Ph.D research conducted at the Bodega Marine Laboratory ResearchMy studies are concerned with the role of hormones in regulating physiological processes in decapod Crustacea (crabs and lobsters). Hormones are chemical mediators that regulate physiological processes such as growth, reproduction, and osmoregulation. I am interested in the mechanism by which hormones such as ecdysteroids, methyl farnesoate, and molt-inhibiting hormone regulate growth and reproduction in decapod crustaceans. The majority of crustaceans that I study are commercially important crabs. These include Dungeness crab, Cancer magister, snow crab, Chionoecetes opilio, and king crab, Paralithodes camtschaticus. Ecdysteroids are crustacean hormones that function to regulate the molt cycle and therefore the growth of these animals. Methyl farnesoate is a sesquiterpenoid hormone derived from the mandibular organ that functions in both reproduction and growth. Methyl farnesoate also may be critical during crustacean larval development and morphogenesis. Methyl farnesoate is structurally similar to the insect juvenile hormones, which regulate insect development. Other studies related to crustacean physiology involve the effect of endogenous crustacean hormones on ectoparasites. Specifically, I have an interest in how hormones (ecdysteroids, methyl farnesoate) can be exploited by certain parasites. The model for these studies is the infection of the Dungeness crab, Cancer magister by the nemertean worm, Carcinonemertes errans. Courses Taught

ResearchMy general interests are in evolution, ecology, and conservation biology. My focus is on understanding the evolutionary and ecological dynamics of natural populations using demographic and genetic models, molecular genetic data, and field data. I have long-standing interest in combining population genomics and demographic information to infer important evolutionary and demographic parameters for wild populations. More recently, my post-docs and I have focused upon the role of phenotypic plasticity in adaptation. I have used models based on likelihood and approximate Bayesian computation to infer demographic vital rates or effective population size with the goal of providing useful results and tools for conservation and evolutionary biology. As an example, some collaborators and I have recently developed an approach to infer effective size of a population using a single sample of microsatellite data and approximate Bayesian computation. We focus on a number of different taxa in my lab, with current work on a handful of terrestrial and marine vertebrates and invertebrates, including: coastrange sculpins, giant Pacific octopus, red king crab, spruce grouse, file dogwinkles, ringed seals and boreal toads. I enjoy working with students who are highly-motivated, broadly interested in evolution and conservation, and focused on understanding population-level process using descriptive and manipulative approaches.

ResearchHow does natural selection maintain phenotypic variation within marine species? What role do ecological interactions like predation and competition play? My research interests are broadly concerned with these questions. More specifically, I investigate (1) how ecological interactions in the ocean orchestrate relationships between form, function, and fitness, (2) the ecofunctional implications of bilateral asymmetries, and (3) the impact glacial melt-water has on estuarine fish communities. I explore these topics with a variety of techniques, including morphometrics and behavioral observations, field experiments, multivariate statistics, stable isotope analyses, and experimental assessment of fitness. I currently have two main research projects underway. The first of these is the evolution of body asymmetry in flatfish. Flatfish exhibit remarkably derived body morphology. They undergo metamorphosis as pelagic larvae, where one eye migrates over the dorsal midline so that both eyes are on the same side of the head, and they lie on the ocean floor, eyed-side facing up. While the vast majority of the 715 flatfish species contain all left-eyed or all right-eyed individuals, 7 species contain both morphs. To date, we don't have a good understanding of the evolutionary trajectory flatfish took to become asymmetric, or the significance of asymmetry direction. One polymorphic species, the starry flounder, exhibits a cline in the north Pacific in the relative frequency of left- vs. right-eyed individuals, and the two morphs show evidence of ecological segregation. It is one of the first demonstrations of the ecological significance of polymorphism in a marine species, and contributes to our understanding how asymmetry evolved across the flatfish order. My second current research project involves how glacial melt water affects fish living in estuaries. Glacial estuaries differ in habitat characteristics from rain-fed estuaries, including temperature, sediment composition, turbidity, and water chemistry. In a collaborative project funded by EPSCoR Alaska and Alaska Sea Grant, we are comparing community structure of fishes found across estuaries that differ in their glacial influence. Differences in these communities will inform predictions of how marine fishes will respond to predicted increases in melting rate of glaciers that flow into our oceans. Courses Taught

Biology University of St. Joseph (Focus: Human Biology) 2008 Special Recognition:UA President’s Award for Outstanding Distance Educator in Alaska (2001) Courses TaughtBIOL 111 Human Anatomy & Physiology I Past Courses Taught:Microbiology, Natural History of Alaska, Intertidal Biology, General Biology, Biology & Society, BiographyI’m originally from Northern California and lived in Bethel and Skagway before moving to Sitka in 1992. I enjoy helping students build a firm foundation in the topic that will serve them well in their careers. I am active in the Human Anatomy and Physiology Society (HAPS). As part of HAPS I helped develop standards for undergraduate human anatomy and physiology courses taught in the US and Canada. I am committed to quality eLearning opportunities and developed and delivered the first distance science courses offered by UAS. As Sitka’s lab director I currently help oversee the lab support portion of UAS Sitka Distance Science courses which have grown to involve multiple faculty members and currently serve over 200 students each semester. I believe it is important to give back to my community by doing what I can to enrich science literacy, assist in community-based scientific research, and help create science-related opportunities for everyone, especially K-12 students. Community Projects:
I am particularly interested in the ecology and functional anatomy of intertidal organisms, especially with respect to predator-prey relationships. I am also very involved in marine invasive issues and research, particularly with respect to invasive tunicates. I am a member of the Alaska Marine Invasive Species subcommittee and the Didemnum vexillum Rapid Response Team. | |
