Notable Alumni 

Dr. David Collao, SimCenter Alumni

Dr. David Collao

Ph.D. graduate in Computational Engineering in 2017

Dr. David Collao graduated from UTC with an MS (2011) and PhD (2017) in Computational Engineering. At UTC, the focus of Dr. Collao's PhD research was studying, via computational fluid dynamics simulations, how the operating stability of axial transonic compression systems was affected using a passive stability-enhancing method.

Today Dr. Collao is  a software and algorithms engineer at Branch Technology developing software tools and using them to create 3D grids that are “printed” by robots via extrusion. He says the most valuable skills that he learned working toward his PhD while at the SimCenter: mesh generation, computational geometry, and software development for scientific computing.

Dr. Collao's Advice for Current Students:

"Be willing to submit to the guidance of your professors. I found they’re willing to share their knowledge. Also, enjoy your friends in grad school. The friendships I’ve made in grad school have been tightest and most lasting even though these friends are thousands of miles away. And have fun!"


Dr. Philip Facker, SimCenter Alumni, 0217

Dr. Philip Fackler

Graduated in 2017 with a Ph.D. in Computational Engineering

Dr. Philip Fackler graduated from UTC with an MS (2013) and PhD (2017) in Computational Engineering.  His research focus was mesh generation—more specifically, populating and smoothing point distributions to match an arbitrary spacing field (which actually doesn’t involve a mesh). He says he's most proud of  the dynamic population control -- The algorithm could add and remove points as necessary to appropriately cluster points throughout the domain. From a single seed point, it could recursively spawn new points until the whole domain was filled in such a way that matched the spacing field pretty well and didn’t require much smoothing.

Dr. Fackler is a Research Software Engineer at the Oak Ridge National Laboratory. The SimCenter provided education in computational simulation, mesh generation, parallelism with MPI and OpenMP, and numerical analysis. He says all of these things led directly to his position at ORNL.

Dr. Philip Fackler's Advice for Current Students:

"Aim to write “good” code. There’s a lot on the internet about that topic, but basically you’re codifying knowledge, and you want that to be understandable to other people."
