Lal's current research concerns the opportunities and challenges in building a Business around Smart Connected products/IOT.

He has written extensively on the impact of using the Internet as a channel of distribution on a retailer's pricing, merchandising, and branding strategy.

He has also studied the consequences of grocery retailers’ increasing use of store brands on store loyalty and its implications for packaged goods manufacturers.

The work on salesforce compensation plans originated with his dissertation research, which won the award for the best paper published in Marketing Science and Management Science in 1985. A subsequent article, also developed from his thesis, received an honorable mention for the same award in 1986. He has also studied  compensation plans used by German salesforces.
