Lu Lu

    Lu Lu is an assistant professor at UW–Madison in the Department of Physics. Her ultimate goals are to discover the origins of the highest energy particles and to understand their acceleration mechanisms. She did her Ph.D., on searching for EeV photons, at the University of Leeds and Universität Wuppertal. She then moved to Chiba, Japan, and performed searches for PeV neutrinos using IceCube data, leading to the detection of the first Glashow resonance neutrino candidate. She is a member of the IceCube Real-time Oversight Committee and focuses on the extreme-high-energy (EHE) alert channel. She also contributed to R&D of a new sensor designed for the IceCube Upgrade and will continue efforts for the high-energy extension of IceCube-Gen2. As a hobby project, she co-developed an augmented reality app, ICEcuBEAR, to visualize IceCube real-time alerts on mobile phones.
