"I believe microorganisms are the best chemists in the world"
Microbial processes can inspire us to develop new pollutant clean up solutions, helps us become more resilient to climate change disasters, and be powerful environmental health indicators. The very complex issues of pollution and climate change disasters require all of our perspectives, which is why our lab combines all of our strengths, from analytical chemistry and microbiology to data science.
"My research journey has taken me finding joy in bench-scale microcosms, small worlds, to study how microorganisms adapt to pollution from nitroaromatics to forever chemicals, as well as wading and chasing storms after forest fires to evaluate water quality. The best part of it all is to get to do this work with my students and colleagues. Water always makes me happy, whether is swimming in it or painting it. "
Donghui Ma
Ph.D. student in the Department of Civil and Environmental Engineering at the University of California, Irvine. Her research focuses on the interactions between per- and polyfluoroalkyl substances (PFAS) and microorganisms, including microbial biotransformation of PFAS, microbial enzymes capable of PFAS degradation, and microbial responses to PFAS-induced stress. Prior to joining UCI, she earned her master’s degree from the Research Center for Eco-Environmental Sciences at the Chinese Academy of Sciences and her bachelor’s degree from Xiamen University. Her master’s research investigated the prenatal mother-to-infant transfer and metabolic degradation behavior of PFAS.

Allison Tilzey (she/her)
Ph.D. student in the Department of Civil and Environmental Engineering at UCI. Her research interests include wet chemistry, WUI fires, and water quality. She has assisted in collecting and analyzing environmental samples from Aliso Creek after the 2022 Coastal Fire and presented preliminary findings at UCI's Spring 2023 UROP Symposium in collaboration with Maya El Ajouz.
She has participated in on campus tutoring initiatives through the Learning and Academic Resources Center, as well as on campus engineering clubs such as Global Engineering Brigades and ASCE. In her free time she likes to read, spend time with friends, or go on hikes.

Lyssa Morgan
Ph.D. Candidate in the Civil and Environmental Engineering department. Her research interests are in studying microbes and processes involved in biotransformation/bioremediation of industrial and environmental contaminants. Prior to her start at UCI she completed her master’s degree in Synthetic Biology and Biotechnology at the University of Edinburgh and a bachelor’s degree in Biotechnology at Cal Poly Pomona. Her masters thesis involved research into biochar mediated bioaugmentation of a hydrocarbonoclastic consortia of microorganisms for improved bioremediation of hydrocarbon contaminated sediment.

Audrey Pellico
Ph.D. student in the department of Civil and Environmental Engineering here at UCI. Her research interests included environmental chemistry along with bioremediation from solid and hazardous waste. Currently in the Olivares lab, Audrey is investigating the biotransformation pathways of PFAS precursors through co-metabolism. She believes it is important to understand the reactions with enzymes and the natural environment in order to be able to prevent and clean up PFAS contaminated sites. Audrey’s hobbies include running, soccer, hanging with her friends and watching the WNBA.
Ann Hsu
Master’s Student at UC Irvine majoring in environmental engineering. Her interest is in PFAS sensing technology. She is currently working on understanding the fluorophilic interaction between different classes of PFAS and engineered β‑CD. Prior to starting the Master’s program at UC Irvine, she completed her bachelor’s degree in environmental engineering at UC Irvine. She is also an intern at Orange County Sanitation District. In her free time, she enjoys spending time outdoors, hanging out with family and friends, and trying new food.
Fourth-year undergraduate at UCI, studying Environmental Engineering and minoring in Earth & Atmospheric Sciences, with an aim to pursue energy sciences and engineering as a master’s program. Previously studying connections between climate change and PFAS distribution with Jialin Dong, they are now assisting Allison Tilzey with observing microbial activity on differing water samples. Other involvements at UC Irvine include serving as President for the Society for Hispanic Professional Engineers and two years on the Environmental Design Construction Team for the American Society of Civil Engineers.
In their free time, Nicolas enjoys extending their Duolingo streak, reading historical nonfiction, and day trips around Southern California.
Michelle is a fourth-year environmental engineering undergraduate student. She is currently conducting an independent research project for the Honors Collegium, in which native California plants are used in the remediation of soils contaminated with lead in the city of Santa Ana. She also currently works as an undergraduate research assistant in UCI’s Environmental Processes Lab, examining the fate and removal of microplastics in wastewater treatment processes. She is a Water Quality Technician for the ASCE Environmental Design Team, and her research interests include the fate and remediation of environmental contaminants.
Senior undergraduate at UC Irvine majoring in Environmental Engineering and minoring in Digital Information Systems. Under the mentorship of Lyssa Morgan, she is currently working on extracting and purifying PFAS from paper and textile materials for quantitative LC-MS analysis. She is also a board member on the ASCE Environmental Design Team as Co-Assistant Construction Captain.
Tania Barajas
Second-year Civil Engineering student at the University of California, Irvine. She is passionate about creating a more sustainable future through innovative structural design and research. As the Lab Manager for the Olivares Lab, she contributes to a community with environmental responsibility.
Beyond the lab, Tania is an intern board member for the external affairs in the Society of Hispanic Professional Engineers (SHPE). She works to uplift and empower her community. She believes in the strength of collaboration and is dedicated to helping Latinos thrive in STEM and make a positive impact on the world “, because together, we stand.”
