Samuel Fogarty enhanced data processing pipelines for the DUNE project by focusing on performance optimization and data compatibility. In the DUNE/duneopdet repository, he accelerated waveform processing by replacing Signal() with SignalROI() in the Op Hit Finder, reducing data access latency and increasing throughput. For DUNE/waffles, he extended the HDF5 reader to support multiple detector types by introducing a detector parameter and updating mapping logic, improving interoperability across configurations. His work leveraged C++ and Python, applying skills in data engineering, configuration management, and signal processing. These targeted improvements enabled faster analysis cycles and broader support for diverse detector setups.
