As the name suggests, the subject econometrics aims to measure economic relationship. Using economic data and applying mathematical and statistical tools, it provides empirical validity of abstract economic theory. However, application of econometrics is not confined in the domain of economics, rather widespread application of econometrics is possible in other social science and pure science domains also. After successful completion of the course, students would be able to formulate econometric model to analyze data and then would be able to establish any cause-effect relationship in their preferred areas of interest like economics, finance, management, engineering and science. An expertise in econometrics increases the job prospect of the students significantly.

He has several national and international publications in his credit. He was awarded Young Economist Award 2015 by the Indian Econometric Society for his contribution to quantitative economics. Recently, he has been awarded Fulbright Nehru Academic and Professional Excellence Award 2020-21 (research category) for conducting research in the area of ‚ÄòCommunity Based Adaptation to Climate Change‚Äô taking Southeast Florida Regional Climate Change Compact (SFRCC) as a model for analysis. He aims to develop an economic framework based on rational choice theory, to identify the motivating factors that determine private participation in community based adaptation (CBA) focusing on individuals‚Äô perception about climate risk, time preference and their adaptive capacity
