Jilei Tian

Research Leader in Intelligent Mobile Platform

Background

I joined Nokia Research Center as senior researcher, then as principal scientist and research leader, primarily in the area of spoken language processing and voice UI, and recently on context data intelligence and economics. I have been involved in developing multilingual language- and speaker-independent name dialling, SMS dictation, high quality text-to-speech synthesis, voice conversion. I am now leading a team working on rich context modeling to offer personalized and intelligent applications and services for mobile users by leveraging context sensing and advanced user profiling. I also manage European project (FP7) on personalized speech-to-speech translation in Nokia as well as the collaboratiive projects with the universities.

Prior to joining Nokia Research Center, I was assistant lecturer and lecturer in Institute of Information Science in Beijing Jiaotong University during 1988-1993. From 1993 to 1994, I worked at Beijing office of Mainlife Co. (HongKong) and YAMATO Scientific Co. Ltd. (Japan, adjunct), responsible for developing Chinese market of scientific instruments.

I received my BS and MS degrees in Biomedical Engineering from Xi'an Jiaotong University, China and PhD degree majored in Bioinformatics from University of Kuopio, Finland.
