Christine Samuel-Nakamura worked for multiple years in several Indian Health Service (IHS) and tribal hospitals/clinics as a nationally board certified Family Nurse Practitioner (FNP). A portion of her clinical work focused on chronic health conditions such as diabetes, renal failure, autoimmune disorders, and cancer. Her clinical work with these chronic health conditions led her to contemplate whether there is a connection between these chronic conditions and the community environment. These hypotheses ultimately led to her research question and work examining environmental contamination from U and other heavy metals. Dr. Samuel-Nakamura received her doctorate from UCLA and her dissertation study focused on U and associated heavy metals in the food chain on the Diné (Navajo) reservation. Her postdoctoral work examined U and heavy metals in a common AI herbal tea plant. Before joining the UCLA SON, Dr. Samuel-Nakamura was a Lecturer in the UCLA Interdepartmental Program in American Indian Studies (IDP-AIS). She is a member of the Diné Nation.

Dr. Michael Jerrett is an internationally recognized expert in Geographic Information Science for Exposure Assessment and Spatial Epidemiology. He is professor and chair of the Department of Environmental Health Sciences in the Fielding School of Public Health at UCLA. Dr. Jerrett earned his PhD in Geography from the University of Toronto (Canada). For the past 15 years, Dr. Jerrett has researched how to characterize population exposures to air pollution and built environmental variables, how to understand the social distribution of these exposures among different groups (e.g., poor vs. wealthy), and how to assess the health effects from environmental exposures. Over the decade, Dr. Jerrett has also studied the contribution of the built and natural environment to physical activity, behavior and obesity. In 2009, the United States National Academy of Science appointed Dr. Jerrett to the Committee on “Future of Human and Environmental Exposure Science in the 21st Century.” The committee recently concluded its task with the publication of a report entitled “Exposure Science in the 21st Century: A Vision and a Strategy.” In 2013, the U.S. Environmental Protection Agency appointed Dr. Jerrett to the Clean Air Scientific Advisory Sub-Committee for Nitrogen Oxides. In 2014, Dr. Jerrett was named to the Thomson Reuters List of Highly Cited Researchers, indicating he is in the top 1% of all authors in the fields of Environment/Ecology in terms of citation by other researchers.

He has served on the National Advisory Council of the National Health Service Corps, as a Commissioner of Public Health for LA County and is presently a member of the Board of Trustees of the Drew University of Medicine and Science in South-Central LA. His professional interests include health policy, the science of health care delivery and the provision of care to underserved and minority communities. A common thread in his career has been the linkage of graduate medical education to underserved communities as a means to improve access and reduce health outcomes disparities among racial and ethnic minorities. Further, his research interests include chronic disease management, cross cultural and bi-national medicine and the integration of substance abuse treatment programs within primary care. He is Co-founder and Associate Director of the UCLA Department of Family Medicine IMG program, an innovative program to prepare bilingual (English-Spanish) International Medical Graduates (IMGs) to become eligible for licensure and residency training in Family Medicine in California. Ever since his days as Medical Director of the United Farm Workers Clinics (UFW) under Cesar Chavez in California?s Coachella and Imperial valleys he has believed that health care is a unique social goal and basic right. He remains optimistic that President Obama and the Congress will finally do what 7 presidents since Franklin Roosevelt tried and failed, that is to provide universal coverage for all, like the rest of the industrialized world.
The focus of the laboratory is to determine the reasons for differential mouse strain responses to chemical agents that cause birth defects (teratogens). One of the malformations that has been induced by a wide variety of teratogens is postaxial forelimb ectrodactyly (absence of digits with the highest prevalence in the fifth digit then the fourth then the third, etc.) which occurs preferentially on the right limb as opposed to the left limb. This malformation has been produced in mice with acetazolamide, cadmium, carbon dioxide, dimethadione, diphenylhydantoin, ethanol, hyperthermia, retinoic acid (13-cis- and all-trans-) and valproic acid. These compounds include many documented human teratogens. In all cases where both the C57BL/6 and SWV mouse strains have been examined with these agents, the C57BL/6 strain is highly susceptible compared to the SWV strain. The goal of our experiments is to determine the reason for this consistent differential susceptibility. Alternatively, several teratogens have been examined in the same two strains for the ability to induce the neural tube defect exencephaly. For this malformation, the relative strain susceptibility is dependent on the specific teratogen. Thus, for some agents the C57BL/6 mouse is more susceptible and for other agents the SWV is more susceptible. Approaches that have been used to generate hypotheses regarding the cause of these strain differences include whole genome scanning followed by positional cloning, gene expression profiling, proteomic analysis, determining synexpression of limb development genes during the embryonic period following administration of the teratogen, and examining other malformations induced by the teratogens when administered at different gestational times that share the same strain susceptibility. Ongoing experiments are designed to determine the reasons for the different strain responses.
