We are excited to welcome three new faculty members to our department this year: Profs. Shagufta Mehnaz, Sarah Preum, and Hsien-Chih Chang! Read each of their brief bios below, or visit their websites for more details.
Shagufta Mehnaz is currently a Ph.D. candidate in the Department of Computer Science at Purdue University and planning to graduate in August 2020. She is broadly interested in the areas of security, privacy, and machine learning. Her research efforts develop novel machine learning techniques to protect data from different types of attacks (e.g., ransomware attacks and insider threats) as well as enhance the privacy and security of machine learning techniques and models themselves. She obtained her M.Sc. in Computer Science from Purdue University in 2016 and B.Sc. in Computer Science and Engineering from Bangladesh University of Engineering and Technology in 2013.
Sarah Preum is a Ph.D. candidate in the Department of Computer science at the University of Virginia, where she works with Professor John Stankovic. Sarah's research interest lies broadly in the intersection of artificial intelligence and cyber-physical systems, with a focus on increasing the safety and effectiveness of human-centric systems through information extraction and fusion. Sarah has developed novel natural language processing, knowledge integration, and temporal modeling techniques to provide personalized decision support for health safety. In the future, Sarah plans to develop fundamental techniques and theories for data-driven and knowledge-integrated information fusion for intelligent systems.
Hsien-Chih Chang is currently a postdoctoral researcher in theoretical computer science at Duke University. He obtained his Ph.D. from University of Illinois at Urbana-Champaign in 2018. His main research interests include discrete and computational topology and geometry, graph theory and algorithms, and applications to the rest of computer science. His current work focuses on applying topological tools to understand the efficiency of computation. Hsien-Chih will be joining the computer science department as a tenure-track faculty member at Dartmouth College in the coming fall.
