Academic Advisor

Dr. Ebru Bish and Dr. Douglas Bish

Education

  • Ph.D. in Industrial Systems Engineering (Operations Research), expected to graduate in May 2018
  • M.S. in Engineering Management (Financial Engineering), American University of Beirut, Lebanon
  • B.S. in Physics, Lebanese University, Beirut, Lebanon

Research Interests

My research interests lie in the application of Operations Research methodologies and statistical tools to problems arising in health care systems and public policy decision-making. My specific research focus is on the development of optimal risk-based screening policies and effective algorithms for public health screening. Applications include donated blood screening, population-level screening for sexually-transmitted diseases, and newborn screening for genetic mutations.

Research Methodologies

  • Stochastic Optimization
  • Robust Optimization
  • Combinatorial Optimization
