Education:

  • 2009 - Present • MIT: PhD candidate in Engineering Systems 
    Advisor: David Simchi-Levi
    Committee: David Simchi-Levi (MIT), Vishal Gaur (Cornell University), Roy Welsch (MIT)
  • 2003 - 2004 • MIT: Master of Engineering in Supply Chain Management
  • 1996 - 2000 • Istanbul Technical University: BS in Industrial Engineering

Research Domain:

supply chain management

Research Methodology:

econometrics, analytical modeling

Research Description:

My dissertation focuses on the unsaleables (i.e. product waste) issue in the consumer packaged goods (CPG) industry.

The first paper in my dissertation empirically investigates the root causes of product expiration that are beyond demand uncertainty, collaborating with a CPG manufacturer. The research shows that sources of expiration is not limited to inventory management at retail stores and spans multiple functions and organizations within the channel. Further, expiration can be alleviated by better management at manufacturers and retailers (i.e. case size and supply chain inventory management, improvement of retail shelf allocation).

The second paper in my dissertation examines optimum shelf allocation mechanisms considering the impact of product expiration. We analyze shelf allocation based on a multi-product shelf allocation model considering profit, expiration cost, and shelf life. The model maximizes total net profit under a total shelf capacity constraint.

My research plans for the near future include drivers of supply chain aging of inventory, optimization of supply chain aging targets, strategies to manage supply chain inventory considering expiration and batching, and incentive issues related to unsaleables.
