In this project - in collaboration with Dr. Joy Waite-Cusic in the Department of Food Science and Technology and Dr. Tyler Radniecki in Environmental Engineering at OSU - we investigate enteric antibiotic-resistant bacteria and genes from wastewater to agricultural soil and food crops. The overall objective of this project is to identify the abundance and diversity of antibiotic resistance in wastewater and biosolids across different seasonal and regional variations, and to further determine the impact of the application of wastewater and biosolids on growth and dissemination of antibiotic-resistant bacteria and genes in soils and on vegetable crops. This project received seed funding from OSU Agricultural Research Foundation Competitive Grant, and is funded by USDA National Institute of Food and Agriculture.

This project, in collaboration with Dr. Gerrad Jones in the Department of Biological Engineering, investigates the chemical composition and microbial communities of wastewater in different biological treatments and biosolids. Machine learning algorithms, high-resolution mass spectrometry, chemical forensics, and high-throughput sequencing are used to develop chemical fingerprints and determine the association between chemical transformations and microbial communities.
In this project - in collaboration with Dr. Susanne Brander in the Department of Fisheries, Wildlife, and Conservation Sciences and Dr. Stacey Harper in the Department of Environmental and Molecular Toxicology/Environmental Engineering at OSU - we aim to understand the fate, transport, and effects of microplastics in wastewater and receiving environments. We anticipate identifying the impact of secondary vs. tertiary wastewater treatment on the microplastics in treated biosolids as well as the occurrence and abundance of microplastics in biosolids amended soils and associated run-offs. This project is funded by the Agricultural Research Foundation.
This project is a collaboration with Dr. Tyler Radniecki in Environmental Engineering at OSU. We aim to determine the impact of stormwater pretreatment with biochar before irrigation at reducing antimicrobial resistance on food crops.
This project is a collaborative interdisciplinary work with Dr. Goran Jovanovic and OSU’s Advanced Technology and Manufacturing Institute (ATAMI). In this project we investigate the application of photolytic treatment in a novel micro-scale reactor for the inactivation of fecal indicator organisms in drinking water.
This project was in collaboration with Dr. Mi Nguyen at Nguyen Tat Thanh University in Vietnam. The purpose of the study was to identify the human health risks associated with the spread of infectious bacteria resistant to antibiotics in areas with high septic tank use. Findings are published in the Environmental Science and Pollution Research journal:
This project funded by REACH Catalyst grant explored the relationship between arsenic contamination, antibiotic-resistant bacteria in the gut, and health. It focuses on two vulnerable groups – women and children – living in areas with and without water insecurity due to arsenic contamination. This study was in collaboration with Mohammad Aminul Islam (icddr’b, Bangladesh), Timothy R. Julian (Eawag, Switzerland), Anisur Rahman (icddr’b, Bangladesh), Zahid Hayat Mahmud (icddr’b, Bangladesh), Molly Kile (PHHS, OSU), Karen Levy (Emory University), Catherine Mattioli (Emory University). Findings were published in Frontiers in Environmental Microbiligy. A systematic review paper was on this topic is published in the special issue of Frontiers in Science and Engineering "Environmental Antibiotics and Antibiotic Resistance":
