Expert has strong technical knowledge of mechanical and chemical engineering. He specialized in thermodynamics, heat and mass transfer, fluid mechanics, and reaction engineering. He is highly experienced in design of heat exchangers, burners, chemical and bio-reactors, electrochemical systems, and alternative energy systems among others. He was involved in design and analysis of variety of prime movers and advanced power cycles including fuel cells, batteries, internal combustion engines, gas turbines, compressors, and combined heat and power systems. Driven by passion for clean technology and renewable energy, he spent over two decades in that area. He worked for a solar bio-fuels startup, an energy storage company, and at several fuel cell startups, where he was a co-founder of one of them.

He is currently running an engineering consulting firm, which is his third undertaking as a founder/co-founder. His company provides services in many areas of chemical and mechanical engineering and can complement any firm's internal capabilities with mostly PhD level staff. His firm can assist with basic engineering tasks, like mechanical design and drafting, all the way to complex engineering analysis, including CFD and FEA. They also provide help with controls, and have some manufacturing and prototyping capabilities. They are an on-demand engineering resource with a wide range of engineering capabilities.
