Dr. Neuman has over 35 years of experience in environmental studies. Air quality experience for mobile and stationary sources of air pollutants includes experience with the MOBILE6.2, MOVES2010b, AERMOD, NonRoad, and CAL3QHC/R models. She has monitored and modeled noise levels and mitigation measures for mobile and stationary sources, using the TNM, CadnaA, and RCNM models. In addition, she has monitored and modeled aircraft and rail noise. She has also conducted approximately 100 Phase I ESAs. She has been an expert witness for air quality and noise analyses and has been a guest lecturer on community noise assessment at New York University. Prior to starting Sandstone, she worked at The Berger Group, Urbitran Associates, and Metcalf & Eddy of New York.
