Optical Science and Engineering, Spring 2019. 

David Valdés earned his M.S. in Optical Science and Engineering at the University of New Mexico (UNM) in 2019 under the supervision of Dr. Jean-Claude Diels, author and Professor of Physics and Astronomy at UNM. David worked as a part-time student for the duration of his master’s program.

David currently serves as an Interim Associate Dean in the School of Adult and General Education at Central New Mexico Community College (CNM).

David taught math for two years at West Mesa High School before beginning work as a member of the full-time math faculty at CNM in the School of Adult and General Education. In addition to his faculty position, he also worked as a CNM Presidential Fellow, and Faculty Senate Chair.

After completing his master’s degree at UNM, David was offered an interim associate dean position to fill one of two positions that became vacated. In this role, he has helped see the college through the ups and downs of navigating COVID-19 while managing faculty schedules and serving on various college committees. David also directs the Adult Basic Education program which oversees state and federal grants to help students learn English and attain their high school equivalency. Complementing his work at CNM, David serves as a full board member of the Workforce Connection of Central New Mexico, which strives to address the workforce needs in the central region.
