Interface capturing
One of the questions I keep returning to is how a moving interface should be represented when the system is complex, unsteady, and numerically unforgiving.
Research
Research interests and academic background.
My work is centered on simulation problems where interfaces, waves, and strong gradients are hard to treat well but worth getting right.
Current Topics
Three recurring directions.
The details move around, but these three topics keep showing up as the main thread.
Sharpness and stability at the same time
It is not enough for an interface to remain visible. The method also needs to behave well when the rest of the flow field becomes difficult.
Two-phase flow
I am especially interested in problems where the interface is doing real physical work instead of just acting like a boundary line to be tracked.
Interface behavior drives the whole system
When the phase interaction matters to the larger dynamics, the numerical method becomes part of the physics conversation.
Detonation modeling
Reactive compressible flow, shocks, and unstable structures are part of what makes this corner of simulation both demanding and interesting.
Strong gradients are the whole point
These are exactly the cases where both post-processing and numerical treatment need to stay honest.
Real Sources
A few real motion studies.
I keep a few real clips here because they fit this page better than another made-up animation.
Academic Path
Virginia Tech and Georgia Tech.
The academic path moves through both aerospace engineering and computational science, with Georgia Tech at the center of the graduate work.
