Chris Rackauckas
Dr. Rackauckas is a Research Affiliate and Co-PI of the Julia Lab at the Massachusetts Institute of Technology, VP of Modeling and Simulation at JuliaHub and Creator / Lead Developer of JuliaSim. He's also the Director of Scientific Research at Pumas-AI and Creator / Lead Developer of Pumas, and Lead Developer of the SciML Open Source Software Organization.
Dr. Rackauckas's research and software is focused on Scientific Machine Learning (SciML): the integration of domain models with artificial intelligence techniques like machine learning. By utilizing the structured scientific (differential equation) models together with the unstructured data-driven models of machine learning, our simulators can be accelerated, our science can better approximate the true systems, all while enjoying the robustness and explainability of mechanistic dynamical models.

Whether through Cython, Rcpp, or other interfaces, many of the common packages in the Python and R ecosystems contain large amounts of C code for the package internals. The reason for this is performance: C is just a faster language than Python and R. However, Julia is also as fast as C while having higher level semantics similar to Python and R. Could one build Python and R packages using Julia? In this talk we will discuss how diffeqpy/diffeqr were built as packages to allow Python/R users to use Julia's DifferentialEquations.jl in a simple way. We will discuss topics from automating GPU compatibility, packaging precompiled binaries of Julia code, and automating interface wrappers which enable doing this efficiently. The audience will leave with a clear idea of how to use Julia as an alternative to C for package internals.
