William (Bill) Burgos is a professor of environmental engineering in the Department of Civil and Environmental Engineering at the Pennsylvania State University. His research focuses on the biogeochemistry of metals and radionuclides, the bioremediation of organic contaminants, and water management associated with shale gas development.
Anastasia Ilgen is a staff scientist at Sandia National Laboratories. She is an experimental geochemist, specializing in molecular-level processes at mineral-water interfaces, with emphasis on ion adsorption-desorption rate and mechanisms, chemical controls on mineral growth and dissolution, and surface-mediated redox reactions. She volunteered with the Division since 2013, and became a Chair-Elect in 2015.
Dr. Ashaki Rouff is an Associate Professor of Geochemistry at Rutgers University, Newark NJ. Her research uses laboratory-based model systems, field work, and advanced molecular-scale techniques; as applied to the areas of contaminant geochemistry, urban geochemistry and sustainable geochemistry. Dr. Rouff has been a member of the Geochemistry Division and an American Chemical Society member since 2002.
Sebastien Kerisit received his PhD in computational chemistry from the University of Bath and is now a Senior Research Scientist at the Pacific Northwest National Laboratory. His research interests cover a wide range of topics relevant to the geochemistry community including the chemistry of mineral-water interfaces, carbon capture and sequestration, the aqueous corrosion of glasses, the mechanisms of mineral nucleation and growth, and the redox properties of natural systems. Sebastien has been a member of the ACS and the Geochemistry Division since 2006. He recently served a four-year rotation as Program Chair-Elect (2013), Program Chair (2014), Division Chair (2015), and Past Division Chair (2016) of the Geochemistry Division. Most recently, Sebastien served as Chair of the Geochemistry Division Medal Committee.
Sang Soo Lee is a staff scientist at Argonne National Laboratory. His research focuses on in situ and real-time observations of molecular-scale processes at mineral–water interfaces in geochemical systems primarily using synchrotron-based X-ray scattering and spectroscopic techniques. He has been an ACS member since 2010, and has served as the Membership Chair (2015-2017) for the ACS GEOC division. He is now the Secretary (2018-2020) for the division.
James Kubicki is a professor and chair in Geological Sciences at the University of Texas at El Paso working on computational chemistry of environmentally relevant reactions. He just started as the Councilor for the division in 2016. In his free time, he enjoys ironing and listening to Weird Al.
Jacquelyn (Jacky) Bracco is a postdoctoral researcher at Argonne National Laboratory studying the structure and reactivity of barite using atomic force microscopy and x-ray reflectivity. She has been the assistant webmaster/webmaster for the division since 2013. In her free time, she enjoys gardening, yoga, and hiking.
