My name is Hrayer Aprahamian, and I am an Assistant Professor in the Department of Industrial and Systems Engineering at Texas A&M University. I am also affiliated with Texas A&M Energy Institute. My research interests lie at the interface of Operations Research and Machine Learning. Specifically, my research focuses on combinatorial/discrete optimization, and network analysis, in which I work on finding new solution techniques and efficient algorithmic approaches to solve difficult optimization problems. Applications of my work include high-dimensional cluster analysis, risk classification procedures, and large-scale screening of heterogeneous populations. I am particularly interested in applications related to healthcare systems and public policy decision-making. For more information, please visit research and publications. Prior to joining Texas A&M, I obtained my Ph.D. in Industrial and Systems Engineering at Virginia Tech, where I was advised by Professors Ebru K. Bish and Douglas R. Bish.
