His research interests are the determination of the chemical composition and molecular structure of compounds that reside in sea-surface films; measurement of the range of surface elasticities that occur in coastal, continental shelf, and open ocean environments; development of systems for observing chemical constituents and their enrichments in sea-surface films; study of the effects of biogenically derived surfactant compounds on gas exchange rates at the air-sea interface.

Christopher M. Reddy, Woods Hole Oceanographic Institution, Woods Hole MA, USA
Dr. Christopher Reddy received his B.S. in chemistry from Rhode Island College in 1992 and his Ph.D. in chemical oceanography from the University of Rhode Island in 1997. He is currently an Associate Scientist in the Marine Chemistry and Geochemistry Department at the Woods Hole Oceanographic Institution, one of the world's premier centers for oceanographic research. Dr. Reddy's research focuses on investigating the source, transport, and fate of organic contaminants in coastal and oceanic waters; developing new analytical techniques for studying environmental chemistry; and chemical ecology. He has more than 60 research publications and received an award from the Office of Naval Research Young Investigator Program in 2003. More recently, he was named a 2006 Aldo Leopold Leadership Fellow, which provides training to select scientists so that they can communicate science more effectively to the general public, media, and policy makers.

Stephen E. Reichenbach, University of Nebraska – Lincoln, Lincoln NE, USA
Professor Stephen E. Reichenbach earned a Ph.D. in computer science from the College of William and Mary (1989), a master's degree in computer science from Washington University in St. Louis (1985), and a bachelor's degree in English from the University of Nebraska (1976). He is a professor of Computer Science and Engineering (CSE) Department at the University of Nebraska – Lincoln (UNL), where he has been on the faculty since 1990 and served as department chairman from 1996–2000. He held a National Research Council research associateship in the Visual Information Processing Laboratory at the NASA Langley Research Center and an ASEE research fellowship in the Landsat 7 Project Science Office. He has authored more than 100 technical articles on digital image processing and image information systems. In 1994, Dr. Reichenbach founded Internet Nebraska Corporation, the oldest and largest Nebraska-based Internet service provider. In 2003, Dr. Reichenbach founded GC Image, LLC, to develop advanced informatics software for comprehensive two-dimensional gas chromatography (GCxGC).

John V. Seeley, Oakland University
John V. Seeley is an Associate Professor of Chemistry at Oakland University in Rochester, MI. He received a bachelor of science degree in chemistry from Central Michigan University in 1989 and a Ph.D. in physical chemistry from the Massachusetts Institute of Technology in 1994. He then did three years of post-doctoral research at the United States Air Force Geophysics Laboratory. He joined the faculty of Oakland University in 1997. His research group develops new techniques for characterizing complex mixtures of organic compounds. Over the past six years they have focused on comprehensive two-dimensional gas chromatography (GC x GC). Professor Seeley's research group has created a series of flow-switching modulators that allow GC x GC separations to be generated without the need of additional consumables or high-cost equipment. They have applied flow-switching GC x GC to a multitude of scientific problems including the study of atmospheric chemistry, the evaluation of breath analysis as a tool for non-invasive disease detection, and the rapid characterization of petrochemical mixtures.
