Steven Sesma has over a decade of experience as a research associate and chemist. Additionally, at TERC’s Tahoe Center for Environmental Sciences (TCES) and Tahoe City Field Station (TCFS) he serves as the facilities’ Department Safety Coordinator. With a background in Environmental Science & Ecology, Steven was an integral part in researching invasive Asian clam populations within Lake Tahoe and assisted in the design and implementation of experiments to manage several invasive species. Steven uses chemical analyses to study lake and stream water, soil nutrients, phytoplankton, periphyton, and metaphyton. He developed laboratory methods to study micro plastics in the environment. 

“My goal at TERC is to devote myself in providing the world a better quality of life through the sciences,” Steven says. He is excited to be part of an organization that leads the way in research on water quality, physical processes, and lake ecology. He believes in the importance of the work he does and how it supports policy decisions at Lake Tahoe and research efforts at other lakes.
