I am working as an assistant professor in statistics in the Department of Mathematics and Statistics at Thompson Rivers University (TRU). Before joining TRU, I worked as an assistant professor (nontenure track) in the Department of Computer and Mathematical Sciences at the University of Toronto Scarborough. I have received my PhD in statistics with a specialization in statistical machine learning from the Department of Statistics, The University of British Columbia, Vancouver. I have two MSc degrees: (i) from the Department of Mathematics and Statistics (in Statistics) at the University of Windsor, and (ii) from the Department of Statistics (in Biostatistics) at the University of Dhaka, Bangladesh.

My research interest is in statistical machine learning, Bayesian statistical inference and statistical ecology. The main focus of my research is in developing ensemble method to improve its prediction performance by exploiting the richness of useful variables in high-dimensional data and identify important models and variables to answer important research question. I have shown application of my ensemble/model in (i) drug discovery to detect drug like active bio-molecules for development and (ii) protein homology to detect homologous proteins and produce evolutionary sequences of proteins. These days, I am focusing more on developing Bayesian and computational models for ecology, health-care, housing market, and genetics data.
