 Education: Ph.D., University of California Berkeley, 2009
 **Work Experience:** Postdoctoral Associate, USDA-ARS, Invasive Species and Pollinator Health Research Unit, Albany, CA, 2014 to 2016.Project Coordinator, University of California, Berkeley, CA, 2011 to 2013. Graduate Student Researcher, University of California, Berkeley, CA, 2002 to 2008. Postdoctoral Researcher, University of California, Berkeley, CA, 2009 to 2014. Research Entomologist, USDA-ARS, Exotic and Invasive Weed Research Unit, Albany, CA, 2016 to present. Research Assistant II, University of California, Berkeley, CA, 2001 to 2002. Research Focus: The primary aim of my research is to improve control of invasive agricultural pests by using biological control agents. Specific objectives are to: Conduct surveys for natural enemies in the native and invasive ranges of agricultural pests.
Determine the safety of prospective biological control agents through host specificity testing.
Test the efficacy of biological control agents in controlling target pests.
Assess the impacts of natural enemies that are already present in invaded agricultural areas.
Examine the dispersal patterns of pests to identify sources for pest outbreaks.  **My current research projects include:** Biological control of bagrada bug and spotted wing drosophila
Movement of bagrada bug and spotted wing drosophila in the crop landscape
Efficacy of resident natural enemies of bagrada bug and spotted wing drosophila  ***Info about my research team:** Current lab members include: Dr. Keith Stokes, Alexandria Gutierrez, and Erica Pollard
