Research Interests

My personal research interests lie in the area of Reliability theory, Queueing theory, and analysis of optimization problems. My doctoral dissertation focused on “Reliability Analysis of Reparable Systems with Dependent Structure.” I try to work as much as possible with upper level students in statistics on projects, as well as senior papers that result in a presentation of research papers at some conference.
