Matthew Hielsberg is a Research Specialist V currently employed full-time by the Mathematics Department at Texas A&M University and is affiliated with the Institute for Scientific Computation (ISC) and the Institute of Data Science (TAMIDS).  Over the past 19 years, Mr. Hielsberg has worked to support many research efforts with graphics software, simulation, tool generation and support, cluster support and administration as well as student mentoring and training.  He has also collaborated with many researchers from several universities and businesses, and made contributions to many successful MURI’s, SBIR’s, STTR’s and other projects.  

From 2002 to 2010 Mr. Hielsberg worked for the Interdisciplinary Mathematics Institute at the University of South Carolina.  During his time at USC Mr. Hielsberg focused on creation of visualization tools, custom research applications and algorithm development.  He created tools for the real-time manipulation of molecules in Visual Molecular Dynamics (VMD) using USC’s stereographic CAVE and 6D mouse.  As part of the AVCAAF program he designed and developed several packages for feature tracking, structure from motion (SFM), and the real-time approximation of terrain from large point cloud data sets using mathematical learning theory.  Additionally, he created the USC Simulator, which enabled researchers to use common tools, including Matlab and the USC CAVE, to place simulated cameras and lidar-like sensors in 3D virtual environments for data generation and scenario development.  

Mr. Hielsberg was loaned to Texas A&M University in the fall of 2009 for the purpose of designing and developing both algorithms and software for hybrid implicit/explicit terrain learning from point clouds.  In 2010 Texas A&M University hired Mr. Hielsberg as an Associate Research Specialist.  Since that time he has worked with the Group for Analysis, Imaging and Numerics (GAIN) to develop software for visualizing and analyzing hyperspectral lidar, constrained optimization, parameter estimation of elliptic pde’s, data assimilation, compressive sensing, and deep learning.  He has also developed an introductory video series on the R programming language for the TAMIDS Biomedical Data Science Online Training Program, as well as a Python series directed towards the Math Graduate Program.  He has made contributions to the TAMU visualization center and to the PCL community, where he organized and maintained a repository of freely available research data and software.  In 2020 Mr. Hielsberg took over as administrator of the Whistler Computing Cluster for the Numerical Analysis and Scientific Computation group within the Mathematics Department.
