Background and Expertise:

Dr. Usha Govindarajulu is an Assistant Professor of Biostatistics. She received her PhD in Biostatistics from Boston University, her MS in Biostatistics from George Washington University, and her AB from Cornell University. She also did her post-doctoral work in Biostatistics at Harvard School of Public Health.

Dr. Govindarajulu's major statistical research interests are in survival analysis, frailty models, smoothing, genetic epidemiology, and non-parametrics. Her area of medical expertise is in cardiology, allergy and immunology, radiology, and translational research.

She is also a member of the American Statistical Association and has served as Secretary/Treasurer of the Section of Statistical Computing.
