Current Research Focus:
· Detecting genetic evidence of domestication in phytophagous insects and host plant switching in their wild relatives.
· Using molecular markers to delineate the geographic origins of the cochineal insect (Dactylopius coccus) that has been used as a brilliant red dye since pre-Columbian times in Peru and Mexico.

· 2009 to present: Molecular systematics and population genetics techniques training in the labs of Dr. Bernie May.
Currently training in molecular techniques for reconstruction of phylogenies and population networks, primer design, sequencing on an ABI-3730xl platform, and PCR optimization.
· 2010 Molecular Cloning in the lab Dr. Steve Nadler Lab: Learned how to clone PCR amplified fragments. Cloned fragments were then used to design species specific primers for phylogenetic analyses.
· 2008: Survey of Argentinean Cochineal Insects: Working with Dra. Lucia Claps of La Universidad de Tucuman. This survey was conducted in order to collect Dactylopius specimens from the different species and tribes of Opuntioid cacti found only in Argentinian deserts.
· 2007: Cochineal insect production and survey of the cochineal insects of Southern México.
Established collaborative projects with the Universidad de Guadalajara faculty Dr. Liberator Portillo and Ana Lilia Vigueras. Also traveled to southern Mexico to collect Oaxacan cochineal insects. This project was undertaken in order to try and discover where the cochineal insect originated by using genetic markers to compare genetic diversity of Mexican cochineal insects to Peruvian cochineal insects.
· 2006-2007: Assesment of fish chemicals effects on Mosquito Oviposition.
As part of my Masters research investigated if three different mosquito species are deterred from oviposition sites that have water containing fish chemicals.
· 2005-2007: Comparative Efficacy of Mosquito Control and Mosquito Oviposition Deterrence by Fish.
This work was part of my Masters research, and was focused on assessing if an alternative to mosquitofish (Gambusia affinis) could be used in managed wetlands in Southern California. Assessed both of these treatments for affects on non-target aquatic organisms.
· 2005: Scarabaeid Survey of the Algodones Dunes in Southern California.
Undertook this study in order to assess the impact of Off Road Vehicle (ORV) use on endemic spring flying scarab beetles at the Algodones Dunes.
· 2005-2006: Biogeography of Dune Endemic Insects of Southern California.
As part of a California Desert Research Grant collected a variety of dune endemic insects from sand dunes in Southern California. These specimens would later be used in phylogenetic analyses in order to better understand the evolution and species delimitation of dune endemic insects.
· 2005: Pollination and Dispersal of Neotropical Vanilla.
