Nataliya Kovalchuk
Clinical Professor, Radiation Oncology - Radiation Physics
BioNataliya Kovalchuk is a Clinical Professor at Stanford Radiation Oncology department and an Adjunct Professor at MD Anderson Cancer Center. She completed her residency at Mayo Clinic and worked at Massachusetts General Hospital/Boston Medical Center/Harvard Medical School. Dr. Kovalchuk is one of the leaders in the clinical implementation of Biology-Guided Radiotherapy and auto-planning techniques for Total Body Irradiation (TBI), Total Marrow Lymphoid Irradiation (TMLI), and Cranio-Spinal Irradiation (CSI), with more than 200 publications and presentations. She serves on multiple committees at AAPM, ASTRO, NRG, COG, and volunteers for ABR as an examiner. She is also a physics chair for four NRG and COG clinical trials, physics lead for the NRG Head and Neck committee and the VMAT TBI workgroup. In recognition of her educational efforts, she has been honored with six teaching awards from ARRO, AAPM, Stanford, and Harvard. Since the full-scale russian invasion of Ukraine, Nataliya directed her efforts to helping Ukraine as a co-founder and president of Help Ukraine Group. Her dedication was recognized with the Richard Hoppe Leadership Award and the Parliament of Ukraine Certificate of Merit for the Service to the People of Ukraine.

Izabela Kowalczyk
Postdoctoral Scholar, Developmental Biology
BioDr. Izabela Kowalczyk is a postdoctoral fellow in the laboratory of Dr. Sarah Bowling, Department of Developmental Biology. She is studying embryonic development, with a focus on heart valve formation and the influence of the maternal environment on this process. Dr. Kowalczyk completed her Ph.D. at the Max-Delbrück-Center for Molecular Medicine in Berlin, under the supervision of Dr. Annette Hammes, where she investigated cell and tissue morphogenesis during early forebrain development. Her work identified novel components of Sonic Hedgehog (SHH) signaling and primary cilia biology, providing new insights into the variable penetrance of holoprosencephaly in mouse models.

Michael Kozal
Professor of Medicine (Infectious Diseases)
BioDr. Kozal is a Professor of Medicine in the Division of Infectious Diseases and Geographic Medicine and is the Director of Operations for the Department of Medicine Clinical Research Hub. He previously served as Senior Associate Dean for Veteran Affairs at Stanford School of Medicine and Chief of Staff at VA Palo Alto Health Care System. Prior to coming to Stanford, he was a Professor of Medicine at Yale University School of Medicine and served as Associate Dean for Veteran Affairs at Yale University School of Medicine and the Chief of Staff at VA Connecticut Healthcare System.
Dr. Kozal is a translational researcher who has focused his research career on three areas: 1) investigating the genetic determinants of HIV and HCV drug resistance, 2) the development of new molecular methods to detect viral mutations, and 3) HIV and HCV clinical trials involving new drugs and diagnostic technology. Dr. Kozal is an expert in microarray and deep sequencing technology receiving patents for his work in genotyping. Dr. Kozal previously directed the Yale HIV Clinical Trials Group and has more than 20 years of experience in running clinical trials, serving as the principal investigator or site investigator on >40 HIV and Hepatitis C trials. He has served on multiple VA and NIH/NCI review panels and was a member of the DHHS/NIH Panel on Antiretroviral Guidelines for Adults and Adolescents from 2015-2024.
Dr. Kozal is currently serving as the overall Director of Operations for the Department of Medicine Clinical Research Hub. The key hub functions include research navigation, enhanced pre-award support for budgeting and submission strategy, streamlined contracting with research sponsors, a multisite clinical coordination center to coordinate and monitor complex studies, and a centralized digital platform for study design, data access, and analytics.
Dr. Kozal sees patients in the Infectious Diseases Clinic and the Valley Fever Clinic in Palo Alto. -
Fredric Kraemer
Gerald M. Reaven, MD, Professor of Endocrinology, Emeritus
Current Research and Scholarly InterestsOur research interests are in the general area of cellular lipid and lipoprotein metabolism. The work is aimed primarily at understanding the mechanisms regulating cholesterol and triglyceride accumulation in cells. We utilize a variety of techniques from cell biology, biochemistry, and molecular biology.
