Professor Hao Tang has taught courses in Computer Information Systems at BMCC since 2012. The U.S. Department of Homeland Security has funded one of his most recent research projects, focused on developing computer software that will measure crowd distribution and density. In this project, Professor Tang worked closely with researchers at the Command, Control and Interoperability Center for Advanced Data Analysis (CCICADA) at Rutgers University, The State University of New Jersey.
Professor Tang has encouraged BMCC students to take part in his research projects and has guided students in presenting their research findings related to software development in poster sessions through the CUNY Research Scholars Program (CRSP).
His interests in 3D computer modeling, visualization of large-scale scenes, mobile vision and navigation have led him to participate in research projects like Smart Sampling, a project that used stereovision to help the visually impaired. A similar project led by Professor Tang is “Stereovision-Based 3D Planar Surface Estimation for Wall-Climbing Robots,” in which he used computer vision to create a program that would allow wall-climbing robots to acclimate to a surface based on its orientation, surface, and area.
Professor Tang was a 2013 Best Paper award nominee at the IEEE International Conference on Multimedia and Expo. That year, he also won, as co-advisor, Second Place for the Dean’s Prize of the CCNY Kaylie Entrepreneurship Competition for GesTherapy using hand gesture-based therapy to remodel physical rehabilitation. In 2016, he was a nominee for the H. Robert Schroeder Best Paper Award at the IEEE Integrated STEM Education Conference.
