Jennifer Williams, Professor, Department of Geography & Biodiversity Research Centre

I am interested in the eco-evolutionary dynamics that shape population abundance in one location through time and that drive population distributions in space. I incorporate a demographic perspective in much of the research that I do to better understand the underlying drivers of patterns we observe using a variety of simulation and mathematical models. I continue to be fascinated by questions about invasive species, with a more recent focus on understanding variability in speed during range expansion. [Google Scholar profile]

Jenna Loesberg (Ph.D. student)

I'm interested in understanding the demographic processes underlying how populations respond to changes in climate. My PhD examines how climate drivers interact with life-history trade-offs, density, and invasive plants to influence native plant demography and population persistence. I look at these processes in native perennial and annual forbs within our lab's rainfall manipulation experiment on Vancouver Island. Read more about my research on my website.
Carla Urquhart (Ph.D. student)

My research focuses on how rapid evolutionary processes during range expansions shape, and are shaped by, ecological dynamics. Using both experimental expansions in the greenhouse and simulation models I am investigating the role of evolution in determining how well we can predict expansion speed, as well as the influence of mating systems, Allee effects, and interspecific competition on the eco-evolutionary dynamics of range expansion.
Robin Bradley (M.Sc. student)

I am investigating the long-term effects of drought on Garry oak savanna plant community composition and beta diversity. I am interested in how climate change impacts plant species dynamics and shifts in plant community structure.
Lucky Barahebuza (Ph.D. student) - co-supervised with Naomi Schwartz

My research focuses on the impact of anthropogenic activities (such as hunting, global warming) on the regeneration and spatial structure of tropical forest ecosystems and the implications for key ecosystem services. Before beginning doctoral studies, I earned a master’s degree in Ecology and Evolutionary Biology from the University of Connecticut, USA. As a fun fact, I enjoy the outdoors, mainly hiking, running, and socializing with family and friends.
Jian Zheng, UBC Work Learn International Award and undergraduate assistant

I assist with Arabidopsis experimental range expansions. I am also researching how plant traits influence range expansion speed under varying density conditions.
