Professor Whang's research interest is in supply chain management and the economics of information systems. He studied how demand information may be distorted in a supply chain, and what impacts a secondary market (where retailers exchange excess inventories) has on a supply chain. He has also addressed various pricing issues in a congestion-prone facility. For example, he studied the optimal priority prices in a queueing system where users have their private information about the benefit, time value and service requirement. Recently, he analyzed the menu of fixed-up-to tariffs structure commonly used for mobile phone service and studied how demand uncertainty affects the retailer's dynamic priciing strategy.

Padmanabhan (1997), was elected to be one of the “top ten most influential” papers in Management Science in its 50 years of publications history. Also, his paper "Optimal Incentive-Compatible Priority Pricing for the M/M/1 Queue," coauthored with Haim Mendelson (1990), was the 7th most-cited paper among the papers published in Operations Research between 1952 and Aug. 2012. During 2006-2008 he served as senior editor to Information Systems Research.
