WELCOME TO ENVIRONMENTAL AND MOLECULAR TOXICOLOGY
The integrated mission of the Department of Environmental & Molecular Toxicology (EMT) is to educate students in the toxicological sciences, to conduct research on the effects of chemicals and other agents on humans and the environment and to engage the public through extension and outreach. The EMT Department focuses on creating, disseminating, and applying new knowledge to enhance the treatment and prevention of human disease and to ensure the protection of the environment and public health.

Please Welcome Our New Research Associate Cady Lancaster!
My name is Cady, and I’m excited to join EMT as a Research Associate and Lab Manager in Dr. Manuel Garcia-Jaramillo’s Water Quality Toxicology Lab. My background is in timber metabolomics, with a focus on species identification to support forensic applications. I’ve worked at the Royal Botanic Gardens, Kew (UK), the OSU College of Forestry, and also established a tree-specific forensic lab for the U.S. Forest Service. My work has centered around developing mass spectrometry methods, building sample databases, service provision, and supporting efforts to combat illegal logging. Originally from Oregon, I am glad to be back in Corvallis and at OSU. When I’m not in the lab, I love exploring the outdoors and spend time collecting spruce/pine/fir cones, birdwatching, painting, and embracing my inner naturalist.
Dr. Stacey Harper and Dr. Susanne Brander were recently interviewed for SOT TV on their micro and nanoplastics research.
Siva Kolluri Joins Oregon Cancer Action Day – April 1st “CANCER IS NO JOKE!”
On April 1st, Siva Kolluri joined volunteers from across the state in Salem for Oregon Cancer Action Day, organized by the American Cancer Society Cancer Action Network (ACS CAN). This year’s theme, “Cancer is No Joke!”, underscored the urgency of the cause.
Siva has been an ACS CAN volunteer for the past eight years. During the event, he participated in several meetings to provide information about a key priority for the Oregon chapter of ACS CAN in 2025: better access to biomarker testing. Biomarker testing is a critical step in accessing precision medicine, which allows cancer patients to receive targeted therapies tailored to their unique condition. These treatments can lead to better survival rates and a higher quality of life. Siva spoke about the need for improved coverage of comprehensive biomarker testing in Oregon. He also spoke about the importance of eliminating cost sharing for follow-up cancer screening tests that are needed after an abnormal result. Enabling these tests is essential for early detection and better outcomes.
ACS CAN works to help raise awareness and for policies that support people with cancer, survivors, and those at risk.
David Bugarin Renteria from the Mermer Lab received the 2025 Burlingham Undergraduate Student of Excellence Award in the College of Agricultural Sciences.
The purpose of the award is to recognize outstanding scholastic leadership and achievement in undergraduate students at Oregon State.
From 2022 to 2024, Dr. Diana Rohlman, Dr. Chloe Fender, and Dr. Manuel Garcia-Jaramillo collaborated with the Portland Harbor Community Coalition (PHCC) to conduct a comprehensive study of surface water organic contaminants in the Portland Harbor Superfund Site. For the full story.
Dr. Jennifer Duringer through the Endophyte Service Laboratory collaborated with researchers and Extension agents from the University of Florida, as well as local veterinarians for over seven years evaluating the mycotoxin profile in forage grasses found throughout Florida and associating risks to animal health.
