Paul Lang works in developing comprehensive models of biochemical reaction systems and supporting software tools. He obtained a BSc degree in Molecular Biology at the University of Graz (Austria) and an MSc degree in Molecular Health Sciences at ETH Zurich (Switzerland). He then switched from experimental to computational research. During his PhD at the University of Oxford (UK), Paul developed a rule-based cell cycle model that explains location and dynamics of 16 observables in RPE1 cells. As visiting scholar at the Icahn School of Medicine at Mount Sinai in New York (USA), he co-developed BpForms, a toolkit for concretely describing non- canonical polymers to enable the construction of whole-cell models. Paul also co-developed SBMLToolkit.jl, which imports SBML models into the SciML ecosystem. Currently, Paul works for JuliaHub on developing a parameter optimization tool for quantitative systems pharmacology. He also helps clients to translate their models to ModelingToolkit.jl ODESystems.
