Inmyung Choi is a 5th-year PhD candidate in Information Systems (IS) of the college of business at Iowa State University. He will complete his dissertation, under the supervision of Dr. Joey F. George, by July 2017. He earned his master’s degree from the department of management engineering in the college of business at KAIST. Before pursuing his PhD study, he worked at the subsidiary of Chevron and supported the role of Chief Information Officer and the initiatives of corporate innovation.
Research Interests: His research topic is broadly about the business value of information technology (IT). More precisely, he is interested in examining the contribution of IT (i.e., IT capability, IT investment, and the type of IT applications) on the competitive actions taken by firms and their eventual influence on firm performance. Theoretically, his work is grounded in competitive dynamics literature and the resource-based view. His primary research methods are econometrics, text-analysis, and survey. His works were presented at Americas Conference on Information systems (AMCIS), Academy of Management (AoM) annual meeting, and INFORMS Conference on Information Systems and Technology (CIST). Several essays of his dissertation are under review at premier journals in the IS area. One of his work was accepted at AIS Transactions on Replication Research. Also, he was invited to attend the Doctoral Consortium of International Conference on Information Systems (ICIS) 2016.
Teaching Interests: His teaching interests include both managerial and technical aspects of information systems. He taught ‘introduction to management information systems’ (4 sections) and was a teaching assistant for system design and analysis.

David Cortes is a fifth-year PhD candidate in Supply Chain Management. Before starting his career in academe David worked in the Supply Chain Department of a Fortune 500 multinational company. His desire to study major supply chain problems drove him to pursue a scholarly path.
In his doctoral dissertation David proposes a novel way to perform vehicle routing and scheduling based on a literature gap he identified in the fields of transportation and cross-docking. His three-essay dissertation targets premier-journals akin to Transportation Science and Decision Sciences.
