Bridging Applied and Theoretical Ecology

 

I am a Postdoctoral Fellow at the Universities of British Columbia and Montana working with Drs. Adam Ford and Mark Hebblewhite


I work at the interface of population ecology,  human-wildlife co-existence, and wildlife management. My work provides rigorous and insightful evidence that informs wildlife management, theoretical population ecology and maximizes conservation gains for wildlife, wild places, and local land stewards.


 

 

Ecological Gradients


Tracking ecological interactions across anthropogenic and productivity gradients to illuminate the complex dynamics of wildlife populations.


 

 

I take a population and behavioural ecology approach and ask questions such as:

Which bottom-up and top-down forces limit population density?

How do vital rates interact to produce observed population density?

How do we maximize conservation gains for wildlife populations?

What can be done to mitigate human-caused impacts on wildlife?

 

 


I use non-invasive DNA sampling to glean ecological insights that can scale from alleles to ecosystems. I track individuals with GPS collars to understand fine-scale connectivity and demography at a population-level.
