Nate’s current specialization is Econometrics and Statistics with emphasis on Bayesian approach and applications in economics, finance, health science, and social science. His research interests also lie in the fields of computational statistics using Monte Carlo methods, financial analytics, skew distributions, copula modeling, robust quantile regression, and GPU-based parallel computation.

Before joining AUT, Nate has been a research fellow at Thailand Development Research Institute and was a Lecturer in Statistics at University of Canterbury, New Zealand where he is now an Adjunct Fellow. Prior to that, he obtained a PhD in Econometrics from University of Sydney, Australia, and two MAs in Economics from Rutgers University, USA, and Chulalongkorn University, Thailand.
