Young-Shin Jun is the Division Chair of the American Chemical Society’s Geochemistry Division, after serving as the Program Chair-Elect (2014) and Program Chair (2015) of Geochemistry Division. Her research group aims at improving our understanding of the fate and transport of contaminants and nanoparticles, providing more environmentally sustainable CO2 sequestration strategies, and elucidating physicochemical reaction mechanisms occurring in water treatment processes.
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.
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.
Lisa Stillings is a low temperature geochemist who studies element cycles in the earth's crust. Her interests range from weathering kinetics, to trace metals, to Li brines and clays. She has served as the GEOC secretary, 2009-2011, and is now the GEOC treasurer, 2014-2016. In her free time she hikes/trail runs w her dogs, gardens, and sings with the Reno Philharmonic Chorus.
Yoko Furukawa is an Associate Director at Office of Naval Research Global. Prior to joining ONRG in 2014, she worked as a sediment geochemist at Naval Research Laboratory (NRL) at Stennis Space Center, Mississippi, USA for 20 years.
Yoko currently serves as the Alternate Councilor for American Chemical Society Division of Geochemistry. She is the Co-Editor in Chief for the Division's official journal, Geochemical Transactions. She has served for the Division since 2002, as the Chair (2006), Program Chair (2005), Program Chair (2002-2004) and Treasurer (2008-2010).
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.
