His research interests include pattern matching algorithms, automata theory, and information retrieval. GPU (Graphical Processing Unit): A GPU has many cores, and plays an important role in developing efficient algorithms.Study on Secure and Efficient SearchesSearchable encryption system: A user sends an encrypted query to a server. The server searches for documents using the encrypted query.Studentsgetmainlyjobsrelatedtotheinformationtechnology.After GraduationIn the FutureElectrical& Computer EngineeringNon-volatile Memory Based on Spin of ElectronOurresearchisfocusedondevelopingultra-fast,high-density,non-volatile,low-power-consumingmemoryandlogicdevicesbasedondirectmanipulationofelectronchargeandspin.Weareparticularlyinterestedincontrollingthespinseitherpointedupordownbydirectlyapplyingelectricalcurrentorvoltage.Ourlaboratoryhasspecializedfacilitiesforfilmdeposition.Lithographyandothernano-sizefabricationfacilitiesinourlaboratoryhavetheabilitytofabricateelementsassmallasone-thousandththewidthofahumanhair.Wealsohavethefacilitiestocharacterizetheelectricalandmagneticpropertiesofthoseelements.Memoryandlogicalelementsarefundamentaldevicesforprocessinginformation.Currentmemoriesandlogicelementsarebasedonelectricalcharge.Withtheincreaseofcapacityanddensityofthedevices,leakagebecameanissue.Spintronicsexploitsboththeintrinsicspinandassociatedmagneticmomentofanelectron,andhasapotentialforthedevelopmentofmemoryandlogicaldevicesbeyondthecurrentCOMStechnologies.Around50%ofourundergraduatestudentsmovedontograduateschools.Someareworkingincompaniesthatdealwithelectronicsystemordevices,andsomeareworkingasgovernmentemployees,et.al.Itisourgoaltofostercreativeandexcellentstudentswithglobalminds.XiaoxiLiuProfessorProfile：2013~ Prof., ShinshuUniv.2003~2012, Asso.
