Summary
👤
SeniorLukas Koch is a senior postdoc and experimental particle physicist with a PhD and 11 years of experience turning terabyte-scale detector data into robust statistical measurements and machine-learning driven insights. He specializes in neutrino physics—cross-section measurements, detector development and operation—and is skilled in unfolding/forward-folding techniques and advanced inference methods. A hands-on scientific programmer and Python aficionado, he has made precision-focused contributions to widely used GEANT4 tooling (WCSim), improving time accuracy and numerical stability for supernova simulations. Based in Mainz, Germany, Lukas blends deep domain knowledge with practical software engineering to bridge simulation, data processing, and analysis pipelines for large-scale experiments.

Contributions summary:Lukas made several contributions focused on improving the accuracy of time calculations and data handling within the WCSim simulation. This includes adjusting time units in nuisance files, expanding the storage capacity for event times in the SN simulation, and fixing overflow errors in the digitizer. Furthermore, the user made significant changes to the PMT object, replacing single-precision floats with doubles to maintain precision in supernova simulations. These changes likely involved modifications to core simulation components.
