About
I am a Forensic Scientist with the Mesa Forensic Services Crime Laboratory, specializing in serology and body fluid identification, with a B.S. in Forensic Science from Arizona State University's Barrett, The Honors College. My work focuses on the analysis of bodily fluids and evidence processing within an accredited crime laboratory.
I completed an eight-month internship with the Arizona Department of Public Safety Crime Lab and spent two years as an undergraduate researcher in ASU's Forensic Entomology/Genetics Research Lab, contributing to four projects, multiple presentations, and peer-reviewed publications. I am detail-oriented, methodical, and currently undergoing DNA training, with a strong commitment to accuracy, quality, and continuous professional development.
I welcome opportunities to collaborate within the forensic science community.
