Stephanie Green (PI)

Canada Research Chair, Aquatic Global Change Ecology & Conservation 

IMG_20170824_174241I study the causes and consequences of biodiversity change in aquatic ecosystems, with the goal of developing science-based tools to inform conservation and restoration decision-making under global change. As a scientist, I relish the opportunity to spans spaces: developing projects that bridge concepts and scales of investigation, and fostering relationships between people as they work to affect change. As a result, my interests are broad, ranging from simulation models of predator-prey interactions and food webs, to experiments investigating community assembly and resilience, to coupled social-ecological modeling examining behaviour change. The common theme across my work is advancing ecological theory in service of society. Prior to joining the University of Alberta, I was a Banting Fellow at the Center for Ocean Solutions at Stanford University and a David H. Smith Conservation Research Fellow at Oregon State University.

Postdoctoral Fellows


Miram Gleiber

OSTRICH_headshotI am a biological oceanographer and plankton/larval fish ecologist interested in marine food web interactions and how they are influenced by environmental variability. I am working with the Green Lab on a project investigating the role of prey traits for marine food web interactions to better understand the effects of climate change on the distribution of Albacore tuna in the Eastern Pacific. I earned my Ph.D (2020) working with Su Sponaugle at Oregon State University, studying the importance of planktonic prey availability and fine-scale distributions for larval tuna and reef fish success in the Florida Current. Prior to this I worked with Dr. Deborah Steinberg studying long-term changes in zooplankton communities in the scope of rapid climate change in the western Antarctic Peninsula during my B.Sc. (2010) and M.Sc. (2014) at The College of William and Mary/Virginia Institute of Marine Science.

Kyle Shanebeck

Co-supervised with the Lagrue lab

KyleI study the interactions between parasites and aquatic mammals. My project is investigating the sub-lethal effects of macro-parasites on river otter and mink in Alberta and British Columbia. Parasites are often considered unimportant in large mammal individual or population health; however, parasites can have complex effects on host energetics (systemic functioning, repair, growth, reproduction). My project asks: do parasitic helminths (worms) influence aquatic mammal individual fitness and population dynamics? Helminths also have complex relationships with pollutants (especially intestinal helminths); and heavy metals are an important threat for aquatic ecosystems in Canada. My project is also monitoring pollutants in both parasite and host tissues: are parasites related to increased or decreased accumulation of pollutants in their host? I was born and raised in southern California; was a research assistant with the Tinker Lab (UCSC) and volunteered for the Monterey Bay Aquarium’s Sea Otter Research and Conservation Program. I completed my MSc in Ecology at the Universität Bremen, Germany; where I studied the demographics and site selection of intestinal Acanthocephalans in Sea Otters and Seals through the Institute for Terrestrial and Aquatic Wildlife Research, University of Veterinary Medicine Hannover, Foundation. I am passionate about marine conservation, parasitology, and cross-discipline collaboration in research!

20220427_103219 (1)

I am a PhD candidate at the University of Alberta in the Biological Sciences department co-supervised by Mark Lewis & Stephanie Green. I am currently based at the University of Victoria as a visiting graduate student. I work on research questions to do with the population biology and fisheries management of marine invertebrates, with a specific focus on the enigmatic lives of spot prawns and their trap fishery on the coast of British Columbia. Prior to starting my PhD, I worked on several projects focused on wild Pacific salmon, ranging from field experiments investigating their behavioural ecology as juveniles to broad scale analyses informing population status assessments. Across projects and study species, I work to combine on-the-ground “boots-wet” biology with quantitative tools and existing long-term data sets. When I’m not coding, I like to cycle, spend time on the water, and dance my heart out to a good tune.



Julia Briand

headshotI am interested in the functional ecology of coral reef ecosystems under climate change and other anthropogenic stressors. My PhD research focuses on evaluating where and how restoration of reef function can succeed under the multi-scale impacts of stressors across heterogenous coastal habitats. My work aims to equip managers and practitioners with the information needed to design restoration projects that support reef functioning and resilience. Prior to beginning my PhD, I completed a MSc degree jointly at McGill University and the Smithsonian Tropical Research Institute (STRI) under the co-supervision of Dr. Jennifer Sunday and Dr. Hector Guzman. My Masters research focused on assessing spatio-temporal patterns in coral reef composition and function across an environmental gradient in the Caribbean. When I am not conducting research, I enjoy pursuing projects related to science education and outreach. I am currently a member of the International Coral Reef Society (ICRS) Student & Early Career Chapter.



Caitlin Hall

_DSC3006My main research interests lie in investigating the dynamics of functional ecology in coral reef systems and how broad-spectrum metrics may be used to enhance reef restoration planning and monitoring efforts. I am passionate about the use of environmental conservation as a tool to foster positive social change. As such, through my work I aim to focus on the development of accessible tools and practices which may be utilised in varied contexts to facilitate ecological recovery in local reef systems. Prior to starting my PhD, I completed an MSc degree at the University of Sussex. My research focused on investigating the functional ecology of a kelp forest ecosystem in a transient recovery phase following the cessation of long-term anthropogenic disturbance. When not conducting research, I enjoy exploring the great outdoors and spending as much time underwater as possible!



Fabian Kyne

Fk 3I am a PhD candidate at the University of the West Indies, Jamaica; co-supervised by Dr Stephanie Green. I am researching the ecology of the invasive lionfish and developing methods for impact assessment, mitigation and adaptive management for protected areas along the Belize Barrier Reef. I use a mixed methods approach, combining ecological monitoring and socio-economic data to assess how the lionfish invasion is impacting fisheries and coastal resources within Belize as well as developing recommendations for management. The outputs will be shared through a multi-stakeholder working group and national strategy which sets out a holistic framework for integrating ecological, economic, and social goals for managing invasive species in Belize. Prior to the PhD, I completed an MSc at the University of Southampton, UK and have worked across the Caribbean to disseminate knowledge and establish impactful conservation strategies and solutions that strengthen the resiliency of marine ecosystems and the people dependent on them. I am happiest being around, above or underwater and I am passionate about developing local conservation champions to impact change.

Cole Brookson 

IMG_5187My research focuses on using computational tools to investigate how ecological networks rewire in the wake of perturbations. I work mainly on food webs, and I am interested in how we can use species traits to better predict and understand how trophic structures change as a result of various types of anthropogenic disturbance, in both broad theoretical contexts as well as specific applied systems. Previous to my work at the University of Alberta, I completed my undergrad in Ecology and Evolutionary Biology at the University of Toronto, where I worked on modelling population responses to pollutants and pathogens in aquatic ecosystems. I am passionate about Open Science and promoting computational literacy and training in the biological sciences.

Alana Krug-MacLeod

Alana profileFor the moment I’m getting my feet wet by filling prey trait data gaps for California Current albacore tuna. I look forward to feeling the ocean spray next summer when I may examine stomach contents of tuna caught by fishers or prey communities in the water column where tuna feed. I completed an interdisciplinary undergraduate honours degree in Environmental Biology at the University of Saskatchewan (USask). A highlight during my undergrad was attending the Korean Arctic Academy and sharing research on the role of the Cumberland Sound indigenous community in protecting Cumberland Sound beluga. Another was volunteering on biodiversity projects at a pre-congress and sharing my Antarctic and ctic experiences with Students on Ice at the International Union for the Conservation of Nature (IUCN) Congress in Hawaii. My USask lab research included assessing persistent effects on shorebirds of in ovo exposure to contamination and temperature stress, using GIS to identify opportunities for grain farmers to increase ecosystem services, and processing fish bone samples from Viking middens to monitor climate changes.


Milène Weibe

Co-supervised with Dr. Kyle Artelle, Heiltsuk Integrated Resource Management Department 

Green WebsiteMy research focuses on the invasion ecology of European green crabs (Carcinus maenas). In particular, I am evaluating management strategies that aim to limit their negative effects on intertidal communities within the traditional territory of the Haíɫzaqv Nation on the central coast of British Columbia in collaboration with the Heiltsuk Integrated Resource Management Department. Previously I gained experience with invasive species with Parks Canada, working to stop the spread of zebra mussels (Dreissena polymorpha) in Manitoba. My honours thesis at the University of Manitoba focused on determining if proximate body condition could be used as a predictor for fecundity in sea lamprey (Petromyzon marinus) within the Great Lakes. I am passionate about conservation and wildlife management, making science accessible, the outdoors, and dogs.



Isla Turcke

IMG_9427I study how functional connectivity modeling can inform restoration initiatives on coral reefs in the Florida Keys. Currently, I am looking at the spatial distribution of blue, midnight, and rainbow parrotfish, and using this data to model how these species are moving across the seascape. Before joining the Green Lab I obtained my BSc (Honours) in Integrated Science from McMaster University, with a major in physics and a minor in mathematics. This program taught me the value of interdisciplinary collaboration and effective science communication. I am excited to be beginning my journey in this field, as I have been passionate about the preservation of wildlife and their habitats since I was very young. Outside of school I like to swim, sail, bike, ski, coach gymnastics, or curl up with a good book!

Courtney Stuart (MSc Winter 2022)

Courtney_GreenWebPhotoI am a marine spatial ecologist who studied connectivity across the mangrove-seagrass-reef continuum of the Florida Keys. The main goal of my MSc was to construct species- and stage-specific models of habitat suitability for reef fish with complex life histories, particularly those that involve ontogenetic habitat shifts. These regional scale models are the basis for connectivity analyses and are fundamental to the construction of ecologically-relevant management plans. Prior to joining the Green Lab, I obtained my BS in Marine Vertebrate Biology from the School of Marine and Atmospheric Sciences at Stony Brook University. My senior honors thesis examined the patterns, rates, and socio-ecological consequences of tooth replacement in fishes of the Peruvian Amazon. I am passionate about diversity in the scientific community, science communication and mentorship, and #WomenInGIS.



Victoria Van Mierlo (MSc Fall 2021)

IMG_4538 edit1I studied the interactions of invasive Northern Crayfish (Faxionis virilis) with native freshwater fish communities and effects on food web dynamics in Alberta. As a lover of nature and native Southern Ontarian, I am especially interested in the extensive negative impacts that invasive species have on native ecosystems. I received my BSc in Honors Biology at McMaster University, where my thesis work was focused on the efficacy of entomopathogenic fungi to weaken the immune system of the invasive marmorated stink bug (Halyomorpha halys). Additionally, I participated in coral reef species assemblage surveys after the introduction of invasive lionfish at the Cape Eleuthera Institute. Through my MSc work, I hope to provide information to managers that improves invasive species management at the watershed level. I am passionate about sustainability, interdisciplinary solutions, and inclusion in science and research!

Aneri profile picI studied the effect of restoration activities on community dynamics and ecosystem assemblage using coral reefs as a model ecosystem. My interest in applied science is to create tools for conservation practitioners, while working with diverse collaborators to create sustainable conservation and restoration solutions. Prior to the University of Alberta, I completed research internships at the Coral Health and Disease Lab at Mote Mote Marine Laboratories in Sarasota, FL, and at Cape Eleuthera Institute in the Bahamas. My undergraduate research at the Marine Macroecology and Biogeochemistry Lab at Mount Allison University focused on quantifying major macromolecular pools in a dominant Arctic phytoplankton strain. I am passionate about diversity and inclusion in science, science communication, and tiny but vital organisms (ie corals, algae, and lichen!)


Noelle Helder (MSc Spring 2021)

IMG_E3331I studied how species assemblages on restored coral reefs in the Florida Keys affect nutrient recycling. Stemming from a strong interest in natural resource management at all levels, I aim to use applied sciences to better understand changes in economically valuable ecosystems and develop tools to influence better management decisions. Prior to my MSc, I spent time working with the School for Field Studies in the Turks and Caicos Islands and at the Central Caribbean Marine Institute in the Cayman Islands, developing an interest in engaging stakeholders starting at the community level in resource management decisions. As an avid outdoor enthusiast and guide, I am also passionate about experience-based education, expedition-based research, and empowering underrepresented communities to engage in scientific endeavors. My research uses SCUBA surveys, photogrammetry, stable isotopes, and spatially explicit modelling to understand feedbacks between reef fish communities and their habitat on coral reefs in the Florida Keys National Marine Sanctuary. We work closely with local partners including NOAA and the Coral Restoration Foundation. Previously, I have worked throughout the Caribbean on projects relating to Marine Protected Areas, coral reef conservation, and science communication. I also co-lead the Education and Outreach Committee with the International Coral Reef Society Student Chapter.
