Hans-Otto Pörtner, Keynote Speaker

Hans-Otto Pörtner

Hans-O. Pörtner studied at Münster and Düsseldorf Universities where he received his PhD in animal physiology. As a research and then Heisenberg fellow of the German Research Council he worked at Dalhousie and Acadia Universities, Nova Scotia, Canada, and at the Lovelace Medical Foundation, Albuquerque, NM. Currently he is professor and head of the Department of Integrative Ecophysiology at the Alfred Wegener Institute for Marine and Polar Research, Bremerhaven, Germany. He acts as an associate editor in physiology for Marine Biology and as a co-editor of the Journal of Thermal Biology. He was Honorary International Associate Member of the Society for Integrative Biology, USA, between 2006 and 2013. Until the end of 2014 he served as a coordinating lead author of IPCC WGII AR5, chapter 6, Ocean Systems, and as a member of the author teams for the WGII Summary for Policymakers and Technical Summary, as well as a member of the core writing team for the IPCC AR5 Synthesis Report. In October 2015 he was elected co-chair of Working Group II of the IPCC. His research interests include the effects of climate warming, ocean acidification, and hypoxia on marine animals and ecosystems with a focus on the links between ecological, physiological, biochemical, and molecular mechanisms limiting tolerance and shaping biogeography and ecosystem functioning.

Anna Neuheimer, Invited Speaker

Hans-Otto Pörtner

Anna Neuheimer is an assistant professor in the Department of Oceanography at the University of Hawai’i at Mānoa. Anna moved to Hawai’i after work in Canada (Dalhousie University), Australia (CSIRO), and Denmark (Aarhus University and the University of Copenhagen). Anna’s research focuses on designing tools (empirical and mathematical) to explain variability in distribution, connectivity, abundance, size and/or life-history of zooplankton and fish. While work includes low-latitude species (e.g., Hawaiian reef fish), much of Anna’s research is focused on wide-ranging species of the north, with colleagues in Canada, Denmark, and Norway.

Brad Seibel, Invited Speaker

Brad Seibel

Brad Seibel’s research employs a unique suite of field and laboratory techniques and approaches to assess the ecological consequences of climate change, including ocean acidification, deoxygenation and warming, and the role of animal energetics in ecosystem dynamics. He carries out broad comparative physiology studies to determine the limits to evolution and ecology. Physiological mechanism provides a foundation upon which ecosystem responses to climate change and consequences for biogeochemical cycles can be understood. His studies compare organisms across size, depth, latitudinal and phylogenetic lines, from microzooplankton to macronekton, ctenophores to fishes, from the poles to the equator and from the abyssal plains to the ocean surface. Brad strives to integrate across levels of organization, from mitochondria to ecosystems. He focuses on the physiology of individual species and what this can teach us about their origin, behavior, ecology, diversity and the ecosystems in which they live.

Charles Stock, Invited Speaker

Charles Stock

Charles Stock is an oceanographer at NOAA’s Geophysical Fluid Dynamics Laboratory. His research focuses on the development of global Earth System Models (ESMs), and collaborative application of climate and earth system models to marine resource science and management. These applications span time-scales from seasons to centuries, and spatial scales from the global ocean to estuaries. He received his PhD from the Woods Hole/MIT Joint Program in Oceanography and Engineering. In 2010, Stock received the Presidential Early Career Award for Scientists and Engineers for innovative research at the frontiers of climate and ecosystem science.

Cody Szuwalski, Invited Speaker

Brad Seibel

Cody Szuwalski is a research faculty member at the University of California, Santa Barbara, in the Sustainable Fisheries Group within the Bren School of Environmental Management and Science. His research focuses on understanding the dynamics of exploited marine populations and ecosystems, developing models to simulate these dynamics, and evaluating the impacts of changes in management in these systems under uncertainty (e.g., climate change, trophic interactions, or life history). Geographically, his research is currently split between China (e.g., projecting the benefits of management reform using ecosystem models) and Alaska (e.g., performing stock assessments for Bering Sea crab stocks and management strategy evaluations under climate change scenarios).

Kathy Mills, Invited Speaker

Hans-Otto Pörtner

Dr. Katherine Mills is an associate research scientist at the Gulf of Maine Research Institute in Portland, Maine. As a quantitative fisheries ecologist, Kathy has studied ecosystem change and fish-ecosystem relationships in the Gulf of Maine region for over a decade. Her recent work investigates the direct and secondary impacts of environmental variability and climate change on resource populations, biological communities, and marine fisheries. Much of her work is interdisciplinary, seeking to understand and inform management of fisheries as coupled social-ecological systems. Climate adaptation within marine fisheries has become a major recent focus, with emphases on assessing climate adaptation strategies and providing new forms of information to support adaptation planning by fishery participants, fishing communities, and fishery managers.
