Hi there! I’m Chaya Weerasinghe.
I completed my Ph.D. in the Department of Econometrics and Business Statistics at Monash University, under the supervision of Emeritus Professor Gael M. Martin , Dr. Ruben Loaiza-Maya , and Professor David T. Frazier .
My doctoral research, Inference and Prediction in Misspecified Models , focuses on inference and prediction under model misspecification, with particular emphasis on applications in finance and macroeconomics. This work examines the impact of model misspecification on statistical inference and forecasting and develops novel methodologies to address the challenges it presents. Broadly, my research interests include model misspecification, Bayesian inference and forecasting, and approximate Bayesian methods.
My current research focuses on the development of Bayesian methods for infectious disease research, with particular emphasis on clinical trials and controlled human infection models.
In addition to my research, I have experience teaching econometrics and statistics at undergraduate and postgraduate levels.
