Marika Nell

B.S., Civil Engineering, University of Illinois at Urbana-Champaign, 2014
M.S., Civil and Environmental Engineering, Cornell University, 2018 
Research Interests: I work to understand the fate and water quality impacts of chemicals associated with unconventional shale gas development. Thousands of chemicals have been disclosed as fracking additives or produced water constituents and others are unknown because they are proprietary information or wholly unanticipated. I work to detect these chemicals in flowback and produced waters, surface water, and groundwater using broad analytical methods and suspect and non-target screening techniques. These methods enable a more holistic characterization of fracking-related waters. This is important for developing better environmental monitoring, ensuring proper treatment for fracking produced waters, and assessing the risks presented by spills and improper disposal of these produced waters.

Casey Ching

B.S., Environmental Engineering, Lehigh University, 2017
Research Interests: I am interested in improving our understanding of the fate and transport of trace organic contaminants in natural and engineered water systems. I am interested in understanding their transformations and their potential impacts on aquatic ecosystems and human health. My research will focus on developing adsorption-based remediation processes using cyclodextrin polymers to remove per- and polyfluoroalkyl substances (PFASs), a class of trace organics, from impacted groundwater.

Paige Jacob

B.S., Environmental Science, Marist College, 2018
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
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.
