Division Officers and Committees

Division Chair 

 

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.

 

 

 

Past Division Chair 

 

 

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.

 

 

 

Program Chair 

 
Nadine Kabengi is an assistant professor of Geochemistry at Georgia State University where she holds joint appointments at the Geosciences and Chemistry departments. Her research involves measuring the energetics and thermodynamic properties of surface reactions,  focusing on mineral-water interfaces and surface reactivity.  She was elected as Program-Chair elect in 2017 and will assume her role in 2018. In her free time, she enjoys binge-watching TV and internet series.
 
 

 

Program Chair Elect

 

 

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.

 

 

Treasurer and Awards Committee Chair

 

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.

Secretary 

 

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.

Councilor

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.

 
James Kubicki was the Program Chair-Elect/Program Chair/Chair in the division in 2004-2006. His current research involves modeling mineral-water interfaces, cellulose and plant cell wall components, and nanoparticle surface reactivity. His favorite geomaterial is soot or black carbon because it is so disorganized.
 
 

Alternate Councilor 


 
Louise Criscenti is a scientist at Sandia National Laboratories using molecular modeling techniques to address geochemical and chemo-mechanical questions relevant to shale gas extraction, carbon dioxide sequestration, nuclear waste glass dissolution, metal adsorption to oxides, and ion disposition in nanopores.  She has served in the volunteer position of Membership Chair (2005-2006; 2011-2012), and in the elected position of Secretary (2006-2008; 2012-2014) for the Geochemistry Division.  She is now the Alternate Councilor (2017-2019).  In her free time, she enjoys gardening, seeing new places, and reading science fiction.
 
 
 

 

Membership Chair

 

 

Hang Deng is a postdoctoral researcher at Lawrence Berkeley National Laboratory, and her research focuses on reactive transport modeling.

 

 

 

Webmaster

 

 

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.

  

 

Newsletter Editor

 

 

Omanjana Goswami is a graduate student at Rutgers University-Newark, majoring in environmental sciences. She works with Dr. Ashaki Rouff and studies the metal-mineral interaction in natural and engineered wastewater environments.

 

 

Newsletter Editor 

 

Dr. Yandi Hu is an Assistant Professor at University of Houston. Her research utilized advanced nanoscale interfacial characterization techniques to probe reactions at solid-liquid interfaces, as applied to better understand mineral nucleation and growth which are related to the fate and transport of aqueous contaminants and scale formation in many natural and engineered systems.  Dr. Hu has been a member of American Chemical Society since 2009.

Social Media Coordinator 

Jessica Rimsza is a postdoctoral researcher at Sandia National Laboratory investing the chemical-mechanical mechanisms which control fracture of silicates using atomistic simulations.
