Dr. Murali Mohan specializes in issues related to microbiology, water chemistry, water management, and fate and transport of chemicals in the environment. He also has an extensive understanding of microbial problems and microbial control strategies in the oil and gas sector.

Prior to joining Exponent, Dr. Murali Mohan worked as a Senior Engineer at The Dow Chemical Company as part of the microbial control group. At Dow, he was involved in the design and development of microbial control technologies, specifically for the oil and gas sector. He was also involved in evaluating the commercial and technical aspects of water treatment and microbial control technologies. During this time, he operated as focal point in collaborating with internal and external partners resulting in successful partnerships for technology development. 

Dr. Murali Mohan’s doctoral thesis focused on characterizing microbial communities in flowback and produced water from hydraulic fracturing operations using molecular ecology techniques. He has experience using bioinformatics tools (e.g., Mothur, UniFrac, MG-RAST) for microbial community analysis and equilibrium modeling software (e.g., MINEQL +) for geochemical studies.
