Biography: 

My general areas of interest are marine ecology and ichthyology, and more specifically resource utilization, life history, and fisheries studies of demersal and benthic elasmobranchs (i.e., sharks, skates, and rays) and teleost groundfishes. I am especially interested in trophic ecology and spatial associations of marine fish assemblages, and have several such research projects underway or recently completed between the Bering Sea and Gulf of California. I also have considerable experience in seafloor mapping, collection and analysis of biological and physical data, and trophic and spatial analysis of groundfishes and benthic invertebrates. I enjoy collaborating with colleagues and pursuing interdisciplinary studies. I have especially valued my collaborations with marine geologists, as knowledge of the geologic conditions that create and maintain seafloor habitats for benthic fishes is fundamental to my research.

 

Research Interests:
  • Marine Ecology and Ichthyology
  • Resource utilization, life history, and fisheries studies of demersal and benthic elasmobranchs (i.e., sharks, skates, and rays) and teleost groundfishes
  • Trophic ecology and spatial associations of marine fish assemblages
