Principal Investigator: Dr. Zhenyu Tian

Dr. Zhenyu Tian (he/him) is an environmental chemist curious about organic pollutants in the environment. He received his Ph.D. from the University of North Carolina, where he studied the transformation products and co-occurring pollutants of PAHs in contaminated soil. Then he worked as a postdoctoral research scientist at the Center for Urban Waters, University of Washington Tacoma, applying non-target screening to identify emerging contaminants in water and biota and to evaluate engineered treatment systems. With the research group, he identified 6PPD-quinone, a ubiquitous tire rubber chemical that kills coho salmon via urban stormwater.

Dr. Tian is an Assistant Professor in the Department of Chemistry and Chemical Biology.  He is also affiliated with the Department of Marine and Environmental Sciences and the Barnett Institute for Chemical and Biological Analysis.   

Doctoral Students

Madison H. McMinn (she/her)

Ph.D. Candidate, Chemistry

Read More

Madison H. McMinn graduated summa cum laude from Southern Illinois University Carbondale in 2019, receiving a B.S. in Chemistry with minors in Mathematics and Forensic Science.  During her undergraduate, Madison conducted research into the mechanism of ionization in MALDI-MS under Dr. Mary and Dr. Gary Kinsel.  In the summer of 2018, she was selected as a Harvard-Amgen Scholar, which allowed her the opportunity to conduct research in MALDI-MS Imaging at Harvard Medical School.  As a senior undergraduate student, Madison received the prestigious National Science Foundation Graduate Research Fellowship to pursue her Ph.D. in Chemistry at Northeastern University.

Madison’s research interests include the development of novel chromatography and mass spectrometry methods with applications in environmental chemistry, as well as the development of data analytics programs to aid researchers in compound identification from complex mixtures.

In her free time, Madison enjoys baking, playing video games, and spending time with her Siamese cat, Vitruvius.

Kat Poisson (she/her)

Ph.D. Student, Chemistry

Phillip Berger (he/him)

Ph.D. Student, Chemistry

Read More

Phillip graduated from Sewanee with a B.Sc. in Chemistry in 2019. He worked on the Trace Metals Analytics Lab within Discovery Sciences at RTI International in RTP, NC, performing high throughput analysis of water samples for toxic contaminants such as lead. During his time at RTI, he was awarded an internal research grant to investigate water soluble organic pollutants in PM2.5 collected during wildfires in conjunction with Dr. Imari Walker-Franklin and the Ions Analytics Lab.

Phillip’s research is centered on method development utilizing the QuEChERS method, with future avenues looking at contaminants in a number of matrices. In his free time, Phillip enjoys cooking, video games, and playing with his cats.
