Richard Samuelson is a doctoral student researching category theory, convex analysis, and high-performance computing. He has made significant contributions to the CliqueTrees.jl package, implementing the ChordalLDLt multifrontal factorisation that underpins sparse symmetric positive-definite linear solves. These improvements accelerate nullspace and global-section computations in the CellularSheaves.jl library and enable more efficient compositional methods across the lab’s projects.
