Derya Demirtas is an assistant professor at the Center for Healthcare Operations Improvement & Research (CHOIR) in the Department of Industrial Engineering and Business Information Systems at the University of Twente.

She received her BSc in Industrial Engineering with a double major in Computer Engineering from the Middle East Technical University, Turkey (2008). She then received her MMath in Combinatorics & Optimization from the University of Waterloo, Canada (2010), and her PhD in Industrial Engineering from the University of Toronto, Canada (2016). She was recognized by the American Heart Association with the Young Investigator Award in 2015. She won the best poster abstract presentation award by the National Association of EMS Physicians (NAEMSP) in 2016. She was a finalist for the Three Minute Thesis Competition at the University of Toronto (2014). She also received the second place in the INFORMS Section on Public Sector Operations Research (PSOR) best paper competition (2012).


Operations research, optimization, spatial data analytics and their applications in healthcare and humanitarian sector: in particular, linear and integer programming, facility location under uncertainty, covering problems, spatiotemporal trend analysis, public health resource planning, post-disaster recovery and emergency service location problems.


The focus of Dr. Demirtas’s research is on data-driven decision making aimed at improving healthcare and humanitarian systems. Her projects include:
