Dr. Cheng-Shiuan Lee is a Senior Research Support Specialist with the CCWT. Dr. Lee holds a Ph.D. in Chemical and Biological Oceanography 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, Dr. Lee 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 compounds) 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 determining trace elements and organic compounds in natural water samples.
