Biographical Sketch 
Dr. Limdi graduated from Samford University obtaining a Pharm.D degree in 1994. She joined the Department of Hospital Pharmacy as a Pharmacy Specialist in Neurosciences. She continued her training obtaining an MSPH in Clinical Research in 2005 and PhD in Epidemiology in 2007. Dr. Limdi’s primary research focus is on pharmacogenetics/genomics of anticoagulation therapy and pharmacoepidemiology in cardiovascular phenotypes.

Research/Clinical Interest
Title
Pharmacogenomics research and Implementation Science
Description
Drug response is a complex phenotype depicting an intricate and complex interplay of genetic and environmental factors. Although overall response patterns among participants in clinical studies guides clinical practice, it is often difficult to predict individual patients’ response to medications. The emergence of pharmacogenetics offers hope to improve prediction of medication response with the potential benefit of increasing medication efficacy and safety. My work is focused on understanding genetic and environmental factors that influence drug response determine their relative contribution and understand the interplay between genes and environment. Anticoagulants, specifically warfarin is of particular interest. Warfarin, the most widely used oral anticoagulant, is limited by the capricious nature of patients’ response to any given dose. Warfarin’s narrow therapeutic index makes this variation potentially hazardous perhaps explaining warfarin’s consistent rank among the top 10 drugs associated with serious adverse events. With a network of collaborators in UAB and at other national and international institutions we are defining the genetic and environmental factors that influence warfarin dose and risk of hemorrhagic complications. Our approach is to use complementary approaches: candidate-gene and genome-wide association study in a prospective racially diverse cohort. The long-term goals are to use genetic and environmental predictors to tailor dosage and to predict individual risk of hemorrhage and to use this information to enable informed and personalized clinical decisions.
