Jungwoo Ryoo is the Head of the Division of Business, Engineering, and Information Sciences and Technology (BEIST) and Professor of Information Sciences and Technology (IST) at the Pennsylvania State University-Altoona. Ryoo is also a graduate/affiliate faculty member of the college of IST at Penn State. He is a technical editor for the IEEE Communications Magazine and also working with IEEE and Software Engineering Institute (SEI) as a consultant. His research interests include information security and assurance, software engineering, and computer networking. He is the author of numerous academic articles and conducts extensive research in software security, network/cyber security, security management (particularly in the government and medical sector) and auditing (especially in cloud computing), software architectures, architecture description languages (ADLs), object-oriented software development, formal methods, and requirements engineering. Many of Ryoo's research projects have been funded by both state and federal government agencies. He also has substantial industry experience in architecting and implementing secure, high-performance software for large-scale network management systems. He received his Ph.D. in Computer Science from the University of Kansas in 2005.

Research Interests:

My research focuses on the security aspect of information sciences and technology. More specifically, I am seeking innovative ways to specify and design secure software and to detect security hot spots in the source code, using architectural and ontological concepts. I also investigate the impact of human factors on the information security readiness of various organizations. The research I conduct has direct applications to everyday life problems including management of security threats, information security readiness assessment, identity theft prevention, wireless and mobile security, and the development of software with less security vulnerabilities.
