Ph.D., epidemiology, University of California, Los Angeles; B.A., public health, University of California, Berkeley
Summary of Experience
Dr. DerSarkissian’s expertise includes the application of epidemiologic methods to real-world evidence (RWE) generation in support of product registration, post-approval safety studies, and health economics and outcomes research (HEOR). She has served as an expert witness in litigation and has a wide range of experience in pharmacoepidemiology, biostatistics, and observational data analysis, including in studies on causal methods. Dr. DerSarkissian has provided regulatory and strategic consulting on drug and medical device registration and conducted RWE studies related to US Food and Drug Administration (FDA) and European Medicines Agency (EMA) submissions. She has conducted cost-effectiveness and comparative effectiveness studies; examined treatment patterns, drug adherence, health care resource utilization and costs, and clinical outcomes; assessed direct medical and indirect productivity costs of a disease burden; and assessed patient-reported quality of life and the humanistic burden of a disease. Dr. DerSarkissian has used data from electronic medical records, clinical trials, commercial insurance claims, patient surveys, and medical chart review studies in disease areas that include obesity; HIV/AIDS; cardiovascular diseases; schizophrenia; autoimmune, neurologic, and rare hereditary disorders; and many types of cancer. She has presented her research at conferences on epidemiology and health services, and published articles in a number of peer-reviewed journals. Dr. DerSarkissian is an adjunct assistant professor in the epidemiology department at the UCLA Fielding School of Public Health.
