Eric Peterson
Casual - Non-Exempt, Neurology
BioI am a researcher with 10 years of experience in magnetic resonance imaging, which includes project management, data analysis, digital signal and image processing, image reconstruction, and pulse sequence design. I currently manage the day-to-day operations of a small animal MRI facility and work to ensure reliable data are collected for both human and animal imaging. I also work on MRI pulse sequence development, reconstruction, and analysis to better understand the sources and effects of alcohol addiction. I have also worked on clinical stroke imaging in CT and MRI, as well as techniques for high resolution 3D Diffusion-weighted MRI of the brain to better visualize white matter tracts in order to better detect the subtle changes associated with degenerative diseases such as Alzheimer's disease. I earned my PhD with a variety of work including cancer metabolism using hyperpolarized 13C, and data analysis of the effects of asthma on the lungs. My interests are research, technology, and healthcare.

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.

Edward A. Pham
Instructor, Medicine - Gastroenterology & Hepatology
BioMy interest in medicine and research was triggered by my mother’s battle with chronic hepatitis C, which made me realize the transformational power of biomedical research in treating patients. Therefore, my career goal is to become a physician scientist in the field of gastroenterology and hepatology dedicated to translating discoveries in the laboratory into novel medical treatment modalities. My research focus is alterations in phosphoinositides signaling and its pathogenesis in cancers of the hepatobiliary and luminal GI tract with the goal to identify novel targets for therapeutic intervention. I also have a particular interest in understanding the interface between chronic viral infection and cancer through studying how the innate and adaptive immune system are perturbed in chronic viral infections
