Biography: "Yan Liu (academically, a.k.a. Yan Y. Liu) is Staff Research Scientist\
\ at the Computational Urban Sciences Group (CUSG) in the Computational Science\
\ and Engineering Division (CSED) at the Oak Ridge National Laboratory (ORNL).\
\ He joined ORNL in March 2019 to pursue research and development (R&D) interests\
\ in scalable and high-performance geocomputation. He obtained his PhD in Informatics\
\ from the University of Illinois at Urbana-Champaign, M.CS from the University\
\ of Iowa, and B.S. and M.E.from Wuhan University, China. He was Senior Research\
\ Programmer at the National Center for Supercomputing Applications at the University\
\ of Illinois Urbana-Champaign from 2014 to 2019. \n\nYan's primary interest is\
\ in the development of high-performance and scalable algorithms and software,\
\ with a particular interest in scalable geocomputation and high-performance heuristic\
\ algorithms. He has designed scalable approaches for large-scale geospatial optimization\
\ problems, harnessing massive supercomputing resources on cyberinfrastructure.\
\ He was a lead developer of GISolve middleware -- a leading GIS solution on cyberinfrastructure\
\ (July 2007 to September 2010) and the project manager of the NSF CyberGIS project\
\ (October 2010 to April 2012). He led the technical program at the CyberInfrastructure\
\ and Geospatial Information Lab (CIGI) from 2007 to 2014 and at the CyberGIS\
\ Center from 2014 to 2018, and led software architecting and development of CyberGIS\
\ core capabilities and funded projects. He was also a staff scientist in XSEDE\
\ (the successor of TeraGrid) to provide advanced cyberinfrastructure consulting\
\ for domain-specific scientific computing, performance profiling and optimization,\
\ and science gateways.\n\nWorking with hydrologists, he developed a scalable\
\ computational solution to continental flood inundation mapping (CFIM) in the\
\ NSF National Flood Interoperability Experiment project. This high-performance\
\ CFIM framework produces a high-resolution hydrologic terrain for the conterminous\
\ U.S. and was used in August 2017 for Hurricane Harvey relief and recovery in\
\ the State of Texas. He is lead developer of a high-performance spatial partitioning\
\ and districting software, which scales up to 131,072 processor cores on Blue\
\ Waters, the most powerful supercomputer in academic computing (as of May 2017),\
\ to provide a supercomputing solution to the study of large district modeling\
\ problems. He is co-PI for a high-performance computational sociology project\
\ funded by NSF from 2018 to 2021. His work in spatial optimization and statistical\
\ sampling and its application in district modeling received the HPC Innovation\
\ Excellence Award in 2019 by HPC User Forum."
