I use cameras to spy on wildlife. My research is focused on answering questions like:
Where are species present and why?
How many individuals are there in a population?
What strategies do species use to coexist together?
I firmly believe in building research capacity in other countries and hope to use camera traps and other noninvasive tools to further our knowledge of and ability to conserve threatened species across the world.

Naj: a sailor who is roped into a promise and must return her people's dead to their island home while avoiding certain death by vengeful gang leader.
Shi Veisya: the Goddess' right hand, who has awakened in blood and snow on the eve of apocalypse.
A flower dripping tar in the middle of a massacre. Metal ruins from a long-forgotten civilization. A land dying a slow death.
This is the world of Red Sun.
Red Sun is my current work-in-progress, an ecologically-inspired fantasy novel. Check out my patreon for updates!

How Do Carnivore Interactions & Distribution Influence Fawn Distribution & Survival?
For baby deer, the forest is a landscape varying in safety, changing depending on the habitat, time of day, and the predator that they are avoiding. Throw in more than one predator and you have a very complicated chessboard to navigate!
Using three years of camera trap data at three state forests in PA, I hope to figure out how fawns use habitat, space, and time to avoid being eaten by black bears, coyotes, and bobcats. Check out #whoseatingbambi for tweets!
How many fosa are there in Madagascar's largest protected area?
Madagascar's unique carnivore family (Eupleridae) is severely understudied. For many species, population estimates are lacking, which makes it very difficult to correctly determine how threatened they are.
Using data from fifteen surveys across seven sites, we found that there is likely about 1,000 adult fosa in the protected area (as little as 600 and as many as 1,800). This means that the Masoala-Makira protected area is home to a significant number of the fosa left in the world.
Can we use extra camera trap data to provide new information for little-studied species?
Camera traps are awesome because they take pictures of EVERYTHING that walks in front of the camera. We got thousands and thousands of pictures of birds, small mammals, and a (mainly) Madagascar-exclusive insectivore group called tenrecs.
Using this data we found that we were less likely to detect many of the bird species if we saw a lot of feral cats in the area, and that red forest rats (adorably rusty-colored pudgy rodents) were detected more often further from the forest edge.
Are lemur densities different between undisturbed and disturbed forests?
In addition to running fifteen camera trap surveys in Masoala-Makira, we ran lemur surveys on forest paths that we walked night and day. All told, we got over a thousand observations of lemurs, including critically endangered species like silky sifaka and indri, while walking over 1,000 kilometers!
We provided the very first statistically-rigorous population estimates of three species for the region, and found that you were less likely to observe lemurs in very disturbed forests compared to undisturbed forests.
