Dr. Wenhai Sun is an Assistant Professor in the Department of Computer and Information Technology at Purdue University. He holds two PhD degrees in Computer Science from Virginia Tech, US and in Cryptography from Xidian University, China. His research covers various security and privacy issues in networked information systems and cyber-physical systems, including cloud computing, IoT, blockchains, computer/mobile systems, and wireless network. He developed enabling techniques to secure the critical and fundamental cloud services, i.e. data search and deduplication, over encrypted storage while maintaining their usability and efficiency by applying a multi-disciplinary approach, including cryptography, storage management, information retrieval, computer system and networking, and programing language. The major results of his research have been published in prestigious journals, e.g. IEEE Transactions, and top security and networking conferences, such as ACM ASIACCS, IEEE INFOCOM. He received the Distinguished Paper Award from ACM ASIACCS 2013. He was also the recipient of Pratt Fellowship from Virginia Tech. He has served as the reviewer for more than thirty journals and conferences. In addition, he was a full-time advisor for mentoring undergraduate students at Xidian University.
