Justin C. FengPh.D Physics, The University of Texas at Austin (To be conferred December 2017)


Howdy! I am a former UT graduate student, now a research affiliate in the physics department working with Prof. Richard Matzner in the relativity group. Here's my cv. Research InterestsMy research is a mixture of theoretical and numerical work in General Relativity. In particular, I work on topics involving variational principles in General Relativity (with a focus on boundary terms), the 3+1 formalism and the PostMinkowskian approximation. My dissertation concerns spatial boundary conditions in the path integral formulation of quantum General Relativity. PhysicsMy Notes:The Poor Man's Introduction to Tensors  These are my notes on tensorsThese are intended to serve as an introduction to tensor calculus (in Euclidean space) accessible to those with a basic knowledge of linear algebra and vector calculus.
