Dr. Sacha is an innovative infectious disease researcher with over 20 years of experience in infectious disease and immunology research and an established track record in the development of novel therapeutic modalities and prophylactic vaccines in humans and nonhuman primates (NHPs). His group has made discoveries that have informed human clinical trials and pioneered new NHP models of human disease, including the first macaque models of HBV infection and fully MHC-matched allogeneic stem cell transplantation. He is also a recognized expert in cellular immunology and described the first evidence of retrovirus-specific MHC-E-restricted CD8+ T cells. Dr. Sacha moved to OHSU in 2011 as an Assistant Professor after receiving his Ph.D. in Medical Microbiology & Immunology at the University of Wisconsin-Madison. In 2023, he became Chief of the Division of Pathobiology and Immunology. His research program has been continuously funded by the NIH for over a decade, and he holds nine awarded patents, serves as a member of the scientific advisory board for a publicly traded biotechnology company, and has co-founded a biotechnology company developing therapeutics for infectious diseases.

Kathleen Grant, Ph.D., Chief, Division of Neuroscience

Dr. Grant over the past two decades has achieved eminence as a leading investigator of the behavioral pharmacology of alcohol abuse and alcoholism.  Dr. Grant's laboratory has helped to define the receptor mechanisms that mediate the addictive potential of ethanol in the brain.  Further her research has developed a monkey model of alcoholic drinking that is the basis for over 30 laboratories involved in collaborative research on the genetic, physiological, endocrinological and neuropharmacological risk for and consequences of heavy drinking. Dr. Grant directs the consortium on the Integrative Neuroscience Initiative on Stress and Alcoholism funded by NIH and has served on the National Advisory Council for the National Institute on Alcohol Abuse and Alcoholism. After training at the University of Washington, University of Chicago, and the National Institutes of Health she rose up through the faculty ranks at Wake Forest University School of Medicine.  Dr. Grant moved to OHSU in 2005 to be jointly appointed in the Department of Behavioral Neuroscience and the ONPRC. In 2011, she became Division Head of Neuroscience and remains actively involved in the Behavioral Neuroscience Department where she will continue to hold an appointment as Professor.  

Shawn Chavez, Ph.D., Interim Chief, Division of Reproductive & Developmental Sciences

Shawn L. Chavez is an Associate Professor and the Interim Chief of the Division of Reproductive & Developmental Sciences at the Oregon National Primate Research Center (ONPRC), where she has been a faculty member since September of 2013. She also has affiliate appointments in the Departments of Obstetrics & Gynecology, Molecular & Medical Genetics, and Biomedical Engineering at Oregon Health & Science University (OHSU). She obtained her Ph.D. in Molecular, Cellular and Developmental Biology from Yale University and completed her Postdoctoral training at the University of California, San Francisco and Stanford University. Her research interests focus on the use of real-time imaging and low-input next-generation sequencing to investigate the genetic, epigenetic, and chromosomal requirements of early embryogenesis and placentation in humans, non-human primates (NHPs), and other mammals. In particular, her laboratory is investigating the underlying mechanisms mediating meiotic versus mitotic chromosome mis-segregation, embryonic micronuclei formation, and potential aneuploidy resolution during peri-implantation development. Moreover, she is also examining the molecular connections between the formation of the placental-derived trophectoderm layer in embryos and subsequent placentation between normal and complicated pregnancies in both humans and NHPs. Collectively, the goals of this research are to enhance our understanding of embryogenesis and placentation across primate species, whilst improving assisted reproduction outcomes for infertile couples by preventing embryo or fetal loss during pregnancy.

Paul Kievit, Ph.D., Chief, Division of Metabolic Health & Disease

Paul Kievit is an Associate Professor and Interim Chief of the Division of Metabolic Health & Disease. Dr. Kievit has several areas of interest with an overall focus on the impact of obesity and energy homeostasis on human health, as well as understanding how particular therapies can intervene. A diverse and highly motivated team investigates areas such as the impact of maternal obesity on the developing metabolic systems in the offspring, the contribution of obesity to diseases like HIV and Covid-19 and studying novel therapies for weight loss and type-2 diabetes.  His laboratory uses techniques like pancreatic islets isolations, immunohistochemistry approaches like RNAscope in tissues and numerous in-vivo animal techniques like hyperinsulinemic-euglycemic clamps and intravenous glucose tolerance tests to determine the impact on the pancreas and other organs.   As a highly collaborative scientist, he has facilitated interactions with scientists on a global level to provide access to the nonhuman primate obesity model he has developed. Before joining the faculty at ONPRC in 2014, Dr. Kievit received his initial training in neurotoxicology at Leiden University in the Netherlands, continued training at Oregon Health & Science University in the Department of Cell and Developmental Biology as well as postdoctoral training at the Beth Israel Deaconess Medical Center and Harvard Medical School.

Donald Conrad, Ph.D., Chief, Division of Genetics

Dr. Conrad is a world-renowned expert in genetics/genomics and the development of bioinformatics pipelines/platforms for the efficient assessment and management of genetic data. He played a leading role in mapping and characterizing the functional impact of human chromosomal structural variants. He also developed novel statistical methods for identifying de novo point mutations from next-generation sequencing data and used this to estimate germline mutation rates from parent-offspring trios as part of the 1000 genomes project. Another major emphasis of his research includes defining the origins of mutation and the distribution of mutation frequencies that impact gametogenesis, fertilization, and pregnancy. Dr. Conrad received his training at the University of Chicago and the Wellcome Trust Sanger Institute prior to joining Washington University in St. Louis, where he led a successful research group in the Department of Human Genetics. Dr. Conrad joined the ONPRC in 2018 to lead the newly established Division of Genetics.
