Dr. Subhradev Sen

Assistant Professor

Alliance School of Business

Dr. Subhradev Sen holds a doctoral degree in Statistics from Pondicherry Central University, Puducherry, India and a first class first Master’s degree in Statistics from Visva Bharati University, Santiniketan, India.

He teaches Business Statistics, Managerial Mathematics, Business Research Methodology, and Quantitative Methods in the University and is now working as Coordinator for SWAYAM, Alliance School of Business. He has thirteen years of teaching, industry, academic, and research experience in statistics and related fields.

Before joining to Alliance University in August 2016, he served the Division of Clinical Research & Biostatistics, Malabar Cancer Centre (an Autonomous Centre under the Govt. of Kerala), Kerala, India, as a Lecturer in Biostatistics for three and half years in a permanent position. He taught post graduate level Statistics in the Department of Statistics, Pondicherry University, India, during July 2006 to April 2010 as a Lecturer in Statistics. During 2010-2012, he served Advanced Medicare & Research Institute, Kolkata as a Statistician. Was a visiting faculty at Bio-equivalence Study Centre, Jadavpur University, Kolkata, India, during 2011-2012. He has given invited talks on Statistics in the PG Centre, Pondicherry University, Karaikal, India, Kerala University of Health Sciences, Thrissur, India, Pariyaram Medical College, Kerala to name a few.

Dr. Sen is actively involved in research. His major area of research includes Distribution Theory, Reliability Studies & Statistical Quality Control, and Survival Analysis. He has introduced in statistical literature a new probability distribution, namely the “xgamma distribution”, which has been gaining popularity among researchers for modeling lifetime data in the different parts of the globe. Another contribution, with his coauthor, has been in the field of reliability by the name of “Augmentation Strategic Plan” (ASP) based on which a UGC funded major research project has successfully been completed by the Department of Statistics, Pondicherry University, India.

He is presently concentrating in the areas, like, Circular Statistics, Record Statistics, Measures on Bio-Diversity Losses, and Environmental Statistics.
