​Professor Smith's research is focused upon development and application of remote and in situ sensors in diverse problems of environment and planetary science.

Professor Smith's primary area of research is directed toward the development of a novel method for accurate, precise, and long term atmospheric CO2 measurements as ground truth for the global carbon dioxide sink and source determination that is a key element in the verification of global climate change issues. Second is the development of a non-invasive tree ring determination method to permit rapid, accurate growth rates studies of statistically significant numbers of trees in forests, which are coupled to climate change estimates based on dendrochronology.

He is also developing an ultraviolet LIDAR for profiling of atmospheric transient trace species which key to understanding the temporal and spatial distribution of these species and their relation to urban and non-urban environments and is developing a novel multiplexed and multichannel sensor for visible to far-infrared determinations of regolith composition and nature for solar system bodies, including comets, asteroids, and terrestrial planets.
