He has held Postdoctoral Researcher positions in South Korea and the United States. At Yonsei University, he contributed to microbial CO₂ fixation systems for organic acid biosynthesis, resulting in a patented process. At the University of Maryland, his work focused on the low-cost production of biopolymers using halophilic microorganisms, where he developed a water-based downstream recovery process that eliminated the need for chemical or mechanical cell disruption. For these contributions, he was honored with the Outstanding Postdoctoral Researcher Award in 2023.

Currently, Naresh is a Postdoctoral Associate in the Stephanopoulos Lab at MIT, where he develops scalable microbial fermentation processes (precise fermentation) for the production of value-added compounds. His work emphasizes bioreactor optimization, critical process parameter control, and downstream integration to support industrial-scale implementation.

Previously, at Green Plains Inc., he led the development of a two-stage microbial fermentation process, significantly improving batch performance and supporting the transition from laboratory to manufacturing environments within a GMP-compliant framework.
