Research Expertise

My research focuses on the exploration and analysis of factors of uncertainty for organizations and supply chains to develop decision-making mechanisms. For Policy Development for Critical Services: Healthcare, I conducted research at Duke University Medical Center in 2011, on attrition uncertainty in medical residency programs. This effort resulted in two publications (SCI-E in 2013 and ABS-3 in 2015), along with a manuscript currently under revision (ABS-2). Applying the stochastic optimization method developed for these projects to Operations and Supply Chain Management led to two other former publications (ABS-4, ESCI) in 2019. Within the Operations and Finance Interface domain, I've published two works (SCI-E/Q2 in 2022 and ABS-1 in 2023) with funding from the European Union Scholarship Programme for the Turkish Cypriot Community to support hosting my co-author for a research visit to Trinity. My ongoing work in this area includes the project "Why integrate blockchain into the cross-border payments system at banks? SWIFT vs Ripple," a collaborative effort with Dr. Sule Nur Kutlu (University of Calgary, Canada) and Dr. Orkun Bayram (Istanbul Gedik University, Türkiye), aiming to construct a game-theoretic model of global cross-border payment systems. My other ongoing research: 1) focuses on Policy Development for Critical Services, specifically Entrepreneurial Support Structures for Refugees. I presented this project at an EU-funded conference in April 2023, the project's extended abstract is published, and the manuscript is under review for an ABS-3 journal. 2) include Policy Development for Critical Services in Higher Education, with a manuscript currently under review (ABS-1), and 3) Operations Management and Marketing Interface. In this latter domain, I expanded my research methods portfolio, incorporating machine learning tools for customer churn prediction (manuscript currently under review ABS-1) alongside stochastic optimization applied to pricing problems in two publications from my doctoral years (SCI-E in 2009, and a proceeding in 2005).
