Research

Supply Chain and Operations Management (SCOM) is critical to converting a “good idea” in an organization, business, or society, into a “great execution”. Instead of treating SCOM as a stand-alone mechanism of delivering goods and services to customers, organizations are weaving it in their strategic interactions with their customers, competitors, and partners. Through my research, I aim to understand the strategic interactions among organizations, and between organizations and consumers, in the context of supply chains.

Two questions in supply chain research have been of particular interest to academia and practitioners: (1) how can organizations leverage supply chain elements to interact strategically with each other, and (2) how changing supply chain structures, such as those in multisided markets, fundamentally define the strategy of an organization. Using game-theoretic models, my research establishes and explains strategic trade-offs pertaining to these two questions. I provide intuition on existing problems as well as innovative strategies, in order to develop insights for academics and applicable to practitioners.

The answers to these questions contribute to the literature on supply chain coordination, contracts in supply chains, information flow in supply chains, and competitive strategy, as well as on platform strategy, the economics of multisided markets, and product innovation.

Research Agenda

My research converges to the broad idea of strategic interactions between agents in both traditional and evolving value chains. Using economic models of supply chain and information economics, I develop novel insights on the strategic use of a supply chain tool (inventory) or structure (openness of sides) by agents in a supply chain.

For managers and practitioners, my research provides formal rigor to the understanding of the strategic interactions in a value chain, which can be used to make better-informed decisions. I find interesting research ideas from an amalgamation of previously established theoretical models, as well as industry events and practices, either highlighted in the media or brought out during conversations with practitioners.

My research provides a platform for the interchange of academic ideas and practical innovation. My work has applicability in both operations management and information systems.
