Dr. Casalnuovo is a chemical engineer in Exponent's Thermal Sciences Practice specializing in the sampling and analysis of gases and aerosol particles. He has expertise in measurement of atmospheric pollutants, gas‑phase kinetics, development of analytical techniques, and design of gas‑phase flow reactors. Dr. Casalnuovo's experience with building experimental systems and his background in mass transfer, kinetics, and thermodynamics enable him to analyze and explain complex engineering problems.

Dr. Casalnuovo earned his Ph.D. in Chemical Engineering from Carnegie Mellon University, where his research focused on the measurement, transport, and kinetics of trace atmospheric gases and aerosol particles affecting global radiative forcing. As part of his doctoral work, he planned and executed field measurement campaigns in rural and urban environments, integrating real-world measurements with Gaussian plume and trajectory models to investigate pollutant sources, chemical transformations, and fates.

He has experience operating analytical instruments such as chemical ionization mass spectrometers (CIMS), condensation particle counters (CPC), scanning mobility particle sizers (SMPS), aerosol particle sizers (APS), trace gas monitors, X‑ray photoelectron spectrometers (XPS), and X‑ray fluorescence (XRF) spectrometers. He has also developed instrumentation techniques for detecting trace concentrations of reactive gases in remote environments.
