Summary
👤
Senior🎓
Top SchoolThomas Christensen is an Associate Professor and Villum Young Investigator at DTU with nine years of research and software development experience spanning photonics, topological physics, and graphene plasmonics. He held postdoctoral and research scientist roles at MIT and has a strong academic foundation from DTU and time at UC Berkeley, with publications tracked on Google Scholar. Equally at home in theory and code, he contributes to high-profile open-source projects such as the Julia language and StaticArrays.jl, improving numerical robustness and performance in core linear algebra routines. His work blends deep physics insight with low-level numerical optimization—evidenced by contributions that fixed type-stability issues and sped up inv() and array operations in Julia’s standard library. Based in Boston, he combines teaching experience from early DTU roles with an ability to translate advanced photonics concepts into reliable computational tools. Colleagues would note his uncommon mix of academic rigor and hands-on backend engineering in scientific software.
