is above a threshold and in an uncoordinated supply chain the retailer transfers the frequency risk onto the supplier. Optimal reinforcement strategy is dependent on the relative level of the frequency and duration of disruptions and is different for the retailer and the supplier. When selecting a supplier, the duration of disruptions is more important than the frequency of disruptions. Given the dissimilar impact of these dimensions in designing effective risk mitigation policies, managers must measure and consider both these components when evaluating suppliers
and instituting mitigation measures.

His research primarily focuses on risk in an operations management context and can be broadly divided into two areas. First, he works on parsimonious modelling of risk in high-dimensional systems using Lévy processes. Second, he studies the impact of risk and risk dependence in operations management problems such as inventory theory, reliability, and the facility location problem. Prior to his doctoral studies, Professor Malladi has worked as a Statistical Analyst for
Fractal Analytics and as an Equity Research Analyst for Centrum Capital. He holds a B. Tech in Mechanical Engineering from Indian Institute of Technology (IIT) Bombay and an MBA from Indian Institute of Management (IIM) Ahmedabad.
