Four P.I.'s, Petra Lenz (Lab pages) , Ann Castelfranco, Andy Christie and Dan Hartline (Lab pages) , form a collaborative research group with position opportunities from time to time in several areas (email user names in the list below are all "at pbrc dot hawaii dot edu"):
General information: Our research projects cover a range of topics involving the relation between neural mechanisms, behavior and ecology of marine crustaceans, especially calanoid copepods. We currently work on both warm-water species available in Hawaii (including copepods in long-term cultures), and cold water copepod species from the Gulf of Alaska. Approaches include molecular (transcriptomics and bioinformatics), behavioral (high-speed video), respirometric, morphological (immunohistochemistry, confocal and electron microscopy) and electrophysiological ones, applied to problems in population cycles (diapause), predator-prey interactions and other aspects of marine crustacean behavioral and physiological ecology. Some projects extend more broadly to decapod crustaceans of Puget Sound and Gulf of Maine and to insect model systems (Andy Christie).
Mechanics: We accept graduate students through the Graduate Program of the Department of Zoology (Hartline, Lenz), the Oceanography Department (Lenz), and the Marine Biology Program (Lenz). Support on TAships is available (competitively) for incoming Zoology students. Grant support for students working on thesis research needs to be arranged in advance, and inquiry should be made about future prospects when you contact the lab. The Zoology Department grants both Masters and PhD degrees. Application deadline is December 15 of each year (click for application information). We have been able to host a number of internships for graduate students from other universities if they are at least partially supported by the home institution. Some additional stipend support may be available from us depending on our current funding situation. Postdocs may be supported on stipends, if available, and candidates are strongly encouraged to submit applications for their own support in collaboration with one of the faculty here.
Contact: Petra Lenz for general inquiries.
Copepod predator-prey interactions: Currently (2018) winding down) but an area of continuing interest, this project has focused on escape behavior in calanoid copepods responding to attacks by artificial (precise computer controlled) predator mimics and actual fish predators (e.g. clown fish). This project has also involved interaction with Dr. Daisuke Takagi of the UH Math Department. His work involves the mathematics of hydrodynamic flows as they affect biological organisms, including both copepod prey and fish predators in predator-prey interactions. For information, contact Petra Lenz.
Copepod diapause: A project focused on the annual descent by calanid copepods to deep (>400m) waters followed by dormancy during the early winter in the Gulf of Alaska. The aims are to understand the physiology underlying the different phases of preparing for, entering and emerging from dormancy. They involve a combination of transcriptomics, morphometry, respirometry and fluorescent tagging as well as oceanographic cruises with ship-board sampling on the Seward Line and experiments. For information, contact Petra Lenz.
Crustacean myelin A project examining the evolution of myelin in two crustacean taxa, the Malacostraca and the Copepoda. For background, see our Invertebrate Myelin and Myelin Evolution web pages. Current interest is focused on the molecules of invertebrate myelin, using transcriptomic approaches. For information, contact Dan Hartline.
2. Undergraduate Students
We welcome motivated undergraduates interested in hands-on research experience related to the projects in our lab. There are currently five avenues for such experience:
Foreign students: We are open to applications from students in study-abroad programs. Visas and financial support are always an issue, but these problems vary on an individual basis. We have had some success with such programs, but the initial arrangements must usually be made by the student. An EXCELLENT command of written and spoken English is essential.
3. High-school Students
We accept well-qualified high-school students to undertake special projects in our area of expertise, for example related to the Hawaii State Science and Engineering Fair. Prospective students need to present a well-organized plan for the research they would conduct in the lab, including what sort of problem(s) they would like to pursue, how they would go about it and how much time they have to spend on it. Projects should start no later than early fall for March State Science Fair presentations (school and regional fairs are usually January/February).
