Rockstar🎓
Top SchoolAbel Siqueira is a Senior Research Software Engineer with 14 years of experience blending numerical optimization research and sustainable research-software engineering, currently based at the Netherlands eScience Center. He leads development of Tulipa, an open-source energy system optimisation model in Julia (JuMP), and has deep expertise in solver development through co-creating the JuliaSmoothOptimizers organization. His background as an assistant professor and PhD in Applied Mathematics informs rigorous practices—automated testing, linting, CI and documentation—across projects in Julia, Python, C++, and Typescript. Abel frequently bridges research and production: from CUDA C++ wrappers and cloud/Kubernetes simulations to web tools like cffinit and GitHub Actions for citation validation. He also runs a Portuguese-language YouTube channel discussing Julia and life in the Netherlands, reflecting his commitment to community education and international collaboration. Colleagues value him for turning advanced numerical methods into maintainable, reproducible software that researchers can reliably adopt.
