Ph.D. Students

Leenia Mukhopadhyay

I am an environmental chemist with an MS in chemistry from NIT Jamshedpur, India. Currently, I am a first year Ph.D. student at Stony Brook University. My previous work involved the synthesis of nanoparticles with the aim of catalytically degrading organic pollutant dyes in wastewater. I am interested in the fate of organic pollutants in the environment and am working on extracting and quantifying per and polyfluoroalkyl substances (PFASs) in marine animals. Outside of working at the lab, I enjoy badminton, hiking and hanging out with my dog, Rocket!




David A. Dukes

David is an environmental engineer with a background in geochemistry. David has a MS in geology from Temple University where he helped develop a method using rare earth element tracers to quantify aeolian transportation rates. He has also spent time working in environmental remediation, addressing contaminated sites throughout New Jersey. David’s current research is focused on the bioaccumulation and metabolites of per and polyfluoroalkyl substances (PFASs) present in aqueous film forming foams.

Rachel Smolinski

Rachel is a PhD student in the SoMAS department at Stony Brook. She received her BS in chemistry at the University at Buffalo, where she studied inorganic synthesis of alternative MRI contrast agents. Rachel is interested in the fate, transformation, and persistence of organic contaminants in marine and groundwater environments. She is affiliated with the New York State Center for Clean Water Technology at Stony Brook and is currently using high resolution mass spectrometry to identify trace organic contaminants in domestic wastewater and their transformation products in Nitrogen Removing Biofilters.


Master’s Students

Jennifer Marciano

I am a Master’s student in the Department of Civil Engineering at Stony Brook University. I received my BS in chemistry from Stony Brook where I completed research projects related to climate trends as well as landfill remediation. My current research is centered around analyzing per- and polyfluoroalkyl substances (PFASs) in biological systems. Some past and ongoing projects include using high resolution mass spectrometry for targeted screening of PFASs in serum, muscle tissue, and urine, and non-targeted screening in serum. Outside of science, I enjoy playing sports and going to the beach!

Undergraduate Students

Adrienne Popescu

I am a senior undergraduate at the SBU Honors College majoring in Applied Math with a minor in Environmental Studies on the pre-med track. I’m interested in the effects of climate change and environmental contaminants on global public health. After college, I plan to study epidemiology before applying to medical school. Outside of school, I’m an EMT, avid hiker, and violinist in the University Orchestra.

Group Lead

Dr. Carrie McDonough – Assistant Professor of Chemistry

I am a chemical oceanographer and analytical chemist working at the intersection of environmental analytical chemistry, environmental health engineering, and toxicology. I received my B.Sc. in Chemistry from the Massachusetts Institute of Technology (MIT) in 2008, and my Ph.D. in Chemical Oceanography from the University of Rhode Island Graduate School of Oceanography (URI GSO) in 2017. I completed a postdoctoral fellowship at Colorado School of Mines, where I developed methods for nontarget analysis of per/polyfluoroalkyl substances (PFASs) in biological fluids. I use cutting-edge environmental monitoring and analytical chemistry techniques to study the fate, transport, and biological effects of anthropogenic organic contaminants in aquatic environments. Broadly, I am interested in how the molecular structure and chemical properties of pollutants influence their fate in the environment, as well as their biological effects in aquatic organisms and humans. My overarching objective is to understand human and ecosystem health risk associated with organic contaminants in water and to identify particular compounds of concern that should be prioritized for remediation and toxicological investigation. When I’m not working, I am usually brewing beer and hanging out with my dogs, Millie (pictured here) and Pickles.
