Rick Relyea

RICK RELYEA is Director of the Jefferson Project at Lake George for Rensselaer Polytechnic Institute, a groundbreaking partnership between Rensselaer, IBM, and the FUND for Lake George. For the project, Relyea leads a team of Rensselaer scientists, engineers, computer scientists, and other experts who are using the latest in science and technology to understand, predict and enable a resilient ecosystem for nearby Lake George.
 
From 1999 to 2014, Relyea was at the University of Pittsburgh. In 2005, he was named the Chancellor’s Distinguished Researcher and in 2014 he received the Tina and David Bellet Award for Teaching Excellence. From 2007-2014, Relyea served as the director of the university’s field station, the Pymatuning Laboratory of Ecology, where he oversaw a diverse set of ecological field courses and facilitates researchers from around the world.
 
Rick has taught thousands of undergraduate students in introductory ecology, behavioral ecology, and evolution. His research is recognized throughout the world and has been published in Ecology, Ecology Letters, American Naturalist, PNAS, and other leading ecological journals. The research spans a wide range of ecological and evolutionary topics including animal behavior, sexual selection, ecotoxicology, disease ecology, phenotypic plasticity, community ecology, ecosystem ecology, and landscape ecology. Currently Relyea’s research focuses on aquatic habitats and the diversity of species that live in these ecosystems.

William F. Ruddiman

William F.  Ruddiman was initially trained as a marine geologist. His subsequent work over many years has explored several different aspects of the field of paleoclimate. His earliest research was on orbital-scale changes in North Atlantic sediments to reconstruct past sea-surface temperatures and to quantify the deposition of ice-rafted debris. He also studied the way that vertical mixing by sea-floor organisms smoothes deep-sea climatic records. Later, his interests turned to the cause of long-term cooling over the last 50 million years. This research led to a new hypothesis that uplift of the Tibetan Plateau has been a major driver of that cooling, with Maureen Raymo's work on chemical weathering a central part of that hypothesis. That research also demonstrated that Tibetan uplift created much of the seasonally alternating monsoon climate that dominates eastern Asia today. Since entering 'semi-retirement' in 2001, Ruddiman's research has concentrated on the climatic role farmers played during the last several thousand years by clearing land, raising livestock, and irrigating rice padis. This research produced the 'early anthropogenic hypothesis' --- the idea that early agriculturalists caused an anomalous reversal in natural declines of atmospheric CO2 7000 years ago and CH4 5000 years ago. His research on this issue has been NSF-funded for several years. Because this hypothesis has been very controversial, it has provoked many studies seeking ways to test it.
