Dr. Abhaya Indrayan

PhD

Introduction

Abhaya Indrayan completed Master’s and PhD in Biostatistics from the Ohio State University. He has been working in medical institutions since the beginning of his career and has extensively interacted with his medical colleagues for their research endeavors. He is the founder Chair of the Department of Biostatistics and Medical Informatics at Delhi University College of Medical Sciences, and has endeavored to redefine the subject of biostatistics to medical issues so that it is perceived as a medical and not as a mathematical subject. His popular book Medical Biostatistics (CRC Press), now into the Fourth Edition, serves this purpose well and has been extensively hailed as ‘perhaps the most comprehensive book on biostatistics’ and ‘encyclopedic in breadth’. His Concise Encyclopedia of Biostatistics for Medical Professionals (CRC Press 2016) is making extensive appeal all over the world. Dr Indrayan has more than 230 publications to his credit and has completed a large number of biostatistics-related projects for the World Health Organization, the World Bank, and the UNAIDS.
