Research Interests

Building Chemical Complexity with Sunlight: Spectroscopic Studies of Atmospheric Molecules, Radicals, and Their Complexes. Professor Vaida's research interest focuses on issues of photoreactivity in planetary atmospheres, including the contemporary and ancient Earth. The approach employed to obtain the structure and dynamics of molecules, radicals, and their complexes involves a combination of spectroscopic, photofragment and theoretical techniques. Aqueous environments, especially water-air interfaces as available at the sea surface and on atmospheric aerosols are special reaction environments investigated by surface reflection spectroscopy.

Current Research

Atmospheric Photochemistry of Organic Molecules. Our program explores water- and sunlight-mediated processes in planetary atmospheres including the contemporary and prebiotic Earth. My approach aims to provide new input for models of atmospheric chemistry and climate, using fundamental chemical physics to address complex multiphase chemistry. Current research has used oxoacids in aqueous environments to exemplify the environmental chemistry that generates complex self-assembled organic aggregates. The Earth’s ocean-atmosphere, a sunlight-driven photochemical reactor, is a large and complex system, but has been altered over its existence through both natural and anthropogenic events. In this global reactor, chemistry occurs in all phases, although gas phase chemistry has received the most attention. It has long been established, however, that heterogeneous and multiphase reactions can be extremely important for a fundamental understanding of environmental chemical reactions, which affect chemical processing, air quality, and ultimately visibility, human health, and the planet’s temperature. Starlight provides energy capable of driving planetary processes, which increase a system’s chemical complexity. Starlight-initiated reactions generate high-energy molecules that are precursors to metabolism as it has evolved in life on Earth. Our experiments are designed to investigate the photochemical synthesis and reactivity of such model organic systems under conditions representative of exoplanet Earth analogues, as well as the effect of water on reactivity. Based on this photochemistry, potential spectroscopic probes will be designed for the identification of high-energy species and consequently of potentially habitable environments.

Collaboration within CIRES allowed analysis of the importance of the aqueous phase photolysis of pyruvic acid in the atmosphere. Our laboratory measurements of the rate of the photochemical reaction in solution were used as input for an atmospheric model that compared the loss of pyruvic acid through aqueous photolysis to the loss from the gas-phase photochemistry and oxidative processes. Results indicated that in an acidic environment, the aqueous photolysis is equally as important as the gas-phase photolysis, emphasizing the importance of developing a mechanistic understanding of aqueous-phase photochemical processes.

We have scaled the fundamental experimental work with pyruvic acid to realistic atmospheric conditions by using environmental chamber studies. Specifically we are using the CESAM (French acronym for Experimental Multiphasic Atmospheric Simulation Chamber) at the Université Paris–Est Créteil Val de Marne (UPEC) in collaboration with UPEC Professor Jean-François Doussin. By combining these laboratory and chamber studies, we connect our understanding of the photolysis of pyruvic acid to mechanisms for aerosol nucleation and growth.
