Meet the Lab

Fanny is a PhD student in the department of Civil and Environmental Engineering. Fanny completed her A.S (2013) in Mathematics at Minneapolis College, then her B.S (2015) and M.Eng (2016) in Environmental Engineering at Cornell University. She is interested in the fate and transport of contaminants in environmental matrices and in developing remediation techniques for these contaminants. For her M.Eng study, Fanny investigated the mechanisms governing the trapping of fluoroquinolone antibiotics in montmorillonite clay. Currently, her research focuses on developing new media for stormwater treatment. Fanny hopes to develop effective materials and techniques to be used in the remediation of a broad spectrum of contaminants. In her free time, Fanny enjoys hiking, discovering new places, discovering and listening to new podcasts and watching stand-up comedy. 

Jessica Steigerwald completed her B.S. in Environmental Engineering at Oregon State University in 2018. Her undergraduate research focused on removal of heavy metals (Cu, Pb, and Zn) from stormwater using locally sourced biochar materials. After graduating Jessica began working with Arcadis, a global design and consultancy firm, in Clifton Park, New York as an entry level Environmental Engineer. Her work at Arcadis has focused on remediation of PCBs and organic solvents in soil, groundwater, and surface waters. Jessica is a National Science Foundation Graduate Research Fellow. Her research interests lie in fate and transport, and treatment of aquatic contaminants. In her free time Jessica enjoys running, reading, drawing, traveling, and spending time outdoors.

She is interested in researching the fate and transport of emerging organic contaminants as well as developing materials to treat emerging organic contaminants. In her free time, Alanna enjoys gardening, hiking, biking, soccer, cooking, and listening to podcasts. 

Jen Hooper is a PhD student in in the department of Civil and Environmental Engineering. She competed a BS in Biological Systems Engineering with a minor in Mathematics from the University of Idaho in 2004 and an MS in Environmental Engineering and minor in Risk Analysis, Assessment and Communications from Cornell University in 2006. Since that time she has been a professional engineer in consulting and is currently serving as a Principal at CDM Smith. Her consulting work has focused on chemical and biological treatment processes for remediation, drinking water, wastewater and water reuse, including over a dozen R&D projects for the Water Research Foundation and the Department of Defense’s Environmental Security Technology Certification Program. She is a National Science Foundation Graduate Research Fellow. Her PhD research is investigating degradation of recalcitrant halogenated organic compounds, such as PFAS, by hydrated electron generating photosensitizers including biomolecules, effluent organic matter and natural organic matter. She enjoys going for bike rides, hiking, yoga and quality time with her family. 

Joshua is pursuing a B.S. in Chemical Engineering and learned about water treatment from an Environmental Engineering class taught by Dr. Ray and Fanny. He joined the lab under Nikki in early 2021, helping her test biochar made from spent coffee grounds as a filter media. Now that Nikki has graduated, he continues the coffee ground biochar experiments and is coding in Python as a side project to help with data analysis. In his free time, Joshua enjoys drawing, dancing, performing music, and playing video games with his friends. Though his work involves coffee grounds, his favorite beverage is water.

Joseph (Joe) joined Dr. Ray’s lab during summer 2021 and is pursuing a B.S. in Chemical Engineering with a minor in Data Science. Working under Fanny, his time is focused on the synthesis of ferrate coated sand and testing its efficacy as a means of water treatment. After graduation, Joe hopes to continue his education in a data related area of study, in the meantime, and while he’s not busy with school, he can be found playing D&D or watching tv.

Shawnie is currently in the Chemical Engineering undergraduate program. She developed a strong interest in the AIMS Lab after discovering research, projects, and goals of the lab. Shawnie joined the lab in Fall of 2021, and is assisting Jess Steigerwald’s research on the removal of PFAS in stormwater using biochar. In her free time, Shawnie enjoys traveling, roller skating, and trying new foods and restaurants.

Katya completed her B.S. in Environmental Sciences (2012) and PhD in Environmental Engineering (2017) at the University of California, Berkeley. During her doctoral research, Katya developed an inexpensive process to remediate fluoride-contaminated groundwater by using bauxite, an aluminum-rich ore that is widely available in resource-constrained regions affected by endemic skeletal fluorosis. Currently, Katya is a UW Commercialization Postdoctoral Fellow and the Founder/CEO of her nonprofit, Global Water Labs. Katya aims to scale up and deploy the groundwater defluoridation process in the East African Rift Valley in conjunction with field partners. Katya is also conducting research to treat industrial wastewater containing heavy metals (e.g., Cu, Pb, Zn) at Cascade Designs, Inc. Her overarching research interests are to leverage inexpensive natural composite ores to remediate persistent inorganic groundwater contaminants, to evaluate the efficiency of different reactor configurations, and to develop novel methods for addressing solid waste produced during water treatment by adsorption. In her spare time, Katya loves throwing pottery at the studio, cooking vegetarian meals, playing strategy-based board games, bouldering, playing soccer, and exploring new waterfalls and rivers.

Yuemei completed her Ph. D in the chemistry department in Tongji University in China (2017). During her Ph.D. study, she was focused on the functional polymetric hydrogel synthesis and their applications. Then she worked on functional porous materials design for selective adsorption and desorption of toxic pollutants in water during her postdoctoral research in the University of Wisconsin-Milwaukee in the School of freshwater center. Her research projects were supported by the A.O. Smith Corporation. and SSI Corporation. Currently, Yuemei is a UW Postdoctoral Fellow, she has background on both material science and water treatment research, she is focusing on developing useful and green materials or methods for drinking water and wastewater treatment. She desires to become a professional female scientist, working on environmental applications. In her spare time, Yuemei loves walking outside, enjoy the sunshine, reading books, cooking Chinese food, swimming and exploring the city.

Vivian graduated with her B.S. in Chemical Engineering in 2021. She joined the AIMS lab in the summer of 2020, assisting Dr. Yuemei Ye with the characterization of a nano-material for PFAS degradation. During her senior year, Vivian completed an independent honors research project to investigate molecularly imprinted polymers for selective removal of long and short chain PFAS from water. Outside of the lab, she enjoys spending time in the kitchen, as well as getting outdoors to hiking and backpack. Ultimately, Vivian is looking to pursue a career in science to promote sustainability and combat today’s pressing environmental concerns.

Daaniya first became interested in water treatment while working on a wastewater remediation project as a process engineering intern at Sonoco. Her desire to focus on water treatment applications led to her application to the Global Water Labs, and she looks forward to applying research concepts in a scalable commercial setting. She hopes to gain valuable experience as well as knowledge from her mentors in the AIMS lab over the summer. Daaniya enjoys playing badminton, perusing food blogs, attempting to play the drums, climbing stairs, and writing in her free time.
