I am a researcher at Siemens Corporate Technology focusing on medical image analysis and vision technologies. I earned a Ph.D. in Language and Information Technologies from the School of Computer Science at the Carnegie Mellon University (2009) where I worked with Jie Yang. Prior to joining Siemens in 2010, I briefly worked with Howard Wactlar and Alex Hauptmann as a postdoc in the Computer Science Department at CMU. I have also received a M.Sc. in Computer Science from the National University of Singapore (2003) and a B.Eng. in Computer Science & Technology from the Tsinghua University (2001).
My research at CMU focused on development of multimedia technologies for landmark-based vehicle navigation such as landmark labeling, detection, recognition and human vehicle interface. I also worked on some problems in machine learning.
