As a graduate student at LSU in 1987, I focused my Master's thesis on the development of a probabilistic model for the free-replacement warranty policy. In this groundbreaking work, I introduced the concept of a "two-attribute" warranty policy and applied this model for the first time to the 5-year, 50,000 mile protection plan in the US automobile industry.

During my Ph.D. studies at Purdue University, my dissertation focused on sequential decision-making under conditions of uncertainty. The optimal decision strategy developed in my research can be applied to a wide range of scenarios, including job searching, candidate hiring, stock trading, and selling assets in open markets. (I take great pride in my accomplishment of completing the Ph.D. program and earning my doctoral degree in less than three years, from the beginning to the end.)

My research interest lies in the field of probabilistic modeling of managerial decision problems. Over the course of my career, I have published numerous papers on a wide range of topics, including product warranty analysis, sequential decision models, statistical quality control, product reliability, repetitive inspection plans, project management, and customer response modeling.

I am increasingly fascinated by advanced estimation methods and their applications, including empirical Bayesian method, Gibbs sampling, Markov chain Monte Carlo (MCMC) methods, expectation-maximization (EM) algorithm, kernel density estimation (KDE), and artificial neural network (ANN). Last summer, I dedicated my time to learning the Python programming language. It just goes to show that you can indeed teach an old dog new tricks!
