Research on HCI and Social Computing at Lehigh covers a broad range of issues in the relationships between humans, computing, and society. Examples include information visualization, social media design, human interactions with AI/ML systems, and social privacy practices, to name a few. This work addresses complex, pressing sociotechnical issues, such as harassment detection and prevention, online political engagement, and resistance to technology development. Students in the graduate program of Computer Science conduct cutting-edge research in a variety of fields including database and information systems, Internet search, graphics, user interfaces, Web-based systems, multimedia and image processing, bioinformatics, intelligent systems, computer architecture, robotics, secure systems, networks, embedded systems, and mobile computing. Beyond these areas, faculty and graduate students explore interdisciplinary aspects of computer science research through interactions with colleagues in other departments at Lehigh, at other universities, and at corporate research labs. Within Lehigh, collaborations are underway with researchers from all four colleges in areas such as biological sciences, design arts, sociology, management, marketing, economics, and education, as well as the departments of Civil and Environmental Engineering, Electrical and Computer Engineering, Industrial and Systems Engineering, and Mechanical Engineering and Mechanics.
