I am interested in the mechanisms responsible for the behavior of organic molecules in the environment. The activities in my research group apply both experimental and modeling approaches to elucidate the mechanisms that control the physical and biological fate of these molecules. Our current projects investigate bacterial metabolism of natural organic substrates, interactions of organic contaminants with natural particles, bacterial response to organic contaminants, and nutrient-cycling extracellular enzymes.

Postdoctoral Associate, Biological and Environmental Engineering, 2016-Present
Ph.D. Biogeochemistry, La Trobe University, Australia, 2016
B. Sc. in Environmental Management and Ecology (with Honours), La Trobe University, Australia, 2009
I am currently intrigued by the interactions of organic ligands with mineral substrates at the molecular level, in particular how the stereochemistry changes between the organo-mineral and metal-ligand complexes. My research involves combining spectroscopic and metabolomic techniques, along with molecular modelling, to understand the drivers behind organo-mineral interfacial interactions important in environmental chemistry and environmental engineering processes.

B.S. Natural Resources and Environmental Science, University of Illinois-Urbana Champaign, 2016
I am interested in understanding how the chemistries of microbial and plant organic secretions influence their fate within the soil matrix, with respect to their interactions with minerals. I am particularly interested on how the different fates of these organic molecules affect soil physical properties such as soil moisture retention and soil aggregation.
M.S./Ph.D. Student, Biological and Environmental Engineering, 2016-Present
B.S. Biology, Washington and Jefferson College, 2015
I am interested in cleaning up the environment using bioremediation techniques. I am particularly interested in the mechanisms underlying microbial degradation of plastics in different environmental matrices.
Ph.D. Student, Biological and Environmental Engineering, 2017-Present
B.S. Cell and Molecular Biology, Shahed University, Iran, 2011
M.Sc. Cell and Molecular Biology, Shiraz University, Iran, 2015
I am interested in studying enzyme-catalyzed reactions. Understanding the molecular basis of the enzyme structure-function relationship is required to predict catalytic activities and inform protein engineering. I am currently studying beta-glucosidase, which catalyzes a rate-limiting step in carbon turnover in terrestrial ecosystems and in engineered biofuel production.
Ph.D. Student, Microbiology (Rotation), 2017-Present
B.S. Biology, Cabrini University, 2014
I have a strong interest in bioremediation and biodegradation, specifically looking at how microbes degrade recalcitrant compounds in vitro and in situ. I hope to better understand microbial metabolism and potentially isolate novel microbes that break down anthropogenic pollutants.
Research Technician, Biological and Environmental Engineering, 2017-Present
M.Eng. Biological and Environmental Engineering, Cornell University, 2017
B.Eng. Biotechnology, Sri Jayachamarajendra College of Engineering, Mysore, India, 2016
My current research focus is to study the major metabolic pathways controlling the metabolism of mixed substrates by soil bacteria in response to nutrient-limited conditions. My long-term interest is to solve environmental problems using biological, socio-economical, pollution, and public health perspectives.
