Moving interfaces and sharp flow structures.
I keep coming back to cases where the physics is hard and the numerical treatment matters just as much.

- Georgia Tech Aerospace Engineering Ph.D. student since 2022.
- Interested in sharp interfaces, hard flow structures, and clean numerical treatment.
- Keeping one place for research, notes, images, and a few things outside the solver.
Now
Atlanta, Georgia
Most of my time goes to simulation, reading, and figuring out how difficult flow features should be represented numerically.
Current stack
Interface tracking, multiphase flow, compressible flow, and post-processing that feels closer to a lab screen than a brochure.
CFD, reactive flow, and multiphase simulation.
The common thread is high-gradient flow problems that need both stability and resolution.
Research first, but not research only.
I also keep notes, photos, and a few non-work pages here.
Motion References
A few clips I like having on the front page.
These are public-source clips: launch footage, a vortex street, and a particle-flow visualization.
Selected Directions
What I am spending the most time on.
These are the three themes that show up most often across my current work and reading.
Interface capturing
How to move a sharp interface without letting the numerics wash it away or destabilize the whole problem.
Open topicTwo-phase flow
Problems where the interface is not just present, but actively shapes the behavior of the full system.
Open topicDetonation modeling
Reactive compressible flow with strong gradients, wave interaction, and a lot of numerical pressure.

Path
Virginia Tech to Georgia Tech.
My academic path has moved across aerospace engineering and computational science, with Georgia Tech as the center of the graduate work.
Virginia Tech
Undergraduate aerospace engineering study before transferring to Georgia Tech.
Georgia Tech B.S.
Finished undergraduate work in aerospace engineering and stayed on for graduate study.
M.S. in Aerospace Engineering
The graduate phase narrowed further toward simulation and numerically difficult flow problems.
Ph.D. and CSE coursework
Continuing doctoral work in AE, with computational science and engineering studies alongside it.
Elsewhere On The Site
Notes, photos, and a lighter corner.
Besides research, I also keep notes, photos, and a few lighter pages here.
Notes and downloads
Study material, the notes bundle, and topics I plan to organize more carefully over time.
Open notesCampus and city frames
Photographs from Georgia Tech and Atlanta, arranged more like a visual page than a file dump.
Open galleryResearch-adjacent references
Launch footage, ParaView, and a few off-hours references that still feel close to the same world.
