Breaking New Ground in Augmented Reality: The Inspiring Journey of Alejandro Velez-Zea

In an enlightening conversation with Alejandro Velez-Zea, an innovative assistant professor at the University of Antioquia in Colombia, we delve into a remarkable career that intertwines optical technology and augmented reality. With a commendable foundation from his undergraduate studies at the very same university, Velez-Zea pursued advanced education at the National University of La Plata in Argentina, where he focused on optical encryption methods, digital holography, and holographic displays during his Ph.D.

Velez-Zea's groundbreaking work achieved significant recognition when his project on augmented-reality holographic displays clinched the prestigious 2023 Optica Foundation Challenge prize. In his own words, the award was instrumental to the project’s success, underscoring his drive and innovative spirit.

A Journey of Discovery in Optics

Reflecting on his career journey, Velez-Zea emphasizes the importance of exploring multiple facets of a discipline. Initially hesitant to commit to one specific area in optics during his undergraduate studies, he pursued an internship in optics and photonics, which provided vital exposure and experience in both experimental and computational aspects of his field. This blend of disciplines allowed him to develop a holistic understanding of optics, critical for his future projects.

During his Ph.D., Velez-Zea worked closely with Roberto Torroba, pioneering research in optical encryption methods that would elevate existing technologies in digital holography. His journey highlights how interdisciplinary approaches often lead to groundbreaking advancements.

A Passion for Problem-Solving and Mentorship

Velez-Zea describes his motivation as twofold: solving theoretical and experimental challenges, and mentoring the next generation of researchers. The satisfaction gained from witnessing his first student graduate and publish research serves as a testament to his impact as an educator and mentor. His commitment to nurturing talent shows that the influence of a professor extends beyond lectures and classrooms.

Innovating with Digital Micromirror Devices

His winning project, titled “Multilayer Holographic Augmented Reality with Digital Micromirror Devices: Content Pipeline and System Implementation,” aims to revolutionize holographic displays through affordable and fast-operating digital micromirror devices (DMDs). Unlike traditional phase-only modulators which are costly, DMDs present a promising alternative. While the binary amplitude modulation approach of DMDs poses challenges for hologram generation, Velez-Zea’s findings suggest that adapting recent advancements in holography to DMD characteristics could democratize access to holographic technology.

His experience with the Optica Foundation Challenge has enhanced his research capabilities, allowing him to acquire essential experimental equipment and provide further educational opportunities for dedicated students.

A Note on Balance and Mentorship

As he reflects on his past, Velez-Zea emphasizes the significance of personal well-being. In the quest for research excellence, balancing health, relationships, and life outside academia can often be overlooked, a lesson he advocates to students and early-career researchers alike.

When discussing effective mentorship, he underscores honesty and empathy as vital. A transparent portrayal of the research landscape fosters realistic expectations, while empathy assures mentees that their challenges are acknowledged and understood.

Advice for Aspiring Researchers

Aiming to empower students and emerging scholars, Velez-Zea advises prioritizing self-care, understanding the broader context of their research, and adapting expectations in the face of inevitable setbacks. Success in research is multifaceted, influenced by numerous external factors, making resilience and adaptability crucial abilities.

Conclusion: A Vision for the Future

Alejandro Velez-Zea’s journey is not only one of personal achievement but also of a commitment to advancing optical technologies and mentoring future innovators. As augmented reality continues to gain traction, his pioneering work stands to reshape our interactions with digital content and inspire the next generation of physicists to push the boundaries of what’s possible.
