I am a theoretical astrophysicist at the Institute of Theoretical Physics, Jagiellonian University in Kraków, Poland. My research spans pre-supernova neutrino signatures from giant detectors (an early paper showed that roughly a week's warning before core collapse is feasible), 3D core-collapse supernova simulations, dark matter accretion onto black holes, rotating stars and accretion disks, and the interior structure of exoplanets and planetoids. I have also co-authored work on special functions and numerical integration.

I have used Mathematica in research and teaching at UJ for many years, and I am a contributor to the CCGRG package for symbolic tensor analysis in general relativity (Wolfram Library Archive #8848). Two decades of symbolic-regression experiments in the Wolfram Language, combined with earlier work on a single-element spherical tiling - a patented igloo-construction brick, described in Cambridge's Eureka journal - led me to the EML operator: a single binary function eml = Function[{x,y}, Exp[x] - Log[y]] that, together with the constant 1, generates standard scientific calculator operations. Mathematica served as the primary symbolic-verification environment, with independent numerical IEEE 754 confirmation in C, NumPy, PyTorch, and mpmath.
