Robert Nelson and Christopher Reddy recognized for pioneering use of GCxGC to track and understand marine pollution

Newswise — Woods Hole, Mass. (February 20, 2026) — Two chemical oceanographers from the Woods Hole Oceanographic Institution (WHOI) are being awarded the 2026 Lifetime Scientific Achievement Award by the International Symposium on Comprehensive Multidimensional Chromatography.

Robert Nelson and Christopher Reddy, both in the Department of Marine Chemistry and Geochemistry, are being recognized for more than 15 years of continuous, high-impact contributions in the field of comprehensive two-dimensional gas chromatography, commonly known as GCxGC

GCxGC is an advanced analytical technique that separates and identifies highly complex mixtures of chemicals with exceptional detail.

With more than 60 years of combined experience, Nelson and Reddy have pioneered the use of this method to analyze pollutants in the ocean, revolutionizing the field of oil-spill forensics. Their work has advanced scientific understanding and informed response strategies for some of the most significant oil spills in recent history, including the 2010 Deepwater Horizon disaster, as well as spills in San Francisco, Massachusetts, Florida, Texas, and California, and internationally in Brazil, Sri Lanka, Mauritius, Korea, and Japan.

“As an oceanographer, I am particularly proud that this award is selected by, and presented to, analytical chemists—a field dedicated to advancing how chemicals are measured,” Reddy said. “It is a tremendous honor to have our work recognized by this community.”

“What is especially meaningful to me is that Chris and I worked so closely together—often on site collecting samples on boats and beaches, analyzing them, and writing about the results,” Nelson added. “This award reflects not just our technical work, but a long-term partnership forged in the field and in the lab.”

The Lifetime Scientific Achievement Award for GCxGC Research is one of the highest honors bestowed by the GCxGC community, recognizing sustained innovation and impact in analytical chemistry and separation science. Nelson and Reddy will receive the award at the44th International Symposium on Capillary Chromatography & 21st GCxGC Symposiumin Riva del Garda, Italy, this spring.

About Woods Hole Oceanographic Institution

The Woods Hole Oceanographic Institution is a private, non-profit organization on Cape Cod, Massachusetts, dedicated to marine research, engineering, and higher education. Established in 1930, its primary mission is to understand the ocean and its interaction with the Earth as a whole, and to communicate an understanding of the ocean’s role in the changing global environment. Top scientists, engineers, and students collaborate on more than 800 concurrent projects worldwide—both above and below the waves—pushing the boundaries of knowledge and possibility.
