Water quality is impacted by land management practices, industrial and urban development, and climate change. Surface waters are widely used as drinking water sources, food production, and recreational activities. Hence, their quality needs to be continuously monitored. However, current routine monitoring programs are not generally comprehensive, covering only a limited number of known pollutants and emerging contaminants.

Our lab relies on state-of-the-art high-resolution mass spectrometry (HRMS), combining suspect and non-target screening (NTS) to help expand the coverage of current water monitoring strategies. Suspect candidates can be prioritized based on their potential risk (i.e., hazard and exposure) by combining in vitro toxicity data with computational toxicity predictions. We combine this risk-based approach with effects-directed analysis (EDA), for the identification of unknown toxic chemical contaminants in water and their prioritization based on bioactivity and environmental concentrations. In addition, we use targeted and non-targeted mass spectrometry-based metabolomics and lipidomics analyses, combined with genomics techniques, to better understand the impact of contaminants on animals and human health.

Manuel Garcia-Jaramillo began his academic studies with a B.S. in Environmental Sciences from University Pablo de Olavide (2007) with a minor in Biotechnology. His graduate training was first focused on Education. After earning an M.S. in Biology Education, he decided to focus on research, and to pursue an M.S. in Natural Resources and Environmental Sciences (2012) and a Ph.D. in Environmental Agrochemistry (2015) from the University of Seville.

Dr. Garcia-Jaramillo started his postdoctoral training at Oregon State University (OSU) in 2016 at the Linus Pauling Institute, where he became very interested in mass-spectrometry based metabolomics analysis. In 2017 he joined the College of Public Health and Human Sciences at OSU as a Research Associate, and in 2018 the OSU Mass Spectrometry Center as a Project Specialist. The same year, Manuel was awarded a 2-year USDA-NIFA Postdoctoral Fellowship; and, in 2020, a NIH R90 Postdoctoral Fellowship.

In 2021, Dr. Garcia-Jaramillo joined the Department of Environmental and Molecular Toxicology at OSU as part of the 2019 Integrated River Basin Water Quality and Quantity Investment. He is also affiliated with the OSU Environmental Health Sciences Center and with the NUNM's (National University of Natural Medicine) Helfgott Research Institute.
