Research Interests

Dr. Xin Chen is currently a Senior Engineering Manager and Research Scientist in the Highly Automated Driving organization at HERE whose team is completing pioneering work to achieve the automation of next generation map creation using computer vision and machine learning technologies. He worked in the Research organization from 2006-2012, where he prototyped sign recognition, traffic signal detection, road detection from satellite imagery and other automatic feature extraction approaches using imagery and LIDAR.  He worked in the Core Platform organization from 2012-2015, where he prototyped automatic road feature extraction from LIDAR and imagery, and map learning from vehicle sensor probe data. Xin has ten U.S. Patents and over 50 filed and pending patent applications in LIDAR and image analysis for mapping and he has served on an NSF (National Science Foundation) panel to evaluate and award funding to multi-million dollar projects advancing research in these areas. Xin is also the University Cooperation Ambassador for the Patenting organization at Nokia. Xin has been awarded 2010 and 2011 IMPACT awards to recognize “employees making outstanding contributions”, an award recognizing “Significant Intellectual Property Contributors” at Nokia for 2011-2012, 2013 and 2014 company-wide Hack Week top awards, and 2015 Berkeley Office Hackathon top award.

On the academic front, Xin has managed computer vision research collaborations with academic teams including Carnegie Mellon U., Columbia U. and the U. of Notre Dame. Xin is an adjunct professor and PhD advisor at Northwestern U. and Illinois Institute of Technology teaching  “Geospatial Vision and Visualization” and “Biometrics” courses at both universities. Xin has served as a program chair and on the committee for several premium international conferences and workshops in computer vision and computational transportation. Xin obtained his Ph.D. in Computer Science and Engineering from the U. of Notre Dame.
