To harness the Proton-Proton collisions at the highest energy of unprecedented rate, innovative approaches must be explored and recent development in artificial intelligence (AI) offers such opportunities. In my talk, I will introduce essential elements in boosting the discovery potential with accelerated AI: science drivers at the LHC, interplay between Machine Learning (ML) and domain knowledge, as well as ML-specific compute systems. I will highlight a few studies in ML algorithms, in collaboration with experts in Purdue CS, that enable important science topics at the LHC. I will also discuss the challenges of realizing ML in scientific instruments and solutions explored in my previous work. At the end of my talk, I will introduce the multidisciplinary NSF A3D3 (accelerated AI algorithms for data driven discovery) HDR institution and how these explorations can benefit science domains broadly. Bio: She completed her PhD at Duke University in 2015, her thesis work is on establishing the first evidence of triboson processes with W boson produced associated with two photons using ATLAS data. As a postdoc at fermilab from 2015 to 2020, she performed searches for three heavy gauge bosons events that led to the first observation of the VVV process and evidences of WWW/WWZ with CMS 13 TeV proton collision data collected during LHC Run-2 operation. she also searched for SUSY particles such stop Pairs and electroweakinos using CMS early Run-2 data. She led the commissioning and testing of the CMS phase 1 forward pixel detector pre/post installation at fermilab and is continuing to contribute to the cms phase 2 outer tracker upgrade as an assistant professor at purdue University starting in 2020. Her recent work focuses on improving CMS physics sensitivities with machine learning and heterogeneous computing hardwares.
