Martin Krkosek (martin.krkosek@utoronto.ca ) Google Scholar Profile
I am an assistant professor and Sloan Fellow in Ocean Science in the Department of Ecology and Evolutionary Biology at the University of Toronto. I work on fundamental and applied questions in population ecology in the areas of conservation, disease, aquaculture, and fisheries. I work mostly on wet species such as salmon, herring, marine mammals, parasitic copepods, and waterfleas (plus their parasites). We have a long-term fieldwork program on salmon epidemiology and ecology based out of Salmon Coast Field Station and in partnership with the Hakai Institute. I am an editor for the journals Proc R Soc B and CJFAS.


Andrew Bateman (Postdoc, UofT & UofA)
I am a Postdoc working with Mark Lewis (Centre for Mathematical Biology at Alberta) and MK on the ecology and epidemiology of Pacific salmon. Prior to joining the CMB and EEB, I completed my PhD on the population dynamics of cooperative breeders (Meerkats) in Africa with Tim Clutton-Brock at Cambridge. Before that, I completed degrees in Mathematics and Biology at UVic, where I worked with Brad Anholt on sex ratios in copepods and also spent a summer with MK as a research assistant on models and fieldwork on salmon and sea lice. See my webpage.


Pepijn Luijckx (Postdoc, UofT)
I joined MK's lab to work on experimental epidemiology that tests mathematical models of disease spread using waterfleas (Daphnia) and their parasites. Previously I did my PhD with Dieter Ebert at the University of Basel were I focused on host-parasite coevolution and also with Aneil Argrawal at UofT on the evolution of sex. I am now a MEOPAR postdoctoral fellow developing a spatial mathematical model for disease spread in coastal marine ecosystems. For more information on my research visit my website.

Knut Vollset (Postdoc, UofT & Norway)
I am a post doc at Uni Research - Environment, working on the NFR project BaseLice, through which I am collaborating with MK on setting mathematical population models to elucidate the effect of salmon lice on marine survival salmon. My background is from recruitment biology of marine fish, more specifically focusing on behavior ecology fish larvae (PhD, University of Bergen). For the last 5 years I have been working mostly on studying different anthropogenic effects on salmon populations including effects of river regulations and fish farming. For more information see my webpage.
Stephanie Peacock (Postdoc, UofA and UofT)
I am a Postdoc working with Mark Lewis and MK. My research interests include mathematical biology and marine ecology. I did my PhD with Lewis and Krkosek on the population dynamics of sea lice and salmon on the west coast of British Columbia, Canada. For my postdoc, I am working on salmon and sea lice, to extend and complete modeling projects that I began as side projects during my PhD. I have worked on salmon-related projects for various organizations, and am based part time at the Salmon Coast Field Station.

Stefan Meyer (PhD student, Otago)
I am a PhD student supervised by MK and Bruce Robertson at the University of Otago and Louise Chilvers at the New Zealand Department of Conservation. My PhD thesis encompasses population modeling and conservation of New Zealand sea lions. I graduated in biology at the Institute for Environmental Research at RWTH Aachen University, Germany. At that time, my study about the regeneration of Brazil’s Atlantic rainforest strengthened my interest in population dynamics and human induced disturbances. Thus I appreciate being able to work in MK’s lab and increase my skills in population modeling. Additionally I work as a researcher for nature and wildlife history documentaries and also enjoy surfing in Dunedin.

Devin Kirk (PhD student, UofT)
I am a MSc student working with MK at the University of Toronto.  I completed my undergraduate studies at SFU in Vancouver, where I carried out an undergrad research project looking at chemical communication and behaviour in black widow spiders.  My PhD project focuses on experimental epidemiology and modeling, using Daphnia-parasite systems to determine how thermal dependence predicted by the metabolic theory of ecology mediates and host density threshold effects in disease dynamics.
Sean Godwin (PhD student, SFU)
I am a PhD student at SFU working with Larry Dill, John Reynolds, and MK studying salmon disease and conservation.  I completed my undergrad degree at McGill during which time I worked at the Salmon Coast Field Station with MK for three summers in varying capacities, including sea lice monitoring of wild juvenile Pacific salmon for the Broughton Archipelago Monitoring Plan. For my PhD work, I am focussed on how sea lice and viruses affect the fitness of juvenile Sockeye salmon. This entails fieldwork and experiments based at Salmon Coast Field Station, including running a miniature purse seining operation to collect sockeye salmon smolts. Check out my website for more about my research.
Melissa Orobko (MSc student, UofT)
I am a MSc student working with MK and Peter Molnar at the University of Toronto. I did my BSc at SFU, through which I discovered my passion for applied quantitative ecology. My main research focus is using mathematical modelling as a tool to understand what drives population dynamics of threatened species in the hopes of improving conservation management. My honours thesis involved working with Bernie Roitberg in developing a theoretical model to understand how extreme temperatures affect community dynamics. For my Master's thesis I am working on alternate stable states in fishery and aquaculture systems.​

After a childhhood spent on farms Otago and Southland I completed my undergraduate degree in Agricultural Science at Melbourne University and spent the next 20 years travelling and teaching Science, Agriculture, and Environmental studies. Now I am now a PhD student at the University of Western Australia.
Christoph Meyer (Summer Internship, Otago, 2012)
I was a visiting student on a summer research project with MK at Otago in 2012 working on the bioeconomic interactions of fisheries and aquaculture. My research involved building a bioeconomic model to examine how negative externalities from farmed fish on natural populations affects the overall market for fish. I am currently pursuing a master's degree at Rice University in Civil and Environmental Engineering, following my degree in Mathematical Economics from Rice. I am interested in the intersection between economics/business and the environment, particularly in terms of energy, natural resources, and conservation. I enjoy surfing, snowboarding, hiking, photography, and food. 
Anja Studer (Postdoc, Otago, 2012)
I was a Postdoc working with Robert Poulin and MK on temperature sensitivity and landscape structure of a marine host-parasite system: trematodes in New Zealand mudflats. Prior to that I completed my PhD with Robert Poulin at Otago working with the same cockle-trematode system. For the postdoc project, I surveyed intertidal mudflats across the full latitudinal gradient across north and south islands of New Zealand to evaluate if temperature is associated with parasitism levels, as predicted by lab experiments.
Michel Widmann (MSc Intern, Otago, 2012)
I visited MK in 2012 as an MSc Intern from the University de Lyon, France, to work with MK on a climate change and parasitism project in collaboration also with Anja Studer and Robert Poulin. Anja and I surveyed intertidal mudflats across the full latitudinal gradient across north and south islands of New Zealand to evaluate if temperature is associated with parasitism levels, as predicted by lab experiments.
Malcolm McNeil (Honours Student, Otago, 2010-11)
I completed my Honours in the Fisheries and Aquaculture program supervised by Dr. Candida Savage and MK. My honours research focussed on light sensitivities of exploited fishes in order to improve selectivity of fishing gear. Previously, I have worked in the fishing industry as a deep-sea skipper and Vessel Manager along side scientists, government officials and eNGO’s in an effort to reduce seabird by-catch and to develop a sustainable Antarctic Toothfish fishery in the Ross Sea. These interactions led to a desire to gain a better understanding of the science behind the decision making processes that lead to environmentally sustainable seafood production.

Anthea Ibell (Research Assistant, 2010-11)
I worked as a research assistant in the lab helping to maintain large datasets on salmon spawner-recruitment as well as parasite abundance on wild juvenile Pacific salmon. Currently, I have taken a break from my BSc at Otago because I was awarded the Austral-Asia Rolex Our World Underwater Scholarship! This will fund me for a year of SCUBA diving work to contribute to marine biology exploration, research and education projects around the world. I am interested in marine biology, conservation and both paleoarchaeology and archaeozoology. I enjoy SCUBA diving, travelling and generally exploring outdoors.
