Reserach Interests:

As Laboratory Manager and Safety Officer my duties entail maintaining a safe, clean and functional working environment for all of the post doctorate and graduate students that work in the group. My other responsibilities in the laboratory involve the handling and production of proteins specific to the group’s research focus.  Currently I am involved in 2 efforts:  the production of high quality NMR samples of kappa opioid receptor for functional and dynamic studies; and the production and study of mechanisms of RNA-binding motifs.       

 Curriculum Vitae:

2010 - Present:  Research Assistant III (The Scripps Research Institute, La Jolla, CA).
2005 - 2010:  Research Assistant I (The Scripps Research Institute, La Jolla, CA).
2003 - 2005:  Research Technician (The Scripps Research Institute, La Jolla, CA).
2002 - 2003:  Student Lab Associate (Salk Institute for Biological Studies, La Jolla, CA).
2003: Bachelor of Science w/ emphasis in cellular and molecular biology (San Diego State University, San Diego, CA).
