Area of Research:
My area of research is primarily focused on proposing some inferential techniques in the domain of species growth.  My research works include offering a few novel and advanced goodness-of-fit tests as well as some model selection criteria for growth curve models. Goodness-of-fit tests are the very important tools to calculate the proximity between a real data set and a theoretical model, and hence enjoy immense practical value in real data analysis in the context of biological growth.  From a set of eligible models, model selection criteria help to choose statistically the best one. I have also worked on the change point problems in growth systems. A change or a shift is very likely to occur in a growth journey as it is a dynamic process, and is required to be handled with proficiency for a satisfactory data analysis.

Research Interest:
•    Inference in Growth Curve Modelling
•    Change Point Problems
•    Ecological Statistics

Research Experience:
•    Worked on a research project as a part of the doctoral degree.

Thesis Title: On growth curve analysis and related statistical problems incorporation biological and ecological issues

•    Worked on a Multidisciplinary Research Project on East Kolkata Wetland representing Department of Statistics, Lady Brabourne College. The project was jointly done by the six departments of this college: Microbiology, Chemistry, Botany, Zoology, Geography and Statistics.
