Dr. Murphy is an assistant professor in the Department of Fisheries and Wildlife and Lyman Briggs College. She is also an affiliate for the Center for Integrative Toxicology, Center for Water Sciences, the Environmental Science and Public Policy program and the Ecology, Evolutionary Biology and Behavior Program. Her current research focuses on how information collected on an individual translates across higher levels of biological organization. Using fish as a model organism, she explores how changes in gene expression and the physiological processes occurring within an individual translate to behavioral changes and ecologically relevant endpoints such as reproduction and growth, how short term phenotypic changes in expressed traits alter long term genetic change and affect life history traits, and how anthropogenic influences such as contaminants and other stressors impact such relationships and affect populations or communities of fish.

Dr. Murphy is well-versed in various subjects such as reproductive physiology, behavior, ecology, toxicology, and modeling, and can provide links between the different disciplines. Her overall goal is to bridge laboratory work with field sampling and modeling to address issues in environmental toxicology.
