Erica Marti

Dr. Erica Marti’s main research interests are in water and wastewater treatment, especially in the area of transforming wastewater for a beneficial reuse (drinking water, irrigation water, etc.). Past work has included understanding the formation of unregulated disinfection byproducts (DBPs) and investigating different methods to prevent their formation. DBPs are created when water is disinfected with chemical oxidants like different forms of chlorine and ozone. We use the chemicals to inactivate pathogens (bacteria, viruses, etc.) but the chemicals can react with other dissolved organics and inorganics to create unwanted byproducts, some of which are toxic. Therefore, water treatment professionals must work carefully to provide the right amount of oxidant for disinfection while minimizing DBPs.
Future research topics include remediation of polluted groundwater, adsorption of heavy metals from wastewater using biochar made from agricultural waste products, uptake of DBPs in plants grown using treated wastewater, and optimizing toxicity assays for DBPs.
Dr. Marti also conducts research in the area of STEM education and has led several Teacher Professional Development programs for integrated STEM lessons and engineering design.

Spencer Steinberg

Spencer Steinberg, Ph.D., is a Professor of Chemistry at the University of Nevada Las Vegas, where he teaches general, analytical and environmental chemistry courses at both undergraduate and graduate levels. Dr. Steinberg has over thirty years of experience in basic and applied research related to the environmental analytical chemistry of the atmosphere, soil and water. His research focuses on quantifying trace organic and inorganic compounds in complex matrices.
Dr. Steinberg’s recent research projects encompass a range of topics which include method development for determination of trace volatile organic compounds in soil and water, detection of silver nanoparticles in water, photochemical formation of oxidants in heterogeneous systems, characterization of natural organic matter in soil and water and the characterization of municipal solid waste. He has also developed ongoing collaborations with various colleges in material science and biology. His research has been funded by the NASA, the US EPA and The US-DOE.
Dr. Steinberg holds a Ph.D. in Marine Chemistry from the University of California, San Diego Scripps Institution of Oceanography.
