Research:
I have two main research interests, statistical regression modelling and functional data analysis. I am specifically interested in developing methods for shape preserving smoothing within generalized additive models and applications of shape constrained additive models (SCAMs). I've written an R package `scam' which implements SCAM. The short description of this package is given below. I am also interested in methods for clustering functional data with optional scalar covariates and applications of functional clustering.

I have been teaching undergraduate, graduate and executive MBA courses in the areas of probability, statistics, applied statistical and quantitative methods, business time series forecasting, regression analysis, and design of experiments.
Currently, I am involved in teaching the following courses:
