Dr. Portnoy is currently an Associate Professor in Marine Biology and the Ruth A. Campbell Professor of Marine Biology in the Department of Life Sciences. I run the Marine Genomics Lab where we use cutting edge, next-generation sequencing technology to address issues of marine conservation and management of exploited marine species. In addition, we investigate biogeography and phylogenetics, with a focus on taxa found in the Gulf of Mexico. The techniques developed and utilized in our laboratory allow us to study population structure at an unprecedented resolution and to characterize adaptive aspects of genomic variation important for persistence at local scales and adaptation to temporal environmental fluctuations.
Conservation genetics of exploited marine fishes, historical patterns of zoogeography, systematics and evolution of bony fishes and elasmobranchs, patterns of sexual selection, conflict and speciation.
