Teaching Philosophy: 

Science is about understanding the natural processes of the world around us so we can maintain ecosystems and communities.

Research Interests:

I am interested in applying novel techniques to facilitate conservation of native species. I am also interested in population management and finding new ways to control invasive species.

See the undergraduate research opportunities page for more.

“For in the end, we will conserve only what we love; we will love only what we understand and we will understand only what we are taught.”
