Email id: statistics.lbc@gmail.com

Educational Qualification:

  • Ph.D.; University of Calcutta, Kolkata, India
  • DOEACC  ‘A’  Level Course (Equivalent to Advanced Diploma in Computer Application)
  • M.Sc. in Statistics ; University of Kalyani, Nadia, West Bengal, India

Specialization: Applied Multivariate Analysis, Operation Research

  • B.Sc. in Statistics; University of Kalyani, Nadia, West Bengal, India

Career History:  Teaching experience of 13 years

  • Full-time faculty on contract basis at Acharya Prafulla Chandra College, New Barrackpore, Kolkata – from June, 2005 to February, 2007
  • Full-time regular faculty at Bengal Institute of Technology and Management, Bolpur from February, 2007 to November, 2008

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.
