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.

Claudia Katharina Petritsch
Associate Professor (Research) of Neurosurgery
On Partial Leave from 12/24/2024 To 10/31/2025Current 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.

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) and of Microbiology and Immunology
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 physiological 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, promote tissue resilience, and 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 -

Peter Pinsky
Professor of Mechanical Engineering, Emeritus
BioPinsky works in the theory and practice of computational mechanics with a particular interest in multiphysics problems in biomechanics. His work uses the close coupling of techniques for molecular, statistical and continuum mechanics with biology, chemistry and clinical science. Areas of current interest include the mechanics of human vision (ocular mechanics) and the mechanics of hearing. Topics in the mechanics of vision include the mechanics of transparency, which investigates the mechanisms by which corneal tissue self-organizes at the molecular scale using collagen-proteoglycan-ion interactions to explain the mechanical resilience and almost perfect transparency of the tissue and to provide a theoretical framework for engineered corneal tissue replacement. At the macroscopic scale, advanced imaging data is used to create detailed models of the 3-D organization of collagen fibrils and the results used to predict outcomes of clinical techniques for improving vision as well as how diseased tissue mechanically degrades. Theories for mass transport and reaction are being developed to model metabolic processes and swelling in tissue. Current topics in the hearing research arena include multiscale modeling of hair-cell mechanics in the inner ear including physical mechanisms for the activation of mechanically-gated ion channels. Supporting research addresses the mechanics of lipid bilayer cell membranes and their interaction with the cytoskeleton. Recent past research topics include computational acoustics for exterior, multifrequency and inverse problems; and multiscale modeling of transdermal drug delivery. Professor Pinsky currently serves as Chair of the Mechanics and Computation Group within the Department of Mechanical Engineering at Stanford.

Sharon Pitteri
Associate Professor (Research) of Radiology (Diagnostic Sciences Laboratory)
Current Research and Scholarly InterestsThe Pitteri laboratory is focused on the discovery and validation of proteins that can be used as molecular indicators of risk, diagnosis, progression, and recurrence of cancer. Proteomic technologies, predominantly mass spectrometry, are used to identify proteins in the blood that are differentially regulated and/or post-translationally modified with disease state. Using human plasma samples, tumor tissue, cancer cell lines, and genetically engineered mouse models, the origins of these proteins are being investigated. A major goal of this research is to define novel molecular signatures for breast and ovarian cancers, including particular sub-types of these diseases. This laboratory is also focused on the identification of proteins with expression restricted to the surface of cancer cells which can be used as novel targets for molecular imaging technologies.
