Martinović-Weigelt Lab: Research in Environmental Toxicology

September 27, 2016 / By: Dalma Martinović-Weigelt, PH.D.

 

Professional Interests

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.
