Smriti Bhatt is an Assistant Professor of Computer Science in the Department of Computing and Cyber Security at Texas A&M University-San Antonio. She has received her Ph.D. in Computer Science from the University of Texas at San Antonio and did her doctoral research at the Institute for Cyber Security (ICS) and Center for Security and Privacy Enhanced Cloud Computing (C-SPECC). Dr. Bhatt's research expertise is in the field of Cyber Security, mainly focused on Access Control and Communication Control models, and Security and Privacy in Cloud Computing and the Internet of Things (IoT). Her current research projects focus on developing secure access control and communication control models for Cloud-Enabled IoT architecture applicable to various IoT domains, such as Smart Home, Smart Health, and Wearable IoT. Her research work also expands into deep learning for IoT security with applications in access control and anomaly detection. She has been actively publishing her work on well-regarded conferences and journals in the field, and also continually serves as an expert reviewer for journals (e.g., IEEE Transactions on Cloud, IEEE Access, and Transactions on Dependable and Secure Computing). She have also served as technical program committee member and co-chair for several conferences and workshops. Furthermore, Dr. Bhatt is enthusiastically involved with various national and local organizations including AnitaB.org, Women in CyberSecurity (WiCyS), and San Antonio Women in IT (SAWIT) for enhancing diversity and inclusion in STEM.

Asma Alshehri is an Assistant Professor in Computer Science at Shaqra University, Shaqra, Saudi Arabia. She received M.S. and Ph.D. in Computer Science from the University of Texas at San Antonio (UTSA). It was her honor to be the first Arabian women to work and graduate from the Institute for Cyber Security (ICS), UTSA. Her primary area of research includes security and privacy in cyber space focused in studying foundational aspects of access control and their application in technologies including cloud computing, IoT and Big Data. She has worked in developing novel security mechanisms, models, and architectures for IoT smart cities, cars, and homes. She is also interested in malware analysis and AI assisted cyber security solutions. She is currently the Vice Dean of IT and E-learning Deanship at Shaqra University, Head of E-learning Unit at University Agency for Educational Affair, and Chair of Computer Science Department at Collage of Science and Humanities at Dhurma. She holds a B.S. degree in Computer Science from Princess Nourah Bint Abdulrahman University, Riyadh, Saudi Arabia

Ravi Sandhu is Professor of Computer Science, Executive Director of the Institute for Cyber Security and Lead PI of the NSF Center for Security and Privacy Enhanced Cloud Computing at the University of Texas at San Antonio, where he holds the Lutcher Brown Endowed Chair in Cyber Security. Previously he served on the faculty at George Mason University (1989-2007) and Ohio State University (1982-1989). He holds BTech and MTech degrees from IIT Bombay and Delhi, and MS and PhD degrees from Rutgers University. He is a Fellow of IEEE, ACM and AAAS, and has received numerous awards from IEEE, ACM, NSA, NIST and IFIP, including the 2018 IEEE Innovation in Societal Infrastructure award for seminal work on role-based access control (RBAC). A prolific and highly cited author, his research has been funded by NSF, NSA, NIST, DARPA, AFOSR, ONR, AFRL, ARO and private industry. His seminal papers on role-based access control established it as the dominant form of access control in practical systems. His numerous other models and mechanisms have also had considerable real-world impact. He served as Editor-in-Chief of the IEEE Transactions on Dependable and Secure Computing, and previously as founding Editor-in-Chief of ACM Transactions on Information and System Security. He was Chairman of ACM SIGSAC, and founded the ACM Conference on Computer and Communications Security, the ACM Symposium on Access Control Models and Technologies and the ACM Conference on Data and Application Security and Privacy. He has served as General Chair, Steering Committee Chair, Program Chair and Committee Member for numerous security conferences. He has consulted for leading industry and government organizations, and has lectured all over the world. He is an inventor on 31 security technology patents and has accumulated over 45,000 Google Scholar citations for his papers. At UTSA his team seeks to pursue world-leading research in both the scientific foundations of cyber security and their applications in diverse 21st century cyber technology domains, including cloud computing, internet of things, autonomous vehicles, big data and blockchain. Particular focus is on foundations and technology of attribute-based access control (ABAC) as a successor to RBAC in these contexts
