Paige Jacob

B.S., Environmental Science, Marist College, 2018
M.S., Civil and Environmental Engineering, Cornell University, 2021

Research Interests: I am interested in understanding the effects of anthropogenic contaminants on water quality and how this impacts human and ecosystem health. Specifically, I am intrigued by the biotransformation of trace organic contaminants found in wastewater systems. My research will focus on characterizing per- and polyfluoroalkyl substances (PFASs) found in wastewater systems and evaluating the fate and transport of PFASs in these systems.

Stephanie Rich

B.S., Environmental Engineering, Oregon State University, 2015
M.S., Water Science and Engineering, Karlsruhe Institute for Technology, 2018
M.S., Civil and Environmental Engineering, Cornell University, 2022

Research Interests:  I am interested in improving environmental water quality by utilizing microbiological processes in wastewater treatment plants to reduce anthropogenic emissions. My research aims to advance the understanding of micropollutant biotransformations performed by wastewater microbial communities for the development of more cost-effective and energy-efficient wastewater treatment strategies. I am especially interested in the interactions of wastewater microorganisms with their environment at a metabolic level and how they are linked to operational parameters in wastewater treatment plants.

Nayantara Joseph

B.S., Environmental Engineering, Drexel University, 2019

Research Interests:  I am broadly interested in environmental contaminant management and remediation- specifically of anthropogenic contaminants in natural water systems. My research will focus on using machine learning tools to develop unique chemical signatures that can be used to identify the source and possible environmental transformations of per- and polyfluoroalkyl substances (PFASs) at various contamination sites. This will allow for rapid identification and differentiation of PFAS sources and possible resulting transformation compounds allowing for more informed remediation decisions for a specific site.
