I have just started a postdoctoral position with Andy Russell at the University of Exeter-Cornwall where I will be
studying maternal effects in the chestnut-crowned babbler

and variability among individuals.

As a PhD student working with Lynn Martin in the department of Integrative Biology
at the University of South Florida, my research focused on how behavior (e.g.
exploration, response to novelty, and innovation) and stress physiology (glucocorticoid
release in response to stressors) changed throughout a natural range expansion.

To this end, I studied one of the world's most cosmopolitan species, the house sparrow
Kenya Map(Passer domesticus), in Kenya. House sparrows were introduced to Kenya in the
1950s, but are still undergoing range expansion; this creates an invasion gradient varying
in age from old populations (at the site of initial introduction) to new populations (at the
edge of the expansion). In this system, I  addressed behavioral and physiological variation exploration tent
among populations of Kenyan house sparrows. Interestingly, both behavioral and
physiological patterns exist among populations that vary with time since colonization. With
colleagues at USF and at Armstrong Atlantic University, I have also addressed genetic
and epigenetic patterns  throughout the range expansion in Kenya.
