Seung Soo Lee (Steve) is a postdoctoral researcher in the Fortner group and he has joined the lab in Yale University since August, 2021. Steve graduated from Chung-Ang University in South Korea with a B.S. (2004) in Chemistry, and with a M.S. (2007) in Inorganic Chemistry. He received a M.A. (2010) in Chemistry and a Ph.D. (2013) in Chemistry from Rice University with a dissertation entitled “Synthesis and design of nanocrystalline metal oxides for applications in carbon nanotube growth and antioxidants” under the guidance of Prof. Vicki L. Colvin in the department of chemistry at Rice University. After graduation, he started working with Prof. John D. Fortner in the department of energy, environmental & chemical engineering at Washington University in St. Louis as a postdoctoral research associate from 2013 to 2016. With his long term experience in metal oxides, Steve took an industrial job offer from Sensient Technologies in St. Louis, MO and worked as an innovation scientist. During his industrial practical experience, he led the research team to develop/commercialize production scale iron oxide particles as food drug and cosmetic color ingredients from 2016 to 2021. In Yale University, Steve is focusing on synthesis (scale-up), characterization, and environmental application of metal oxide nanocrystals (iron oxide, manganese oxide, cerium oxide, titanium oxide, cobalt oxide, manganese iron oxide, and cobalt iron oxide) encapsulated in surface coatings (e.g., silica, amino acids, fatty acids, and polymer complex shells) and graphene oxide conjugated metal oxide composites. He is also working on new material development for PFAS sorption/separation/decomposition applications.
