Dr. Christopher Gobler is a Professor within the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University.  He received his M.S. and Ph.D. from Stony Brook University in the 1990s.  He began his academic career at Long Island University (LIU) in 1999.  In 2005, he joined Stony Brook University as the Director of Academic Programs for SoMAS on the Stony Brook – Southampton campus.  In 2014, he was appointed as the Associate Dean of Research at SoMAS and in 2015, he was named co-Director for the Center for Clean Water Technology (CCWT).  The major research focus within his group is investigating how anthropogenic activities such as climate change, eutrophication, and the over-harvesting of fisheries alters the natural biogeochemical and/or ecological functioning of coastal ecosystems.   Within this realm, major research efforts include the study of harmful algal blooms (HABs) caused by multiple classes of phytoplankton in diverse ecosystems as well as the effects of coastal ocean acidification on marine life.

Dr. Gobler was born on, and has spent his entire life on, Long Island.  He grew up enjoying swimming on Long Island’s ocean beaches, fishing on the East End, and sailing on the Long Island Sound.  His pursuit of his graduate studies in marine science was motivated by the progressive declines in Long Island’s shellfisheries during the 1980s. During the past twenty years, his research has identified the key role excessive nitrogen loading has played in the degradation of Long Island’s fisheries and water quality.  With the establishment of the CCWT, Dr. Gobler sees the promise of discovering the solutions to Long Island’s nitrogen problems as well as the creation of an industry that can create jobs for Long Islanders.

Ms. Hilary Brooks  serves as the Center's Administrator, responsible for grants management of all Center funding and providing principal administrative support to the Center team. She works collaboratively with numerous campus departments as well as outside partners and stakeholders to ensure the success of the Center's mission. Hilary comes to us with extensive experience in the administrative policies and procedures of Stony Brook University, having previously worked in finance, campus safety, student affairs, and academics. The opportunity to continue to support Stony Brook's mission has kept Hilary with the campus after earning a B.S. from SUNY Empire and an M.A. in Higher Education Administration from Stony Brook University. 

Dr.   Stuart Waugh is a Research Scientist at the CCWT. He received his M.S. (2008) and Ph.D. (2015) degrees in marine chemistry from the School for Marine & Atmospheric Sciences at Stony Brook University. His dissertation entitled “Net N2 fluxes in muddy sediments of Great Peconic Bay: rates, pathways and controls” investigated the sedimentary production of NH4+ and its loss from the sediments as N2 gas as well as the natural and anthropogenic controls on these processes.  At CCWT, Stuart’s research is directed at understanding how septic systems transform fixed nitrogen (NH4+, organic N) into reactive forms (NO3-, NO2- and N2O) and inert gas (N2) and the efficiency with which alternate systems accomplish these processes.

Dr. Cheng-Shiuan Lee is a Research Scientist with the CCWT. His current research focuses on the fate, occurrence, and treatment of emerging contaminants (e.g., 1,4-dioxane, PPCPs, PFAS) in aqueous environments. He also serves as an instrumentation scientist to manage mass spec facilities for the Center. Dr. Lee holds a Ph.D. in Marine Sciences from Stony Brook University (2017) and a M.S. in Chemical Oceanography from the Institute of Oceanography, National Taiwan University (2008). Prior to joining the CCWT, he was a postdoctoral researcher in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University. His Ph.D. and postdoctoral research focused on methylmercury bioaccumulation, transformation, and trophic transfer in marine food webs, ranging from bacterioplankton to apex pelagic fish. Dr. Lee’s research interests include the biogeochemistry of trace elements in natural waters, interactions of contaminants (trace elements and organic pollutants) with aquatic biota and their biogeochemical implications and fates in diverse aquatic environments, distribution and speciation of trace elements and organic compounds in diverse aquatic environments, and developing analytical techniques for the determination of trace elements and organic compounds in natural water samples.
