Interests

I am Distinguished Research Professor of Mathematical Biology UCSC and Director of the Center for Stock Assessment Research (CSTAR), which is a training program, jointly between UCSC and the NOAA Fisheries Laboratory in Santa Cruz, for students and post-doctoral colleagues so that they can learn the quantitative methods needed for ecosystem based fishery management and thus improve the sustainability of fisheries in the U.S. and world-wide. I am also Adjunct Professor in the Theoretical Ecology Group at the University of Bergen, Norway (Visit the TEG), Visiting Professor at the Antarctic Climate and Ecosystems Cooperative Research Center at the University of Tasmania, Australia (Visit the ACE ERC), and a Visiting Scientist at the Puget Sound Institute, Center for Urban Waters, Tacoma, WA (Visit the PSI)

In my first job out of graduate school, I worked for the Operations Evaluation Group (OEG) of the Center for Naval Analyses doing operations research for the Navy (the role model for Kelly McGillis's character in Top Gun was one of my colleagues). I moved to UC Davis in 1980 with the intention of doing OEG-style work, but with applications to fisheries and agriculture. Currently, I am broadly interested in using mathematical methods to solve problems that arise in biology (especially ecology, evolution, and behavior) and believe that we all should be working in what Donald Stokes called Pasteur's Quadrant of use-inspired basic research: where a search for fundamental understanding is motivated by an important applied problem. Stokes's book Pasteur's Quadrant. Basic Science and Technological Innovation (Brookings Institution Press 1997) is well worth reading

My interests and that of my research group are currently:

Quantitative Methods for Sustainable Fishery Management : We are developing the tools that will be needed to make Ecosystem Based Fishery Management (EBFM) a practicable approach for fishery management in the 21st century. Some of our recent projects include:

- The implications of climate change for southern ocean krill, their predators, and the management of krill fisheries (PhD thesis of John Wiedenmann, post-doctoral work by Kate Cresswell, and current PhD work of Kate Richerson).

- An integrated program of field work, laboratory work, and modeling to understand how water temperature and food availability affect the growth, survival, and migratory tendencies of steelhead trout, with application to water management policy in California (post-doctoral work of Will Satterthwaite and David Swank, support for graduate students Chris Simon and Anand Patil, and current work of PhD student Juan Lopez on the Carmel River).

- A study of the evolutionary origins and fishery management implications of the reproductive biology of fishes (with NOAA Fisheries colleagues Jon Brodziak, EJ Dick, and Alec MacCall)

One of my students, Teresa Ish, was the co-founder of FishWise (Visit FishWise) and the developer of the FishWise program, which trains point of sale people in aspects of sustainable fisheries. I am a Charter Member of the Board of Directors and was Organizational Incubator/mentor and continue on the BoD. FishWise is an example of social entrepreneurship, in which the strategies and tactics of business are used to solve imporant social problems and to thus create social value. FishWise recently signed an agreement to train Safeway employees about sustainability (Press release ) There is already a spin-off from FishWise, FishChoice (Visit FishChoice) which does the same kind of work for commercial buyers of seafood, rather than consumers

With Steve Munch, NOAA Fisheries, and a team consisting of Santiago Salinas (post-doctoral scholar), Simon Brown (graduate student) and Jo Anne Siskidis (technician), I am investigating transgenerationmal thermal plasticity in a small fish. In brief this phenomenon is this: these fish have a growth rate versus temperature profile that has a peak (temperatures that are either too cold or too warm are poor for growth). If a mom experiences an off-peak temperature for a sufficiently long time, her offspring emerge with their temperature-growth rate peaking not at mom's but at the off-peak temperature that mom experienced.

With NOAA Fisheries colleague Jon Brodziak and long time collaborator Michael Bonsall (University of Oxford), I am investigating the application of ideas from information theory to population dynamics.

I gave the inaugural webinar for the NOAA Fisheries Quantitative Ecology and Socioeconomics Training (QUEST) Program. My topic was `A Perspective on Steepness and Its Implications for Fisheries Management'; get it here

"Whaling in the Antarctic: Australia v. Japan. New Zealand Intervening": Between July 2010 and July 2013, I served as the Independent Scientific Expert of Australia for this case in the International Court of Justice (ICJ), concerning whether the Japanese special permit whaling program is for purposes of scientific research or not. The other two scientific experts were Dr. Nick Gales, Chief Scientist of the Australian Antarctic Division (Australia) and Professor Lars Walløe, University of Oslo and President of the Academia Europaea (Japan). At the ICJ website for this case you can find Australia's original filing (under Application),the written proceedings, which include the Memorial of Australia, the Counter-Memorial of Japan, the Intervention by New Zealand, and the Expert statements and associated correspondence (under Written Proceedings), transcripts of the hearings (under Oral Proceedings), and Orders and Press Releases by the Court. The hearings are available as a recorded webcast (VOD) on the United Nations Web TV TV website. My testimony at the Court can be found about an hour into this link.

Although I expect to write a number of papers about this case, I have not yet done so. To make things a bit easier for interested readers here are my Original Report in the Memorial of Australia, my my Supplementary Report in light of the Counter Memorial of Japan, my Response to the Expert Statement of Professor Walløe (which can be found at the Court web-site), the Expert Statement of Nick Gales, and the Response of Nick Gales to the statement of Professor Walløe.

Sidney Holt, one of the founders of modern fisheries science and a member of the Committee of Three who advised the IWC in the 1960s, wrote a blog about the case, which he has allowed me to post, for purposes of information.

Our Approach to Mathematical Biology My research group is unified by the tools we use: models (differential equations, stochastic dynamic programming and Bayesian statistical methods), experiments (either here in Santa Cruz or in collaboration with colleagues elsewhere) and field observations. We apply these ideas to a variety of systems, currently including southern ocean krill, steelhead trout, Pacific rockfish, stem cell systems (particularly the blood system and planaria). Although I worked for many years on insect parasitoids and tephritid fruit flies, we are not doing much with them just now.
