low levels for long periods of time even in the presence of innate and adaptive immune resistance. During persistent infection, the immune system simultaneously orchestrates antimicrobial responses to contain the pathogen, repairs damaged tissue, regulates nutrient resources, and maintains other tissue physiologic functions to ensure host survival. Failure of any of these tasks leads to uncontrolled infection, devastating disease, and even death. The goals of our research are to understand:
1)What are the innate and adaptive immune cellular mechanisms that contain pathogens during persistent infection?
2)How are tissue physiological functions, such as tissue repair and nutrient regulation, maintained during persistent infection?
3)How do pathogens survive innate and adaptive antimicrobial mechanisms in infected tissues?
4)How does persistent infection impact host immunity to secondary infections of a similar or different pathogen?
Through investigating these fundamental questions, we may be able to decode the underlying cellular and molecular mechanisms that can be harnessed to eradicate infections and help restore health after an infectious insult. We employ animal infection models and bring together immunology, tissue biology, microbiology, and genetics to uncover the mechanisms of tissue immunity and immunophysiology during persistent infection from the molecular to organismal level.
Current areas of research:
•Development, maintenance, and plasticity of macrophage functional diversity in infected tissue
•Tissue repair and nutrient regulation during persistent infection
•Cellular dynamics and bacterial persistence in lymphoid organs
We are looking for highly motivated team members who are passionate about making impactful scientific discoveries to join our group at all levels. For opportunities and positions available for pre-doctoral students and postdoctoral fellows, please contact tpham8@stanford.edu! -
