ABOUT ME
ABOUT ME
I am currently a Professor of Business Analytics in the Department of Operatioins, Business Analytics and Information Systems at the Lindner College of Business, University of Cincinnati, USA. I also serve as Academic Director of the Center for Business Analytics, where I lead the premium data, analytics, and AI hub in the Greater Cincinnati metropolitan area. I hold a Ph.D. degree in Statistics from Rutgers University and completed my postdoctoral training at Yale University.
My research interests include data fusion, discrete data, model transparency, personalized inference, and data/AI readiness. My work addresses challenging problems across a wide range of domains, including healthcare, medicine, psychology, sociology, information systems, and insurance. My research has been published in leading statistics and data science journals including the Journal of American Statistical Association, Annals of Applied Statistics, and Biometrics.
As an award-winning educator in business analytics, I am recognized for my interative and case-based teaching, which is highly valued by both students and industry professionals. Motived by the strong interests in business applications and industry collaborations, I have led and directed consulting projects for Fortune 500 companies acoss sectors. In recoganition of my contributions to research, teaching, and service, I have received college- and university-level awards, including Lindner Research Excellence Emerging Scholar Award (2017), Award for Faculty Excellence (2020), and Daniel E. Westerbeck Junior Faculty Graduate Teaching Award (2021).
