Summary
👤
Senior🎓
Top SchoolJustin Gullingsrud is a computational physicist and senior fellow specializing in building high-performance software for structural biology, with over a decade of experience developing MPI-parallel codes, C++ plugin architectures, and client-server visualization for terabyte-scale datasets. He combines deep molecular dynamics expertise with practical systems skills—C++, Python, Unix, OpenGL, MPI and pthreads—to deliver tools that bridge simulation, analysis, and interactive visualization. His long tenure at D. E. Shaw Research and current role at Treeline Biosciences reflect a track record of production-grade scientific software that supports large-scale simulation and real-time rendering. Justin’s background in physics (PhD, UIUC) and early academic work on protein kinase dynamics give him both theoretical grounding and domain intuition that inform robust engineering decisions. Notably, he pairs low-level performance tuning with user-facing visualization design, making complex datasets both tractable and explorable for scientists.
