Speaker Hanan Samet

Biography. Hanan Samet received a B.S. degree in engineering from UCLA, an M.S. degree in operations research and M.S. and Ph.D. degrees in computer science from Stanford University. At Stanford, he was in the Stanford Artificial Intelligence Lab where he was one of the developers of the SAIL programming language compiler. His doctoral dissertation dealt with proving the correctness of translations of LISP programs and was the first work in translation validation and proof-carrying code.

In 1975 he joined the Computer Science Department at the University of Maryland, College Park, where he is a Distinguished University Professor.  He is a member of the Computer Vision Laboratory and leadsa number of research projects on the use of hierarchical data structures.  He has over 375 publications on data structures, computer graphics, computer vision, geographic information systems (GIS), spatial databases, robotics, and search.  His research group has developed numerous systems including the SAND Browser which enables browsing through a spatial database using a graphical user interface, the VASCO spatial indexing applet, the STEWARD system for identifying the geographic focus of documents thereby facilitating the performance of spatio-textual search to enable searches that rank the results by spatial proximity rather than by exact match, the NewsStand and the CACM October 2014 cover issue with an accompanying video, and the TwitterStand system that apply these ideas to a database of news articles and Tweets, respectively, that enable them to be accessed using a map query interface.
