Dr. Pradeep Ramasubramanian specializes in providing engineering solutions for indoor and outdoor air pollution problems. He has extensive experience in studying indoor air, specifically indoor heterogeneous and homogeneous chemistry and indoor particle and aerosol dynamics as well as experience in understanding urban pollutant fate and transport.

He has worked with mass spectrometers (PTR-TOF-MS, GC-MS), high-frequency anemometers, high-frequency open-path scalar analyzers, UV absorption-based ozone monitors, optical particle sizers (OPS) as well as condensation particle counters (CPC). Dr. Ramasubramanian is keenly interested in quantifying exposure to gas-phase pollutants, coarse and fine particulate matter, as well as virus/bacteria-laden aerosols. Aside from his indoor and outdoor air quality related work, he is also experienced with product design and development, including sheet metal fabrication, injection molding, and PCB/PCA enclosures.

Prior to joining Exponent, Dr. Ramasubramanian earned his doctorate in mechanical engineering at Portland State University, where he studied the effectiveness of air pollution mitigation systems on indoor occupants. His research focused on analyzing ozone mitigation mechanisms in the built environment, from in-situ measurements of ozone deposition to urban greenery and green roofs to modelled effectiveness of ozone mitigation methods applied at the breathing zone scale. In addition to his research on air pollution mitigation methods at PSU, Dr. Ramasubramanian contributed his expertise to projects involving multifractal analysis of variable density jets, liquid bridge break-up during zero-g pipetting, and human VOC characterization for improving human trafficking detection. 

Dr. Ramasubramanian has worked as a design engineer with expertise in new product design and development. He has designed for and tested with firearms and has experience with the various failure modes of firearms. He also has experience in designing and testing wood and natural gas fired ovens and rotisseries for industrial kitchen applications as well as designing for plastic flow, injection molding, and PCB/PCA enclosures.
