Xifeng Gao

Assistant Professor @ Florida State University | gao@cs.fsu.edu | CV

I have wide research interests in fields related to Geometry, such as Computer Graphics, Visualization, Multimedia Processing, Medical Imaging, Information Forensics, and Digital Fabrication.

My current focus is to robustly discretize arbitrary shapes in various physical domains (2D planar, 3D surface, 3D volume, and 2D/3D+time), namely, Robust Meshing, providing high-quality meshes for applications in Finite Element Analysis (FEA), Isogeometric Analysis (IGA), and more broadly, Computer-aided Engineering (CAE) analysis.

Decoupling Simulation Accuracy from Mesh Quality! Tokyo, Japan! SIGGRAPH ASIA 2018! Welcome to the technical talk on Dec 5 afternoon!

Sep. 13, 2018

[Trip Canceled Due to Hurricane.] Oct. 10 to Oct. 12, I will attend the IGA 2018 conference: Integrating Design and Analysis, to be held in University of Texas at Austin. Welcome to the showcase of my project: PolyFEM, which does finite element simulation on a general mesh (2D/3D, triangle/quad/hybrid) and utilizes as much as possible of the regularity of the mesh!

Aug. 12, 2018

From Aug. 12 to Aug. 16, I will be in Vancouver, Canada, attending SIGGRAPH, the premier conference in computer graphics. Welcome to the technical talks of the projects I involved: Aug 14 in the morning Mesh cleaning Up Session and Aug 15 in the afternoon Textiles Session!

June 13, 2018

From July 3rd to July 5th, I will attend the Summer School held in the University of Science and Technology of China, and give a talk on robust meshing! On July 6th, I will give a talk on stitch meshing in a workshop held by GDC at the same place! Let's meet and chat. :-)

April 12, 2018

I am invited to serve on the International Program Committee of Pacific Graphics 2018. :-)

April 05, 2018

I will join the Computer Science Department of Florida State University as a tenure-track assistant professor starting from August 06, 2018!
