Portrait of Daniel Velazco-Garcia

Senior Software Engineer at Tietronix Software, Inc.
Ph.D. in Computer Science, University of Houston

I build digital twins, physics-based simulations, and extended reality experiences — applied research and engineering for problems with real-world stakes.

About Me

Hi — I'm Daniel. I'm a Senior Software Engineer at Tietronix Software , where I lead research and development across digital twins, physics-based simulation, and extended reality. I earned my Ph.D. in Computer Science from the University of Houston in 2022, with a dissertation on augmented reality for medical imaging visualization and human-computer interaction with medical data.

My work today builds on the same question that drove my doctoral research, with a wider lens: how do we design interactive 3D systems that help people understand, predict, and influence the physical world? Whether the domain is healthcare, aerospace, energy, or infrastructure, I want the software I build to leave society a little better than it found it.

Currently

NASA STTR · Principal Investigator

Leading a NASA STTR on shared extended reality for extravehicular activity (EVA) surface operations. Phase II recently wrapped; we are awaiting decision on a Phase II-E extension.

Digital twins

Building digital twins across NASA mission contexts, concentrated solar power (CSP) plants, and data centers — primarily in NVIDIA Omniverse.

Physics-informed neural networks

Recently built a PINN for a thermal receiver tube and expect to do a lot more PINN work in the coming months as the team leans into physics-aware ML.

Educational programming videos

Putting together a free programming video series aimed at students with no prior background — see the Media page for updates.

How I Got Here

My obsession with computing started in my teens, with my first computer — which I broke more than once trying to figure out how it worked. Pairing that curiosity with a strong math background turned into a degree, then a Ph.D., and now a career.

The thread running through all of it is the same: I want to build solutions that help society and humanity, while doing something I enjoy. Digital twins, in particular, sit right at the intersection of things I care about — math, simulation, software craftsmanship, and real-world impact.
