David Sperka

David Sperka is an Assistant Professor at Boston University, specializing in experimental particle physics. His primary affiliation is with the Department of Physics, where he leads efforts in developing high-speed reconstruction algorithms and CMS trigger systems. He is a key member of the CMS Collaboration at CERN and collaborates with the SpinQuest/DarkQuest experiment at Fermilab. His research focuses on addressing fundamental gaps in the Standard Model, particularly dark matter and the strong CP problem, through searches for axion-like particles and dark photons. He coordinates US CMS Software and Computing R&D for the High Luminosity LHC (HL-LHC), emphasizing GPU acceleration and data acquisition optimization.

David’s work involves advancing experimental infrastructure, including the Level-1 Global Trigger Menu design and the Data Scouting framework, which achieved the world’s most sensitive dark photon search at the GeV scale. He also adapts CMS vertex reconstruction algorithms for GPUs to tackle challenges from increased pileup at the HL-LHC, reducing processing time by an order of magnitude. His contributions include leading Higgs boson studies at CMS, such as the first observations of ttH production and H→bb decay, and producing precise Higgs mass measurements. Despite no listed educational background in the text, his roles reflect advanced expertise in particle physics and computing.

His research interests span dark sector physics, Higgs boson properties, and computational methods for collider experiments. While no specific scientific awards are mentioned, his publications and leadership roles highlight significant contributions to the field. Advising and grants details are not provided, but his active involvement in CMS and Fermilab experiments indicates collaborative research efforts. Key teams include the CMS Data Scouting Group, CMS Exotic Higgs Physics Group, and the HL-LHC Software R&D Coordination team.
