Dr. Andrew Stack, Staff Scientist (Geochemistry), Oak Ridge National Laboratory. On Tuesday, at 4 PM in Deike 022, Dr. Stack presents "Mineral Precipitation Reactions from the Atomic - to Pore - Scales." A pre-talk Coffee & Cookies Speaker Reception takes place at 3:45 PM in the EMS Museum on the ground floor of Deike. All are welcome.
Research Interests and Activities
Dr. Stack's expertise is in geology, chemistry and computing to advance the understanding of the dynamics of minerals underground. He investigates chemical processes that take place on mineral surfaces at scales ranging from individual atoms to entire rocks. These processes can trap contaminants, such as nuclear waste, carbon dioxide and toxic by-products from hydraulic fracturing. Fundamental knowledge of chemical transformations is crucial to many Department of Energy missions and serves as a basis for developing ways to lessen the environmental impacts of energy use. The discoveries made by Dr. Stack and his group at Oak Ridge will help to improve geologic storage of carbon dioxide and remediation of toxic contaminants. Prior to joining Oak Ridge, Dr. Stack served as a researcher at the University of California at Davis and as an Assistant Professor at the Georgia Institute of Technology. He is a member of the American Chemical Society and the Geochemical Society.

The Geosc Colloquium Speaker on Tuesday, September 29nd, 2015, is Dr. Donald Suarez, Director of the USDA-ARS Salinity Lab in Riverside, California. On Tuesday, at 4 PM in Deike 022, Dr. Suarez presents "Using a Chemical Surface Complexation Model to Predict Subsurface Oxyanion Transport: B Case Study." A pre-talk Coffee & Cookies Speaker Reception takes place at 3:45 PM in the EMS Museum on the ground floor of Deike. Our faculty hosts for Dr. Suarez are Lee Kump and Sue Brantley.
Ph.D., Geochemistry, Penn State University
B.A., Geology, State University of New York at Binghamton
Research Interests, Activities, and Awards
Dr. Suarez' research interests include the chemistry and management of saline and sodic soils, plant response to ion composition of irrigation water, effects of chemistry on soil physical properties, and modeling water and ion transport in soil, including trace elements. He has served on the editorial board of various journals and was awarded Fellow of Soil Science Society of America and Fellow of the American Society of Agronomy. He is also a member of the Board of Directors of the Soil Society of America. In 2009, he was honored as the ARS Distinguished Senior Scientist of the Year for his scientific leadership and discoveries in effective water resource management. ARS is the principal intramural scientific research agency for the USDA. Dr. Suarez has written over 250 research publications and has co-organized three International Salinity Forums.
In September 2015, Dr. Suarez was named, along with three other scientist, to the ARS Science Hall of Fame. “The extraordinary contributions of these four scientists have had a significant impact on food and agriculture worldwide,” said ARS Administrator Chavonda Jacobs-Young. “Their outstanding accomplishments demonstrate commitment, knowledge and perseverance and exemplify the values that have made ARS the premier agricultural research organization that it is today.”
