I conduct research that explores how fish respond to natural environmental stimuli (e.g., fluctuations in the oxygen concentrations, stream velocities), as well as to man-made stressors (e.g., chemicals of emerging concern in particular). To determine how fish adapt to and are perturbed by environmental stimuli I combine classic physiological and organismal endpoints (swimming performance, reproductive success, behavior). I am also using functional genomics and systems biology to complement approaches conventionally used for study of the physiological basis of behavior and reproductive toxicology.

Dalma Martinović-Weigelt completed Ph.D. in Fisheries Science and Water Resources at the U of MN (2005), and served as National Academies Research Associate at the U.S. Environmental Protection Agency (US EPA) from 2006-09. Dr. Martinovic is an associate professor at UST, St. Paul, MN (2009-present). Dr. Martinovic has co-authored two reports to MN Legislature (Endocrine Disrupting Compounds, lrp-ei-1syo8; Wastewater Treatment Plant Endocrine Disrupting Chemical Monitoring Study, lrp-ei-1sy11) and circa 40 research manuscripts that assess occurrence and the effects of chemicals of emerging concern and other stressors on fish and aquatic ecosystems. Dr. Martinovic is a recipient of five US EPA’s Scientific and Technological Achievement Awards. She has served on The Contaminant Screening Criteria and Prioritization Development Task Group for MN Dept. of Health, and the Editorial Board of the Environmental Toxicology and Chemistry Journal. Since her arrival to UST in 2009Dr. Martinović-Weigelt has received external-funding from a variety of state and federal agencies (MN Pollution Control Agency, USGS, USEPA and NSF).
