Subbaiah V. Malladi, Ph.D., P.E.
Principal Engineer & Chief Technical Officer
  • Menlo Park

Dr. Malladi obtained his Ph.D. from California Institute of Technology, specializing in the fields of Fluid Mechanics and Heat Transfer. As a mechanical engineer and the firm’s CTO, Dr. Malladi specializes in issues that have societal impact, including extensive experience in the transportation field. He has directed several practices within Exponent, including fluid mechanics, heat transfer, information technology, and environmental services. His experience covers a wide range of applications in engineering and science, including equipment used in transportation systems (such as the fuel, ignition, steering, cooling, braking, electrical and safety systems on vehicles), power plant equipment (such as steam turbines, boilers, furnaces and gas generators), home appliances (including water and air heaters, refrigeration units, and equipment used in washing, drying and cooking), medical equipment (such as catheters and cochlear implants), environmental concerns (such as pesticide sprays, ground water contamination, and atmospheric dispersion), and risk analysis.

He has led several experimental and analytical studies that address multi-phase flows, including analyses of fine sprays. His expertise extends to analyses of large-scale warranty and accident data in the course of his assessment of the real world performance of numerous motor vehicle platforms. Dr. Malladi often directs substantial experimental investigations, including full-scale multi-vehicle automobile crashes, accident reconstructions, product analysis and failure mode evaluations, and burn testing. Because of his education and training in the fields of fluid mechanics and combustion, he also supervises large-scale investigations pertaining to fire cause and origin, automotive fuel system assessment, heat transfer and combustion, and studies involving specialized instrumentation. 

Dr. Malladi has held a variety of research positions including a fellowship at the California Institute of Technology and a Project Leader position with the National Aeronautical Laboratory in India. He also served as a Senior Research Assistant at the Indian Institute of Technology.
