About Me

I am a bacterial geneticist from Puerto Rico. I earned my bachelor's degree in Microbiology from the University of Puerto Rico, Humacao, where I participated in PR-LSAMP and MARC-U*STAR undergraduate research programs. I completed my PhD degree in Microbiology from the University of California, Davis, where I studied the origin of mutations under stressful conditions with John R. Roth, PhD as my doctoral advisor. Currently, I am a full-time Biological Sciences lecturer at Sacramento State. I also work with the CSU-LSAMP Statewide Alliance, the CSU-LSAMP at Sacramento State  and the RISE Programs preparing the next generation of scientists. 

I also work as an independent artist creating artwork to increase the visibility of women of color, who have historically been underrepresented in STEM.
