Current activities

I am currently a National Science Foundation Minority Postdoctoral Fellow at Stanford University in Deborah Gordon’s laboratory. I am generally interested in interactions among tropic levels within communities, and how communities and their interactions change over time.  I also really enjoy mixing field research with mathematical modeling to maximize understanding of interactions and changes in communities.

Since beginning my postdoc, I have been studying the interaction among invasive Argentine ants and invasive plants, and also how the Argentine ant invasion changes interactions among native ants. I am using null modeling techniques to examine how native species segregate or aggregate and how this changes with invasion and over time. My research in California takes place in the Midpeninsula Regional Open Space District and at Jasper Ridge Biological Preserve.

I also have a continuing research project on Robinson Crusoe Island, Chile, where I have been monitoring invaded plant communities for the last eight years.  There I ask how disturbance and exclusion of invasive rabbits differentially impacts plant species.  For this project: I used Markov models to examine transition probabilities under different treatment conditions and to predict results of management, I examined the importance of native range overlap with rabbits to invasion success, and finally how key underlying population dynamic parameters change among plant groups and with rabbit exclusion and disturbance.  I look forward to using this system in the future to examine long term recovery from disturbance and much more.  This project began as my dissertation at the University of Chicago, where I was advised by Timothy Wootton.
