Biography

Lynn is an expert in data acquisition, firmware, and systems integration who has developed and deployed world-leading data collection capabilities for national security and fundamental particle physics. He has provided high-impact advanced data acquisition solutions for several complex projects, including the highest throughput High-purity Germanium (HPGe) detector reported in literature and a new, streamlined analysis capability at Pacific Northwest National Laboratory (PNNL). He provided technical contributions and leadership for multiple major inter-laboratory and international efforts, including the flagship experiment at an international high-energy particle collider. His expertise in high-rate data acquisition and signal processing is routinely sought to provide solutions to never-before-attempted data collection methods. He is an author on 116 publications, has served as a PNNL Team Leader and Cognizant Space Manager, and provides regular one-on-one mentorship to many staff and students. He has been called upon as a reviewer for the Department of Energy (DOE) Office of Science High Energy Physics program, was selected by the National Nuclear Security Administration to serve on a panel on priorities for a trusted microsystems capability, and has helped organize summer school programs in particle physics.
