• About me

    I am a passionate scientist working in photonics

    I studied physics at the National Autonomous University of México (UNAM), where my interest for optics was seeded. This interest shortly became a passion that lead me to the National Institute of Astrophysics Optics and Electronics (INAOE) where I obtained a master in optics in 2010. During this period I worked for the first time with structured light, which became a passion. This conducted me to ICFO-The institute of photonics sciences where I obtained a PhD degree in photonics. In 2015 I became a research fellow at the structured light laboratory of the University of the Witwatersrand. From 2018 to 2020 I was a professor at the University of Science and Technology of Harbin, China. Since 2020 I am a principal researcher at the Center for Research in optics (CIO), Mexico. My main research interest involves the generation, characterization and applications of structured light beams. I am currently exploring the use of low-cost devices, such as Digital Micromirror Devices, to make these techniques available to any undergraduate laboratory. I have published over 50 research articles, including several review papers and a book. I am an editorial board member of JOPT and an active reviewer for, Opt. Lett., Opt. Express, Laser Photonics Rev., Sci. Rep., among others
