My research lies at the intersection of supply chain risk management and network analysis. Specifically, I study supply network antecedents to supply chain risks and ways to mitigate the negative consequences of such risks. My methodological expertise lies in the areas of quantitative empirical methods (statistical models) based on survey and secondary data. Aside from my dissertation, I also collaborate with senior researchers to explore related research topics, such as corporate social responsibility, chief risk officer appointments, supply chain integration, and servitization.

Dissertation research

Essay 1: A cross-disciplinary literature review on product recalls


Research on product recalls has recently witnessed a sharp increase; however, this stream of research is dispersed within and outside the discipline of management. In this article, I review this research stream by adopting a stakeholder-stage framework that draws on stakeholder theory and crisis management literature.

Essay 2: Supply base complexity and automobile quality risks

This empirical essay examines the relationship between supply base complexity and quality risks, measured by the percentage of complaints and the number of recalls. I merged several databases to test the hypotheses, including (i) supply network data of the Chines automobile industry from the MarkLines database; (ii) passenger car complaint data from; (iii) automobile recall data from 

Progress: Being finalized for submission.

Essay 3: Vertical spillover effect of automobile recalls 

This empirical essay examines the vertical spillover effect. I theorize that the impact caused by negative events will spread within the supply network due to the cash flow effect and impression effect, and these effects depend on the characteristics of the buyer-supplier relationship and supply network structure.

Related topic 1: Corporate Social Responsibility in Consumer Product Recalls

Although product recalls are a nightmare for the recalling company, the negative consequences of recalls can be mitigated if the firm makes recall decisions that are regarded as socially responsible. This study takes recall remedy to consumers as a proxy of corporate social responsibility of the recalling firm, and examines its antecedents.

Related topic 2: Chief Risk Officer Appointments on Firm Risk and Operational Efficiency 

To exercise risk control at a corporate level, firms often appoint Chief Risk Officers (CROs) into their top management team. By appointing CROs, firms might reduce firm risks and financial losses due to operational disruptions. Yet, by inducing stringent control measures on risks, security, and compliance at different levels, organizations might also create unwieldy bureaucracies with operational hurdles that compromise operational efficiency, leading to paradoxical efficiency outcomes. In this research, we examine how CRO appointments affect firm risk and operational efficiency. We also examine the moderating effects of environmental dynamism and industry litigation threats.

Secondary areas

Research topic 1: Re-evaluating Supply Chain Integration and Firm Performance

This paper is set to provide answers to the following research questions: Does a higher degree of SCI always lead to greater firm performance improvements? As the answer to this question is likely to be no, we explore the performance implications from a strategic perspective: Is the SCI–performance relationship contingent on a company’s competitive priorities (i.e. operations strategy)? We explore the research questions through multiple quasi-independent data sets to test the impact of SCI on firm performance.

Research topic 2: Servitization and Supply Chain Integration

This research examines how supply chain integration moderates the relationship between servitization and performance. Based on the resource-based view and transaction cost economics, we hypothesized the dual effects of supply chain integration in servitization.
