Hello, my name is Craig Aumack and I am currently a post-doctoral researcher at Lamont-Doherty Earth Observatory of Columbia University. My long term research interests focus on the physiological, biochemical, and ecological adaptations of macro- and microalgae to polar environments as well as their influences on overall community structure. Currently, I am focused on Arctic sea-ice algae populations and how those communities respond to various environmental changes. I am also interested in learning what contributions Arctic sea ice algae have toward the greater near shore Arctic ecosystems and how those contributions may vary in a rapidly changing Arctic environment. Additionally, I have maintained several projects studying the roles of defensive secondary metabolites produced by ecologically important macroalgae in communities along both the western Antarctic Peninsula and the Alaskan Arctic coast. These interactions include predator-prey relationships, epi/endophytic biofouling, allelopathic chemistry relating to interspecific competition, chemical communication, photo-adaptation, and chemotaxis of various invertebrate and macroalgal larvae/spores.
