Bio

Born and raised in Las Cruces, NM.

During my undergraduate studies, I was a member of the NMSU Flying Aggies Student Research Team. As a team member, I participated in NASA’s Reduced Gravity Student Flight Program , a national competition for flight slots. All three of my team’s projects were accepted and two were tested aboard NASA’s KC-135 at Johnson Space Center.

I also participated in the New Mexico Alliance for Minority Participation (AMP) Student Research Program, and obtained a New Mexico Space Grant Fellowship . As a member of the Summer Undergraduate Research Fellowship at Caltech , I completed a single internship at the NASA Jet Propulsion Laboratory followed by a second internship at Honeywell International .

Received the B.S. Electrical Engineering in 2007, and M.S. Electrical Engineering in 2010 from the Klipsch School of Electrical and Computer Engineering , New Mexico State University, Las Cruces, NM. Durring my graduate studies at NMSU, I worked full-time for a defense contractor at White Sands Missile Range .

In 2012, I began working on the Ph.D. degree in electrical engineering in the Ira A. Fulton Schools of Engineering , Arizona State University, Tempe, AZ. In 2014, I obtained a fellowship from the Acoustical Society of America . In May 2016, I completed an intership at Cirrus Logic and recieved the Ph.D. degree in electrical engineering from ASU. Fall 2016, I returned to the Klipsch School of Electrical and Computer Engineering at New Mexico State University as an instructor/faculty. My research interests include signal processing, specifically audio and speech processing, time-frequency analysis, machine learning, and robotics. My personal interests include being outdoors, gardening, swimming, playing the flute, and video games.
