Dr. Shah has been active in research, design, and analysis  in many areas of mechanical engineering. These include heat transfer, fluid flow, HVAC, refrigeration, plumbing , fire protection, energy conservation, and renewable energy systems.

He is well-known for the development of general predictive techniques for heat transfer during boiling and condensation which are widely used in the industry and are included in most reference books. His other researches include cooling of inlet air for turbines and engines, solar power plants, ice making machines, thermal energy storage, etc. He has numerous publications including research papers and chapters in engineering handbooks. His book "Two-Phase Heat Transfer," published by John Wiley is a valuable resource for researchers and design engineers. It covers a very wide range of topics including boiling, condensation, gas-liquid mixtures, and gas-solid systems.

Dr. Shah has designed HVAC systems for most facilities including power plants, schools, hospitals, laboratories, computer rooms, communication centers, motels, dormitories, apartment houses, etc.Many of them involved analyses and features to minimize energy consumption.

He has been involved with various ASHRAE Technical committees including 1.3, 8.4, and 8.10.  He is a member of the K-13 committee of ASME for Multi-Phase Heat Transfer. He was honored with  the ASHRAE Distinguished Service Award. Dr. Shah has been listed in Who is Who in Engineering, Who is Who in America, American Men & Women of Science, etc.

Dr. Shah obtained BSME degree from Aligarh University in India, MSME from California State University, and PhD from University of Sunderland in UK.

He is presently Director of Engineering Research Associates, a non-profit organization dedicated to developing practically useable solutions to problems and promoting such research.
