Arun Karlamangla, MD, PhD

Arun Karlamangla, MD, PhD

Director of Journal Clubs & Clinical Supervisor

Arun Karlamangla, PhD, MD, received his PhD in Electrical Engineering from the University of Southern California and his MD from the University of Michigan Medical School. He is a geriatrician and clinical epidemiologist at the University of California, Los Angeles. In addition to residency and fellowship training in internal medicine and geriatrics, he brings doctoral training and years of teaching and experience in statistical signal processing, as well as expertise and experience in biostatistics to aging epidemiology research. Dr. Karlamangla pioneered the assessment of bone strength relative to load, which has proven to be immensely valuable in explaining paradoxical differences between fracture risk as predicted by bone density and observed fracture risk in different population sub-groups. He was one of the first to show that contrary to earlier trends, disability rates in older Americans were actually on the rise, and he introduced the notion of cortisol diurnal dynamic range as a marker of adversity-related dysregulation of the hypothalamic-pituitary-adrenal axis. He has also contributed extensively to the literature on changes in bone health and body composition during the menopause transition, and to the literature on biological pathways by which psychosocial factors affect health over the life course, including one of the first demonstrations of the effect of the 2008 Great Recession on blood pressure in a national sample. He has taught graduate-level courses on statistics, both to engineering students (at the University of Illinois, Urbana Champaign) and to clinical research students (at UCLA). Dr. Karlamangla has served as director of the analysis and cost-effectiveness core of the UCLA Claude D. Pepper Older Americans Independence Center (OAIC), and as co-director of the statistics core of the national Midlife in the United States Study (MIDUS). He is currently one of the multi-principal investigators of the Study of Women’s Health Across the Nation (SWAN), and chair of the CoVPN (COVID-19 Prevention Network) Older Adults and Veterans Expert Review Panel, that is providing recommendations relevant to older adults and veterans for 5 COVID-19 vaccine trials and 2 antibody treatment trials.
