PI Biographical Information

Patrick McDaniel Patrick McDaniel is a Professor in the Computer Science and Engineering Department at The Pennsylvania State University and co-director of the Systems and Internet Infrastructure Security Laboratory. Patrick's work on telecommunications security has uncovered serious vulnerabilities in the structure of the existing cellular network. His reported vulnerabilities relate to the misuse of text messaging to congest control channels on the "over-the-air" protocols, thereby preventing the delivery of legitimate voice and data. Working with cellular providers and national carriers, he has extended this work to 3G data services and uncovered similar problems in new standards. Patrick has worked with the FBI, FCC, DHS, Lucent, and has sat on the President's National Security Telecommunications Advisory Committee (NSTAC) helping craft national telecommunications public policy. Patrick also actively participates in national debates on important public policy issues. He was named the principal investigator of the EVEREST project analyzing the security of voting systems used in Ohio. Working directly with the Ohio Secretary of State and leading teams from Penn State, the University of Pennsylvania, and the University of California-Santa Barbara, he directed source code and red-teaming efforts used to illuminate security issues in voting systems and to assess the effectiveness of technical and procedural countermeasures addressing flaws. Extending previous reports in Florida and California, the vulnerabilities and procedures revealed in this 300+ page report directly informed the election procedures used nationwide in the 2008 Presidential election.

Patrick was the editor-in-chief of the ACM Journal Transactions on Internet Technology (TOIT), and served as associate editor of the journals ACM Transactions on Information and System Security and IEEE Transactions on Computers, and IEEE Transactions on Software Engineering position. Patrick was awarded the National Science Foundation CAREER Award and has chaired several top conferences in security including, among others, the 2007 and 2008 IEEE Symposium on Security and Privacy and the 2005 USENIX Security Symposium.

Prior to joining Penn State, Patrick was a Senior Research Staff Member at AT&T Research in Florham Park, NJ.


Lujo Bauer is an Associate Research Professor at Carnegie Mellon University, with joint appointments in CyLab and the Electrical and Computer Engineering Department. His interests span many areas of computer security, including building usable access-control systems with sound theoretical underpinnings, developing languages and systems for run-time enforcement of security policies, and generally narrowing the gap between a formal model and a practical, usable system. Bauer is active in both the traditional computer security community and in the usable security community, recently chairing conferences such as ACM's Conference on Data and Application Security and Privacy (CODASPY) in 2013, the Internet Society's Network and Distributed Systems Security Symposium (NDSS) in 2014, and co-chairing the Symposium on Usable Privacy and Security (SOUPS) in 2013 and 2014. Some of Bauer's most-cited research focuses on achieving fundamental theoretical understanding of the capabilities of enforcement systems, including in distributed settings, and on developing practical mechanisms that can be formally shown to correctly enforce desired policies. This foundational approach will be leveraged when developing algorithms for agility to aid in automatically generating configuration options that satisfy desired global constraints. Bauer's research in designing and improving the efficacy of user interfaces for security provides a good starting point for addressing aspects of the human element that is a key part of attack detection.

Jean Camp is a founder of the interdiscipline of economics of security, with expertise in both rational and behavioral economics of security. Her c ore contributions are in area of the interaction between organizational, human, and economic factors with technologies of security and privacy, otherwise know as risk. Her work on risk assessment has included analysis of macro level variables in cases of spam and malware; risk pricing for authorized users; and incentive-based management of users as well as defenders. She is a pioneer in security interaction as risk communication, and implemented the first work on mental models in computer security. She builds on the economics and psychological literature in order to embed heuristics and biases in human decision making proactively in the design of secure systems. Professor Camp is the author of “Trust and Risk in Internet Commerce” (MIT Press), “Economics of Identity Theft” (Springer) and the editor of “Economics of Information Security” (Kluwer Academic). She has authored over one hundred fifty peer-reviewed works, in addition to selected or invited works, and tens of book chapters. She has made scores of invited presentations on five continents. Her patents are in the area of privacy-enhancing technologies. Prof. Camp's trajectory is uniquely interdisciplinary, as began her graduate studies in electrical engineering in North Carolina before moving to the Department of Engineering and Public Policy at Carnegie Mellon to complete her PhD in Engineering and Public Policy. Upon graduation she became a Senior Member of the Technical Staff at Sandia National Laboratories. She left Sandia National Laboratories for eight years as a professor at Harvard's Kennedy School, departing to lead the security group in the newly-formed School of Informatics at Indiana University.


Nicolas Christin is an Assistant Research Professor of Electrical and Computer Engineering at Carnegie Mellon University, and is affiliated with CyLab, Carnegie Mellon University's security lab. He also has courtesy faculty appointments in Engineering and Public Policy, and in the Information Networking Institute. He holds a Diplôme d'Ingénieur from École Centrale Lille, and M.S. and Ph.D. degrees in Computer Science from the University of Virginia. His research interests are in computer and information systems networks; most of his work is at the boundary of systems and policy research, with a slant toward security aspects. He has most recently focused on online crime, security economics, and psychological aspects of computer security. He equally enjoys field measurements and mathematical modeling. His work on applications of game-theory to security decision-making has been extensively cited, and his work on measurements of online criminal activity has garnered significant attention from the popular press (with NPR, Forbes, or the Economist among others citing various research efforts Christin led), but more importantly, helped the research community design much more accurate models of attacker behavior. Finally, his recent work on password authentication (with Cranor and Bauer among others) is a successful example of human dynamic modeling (user studies) integration with network measurements and mathematical analysis (e.g., comparison of entropy calculations with actual guessability).


Lorrie Faith Cranor is an Associate Professor of Computer Science and of Engineering and Public Policy at Carnegie Mellon University where she is director of the CyLab Usable Privacy and Security Laboratory (CUPS) and co-director of the MSIT-Privacy Engineering masters program. She is also a co-founder and scientific advisor of Wombat Security Technologies, Inc., a leading provider of cyber security training and filtering solutions. Dr. Cranor came to CMU in December 2003 after seven years at AT&T Labs-Research. Dr. Cranor has played a key role in building the usable privacy and security research community. She co-edited the seminal book Security and Usability, and founded the Symposium On Usable Privacy and Security (SOUPS). She also directs an NSF-funded Integrative Graduate Education and Research Traineeship (IGERT) program on usable privacy and security. Dr. Cranor has conducted pioneering research that investigates cyber security challenges while considering humans as an integral part of the system under consideration, rather than a secondary constraint. She has led research efforts focused on reducing susceptibility to phishing, making access control systems easier to configure and less susceptible to human error, improving the effectiveness of cyber trust indicators and warnings, and developing password policies grounded in empirical data. Her 2008 framework for reasoning about the human in the loop offers a systematic model for investigating human behavior in a secure system.


Cleotilde Gonzalez is an international leader in behavioral and computational research of Dynamic Decision Making. She investigates experience-based decision making, with experimental and computational cognitive modeling methods, to determine when and how individuals rely on experience to make decisions and how experience helps them adapt to novel situations. Together with her colleagues, she developed a theory of learning and decisions from experience in dynamic tasks, called Instance-Based Learning Theory (IBLT). IBLT is represented computationally in a number of cognitive models that make accurate predictions and provide additional theoretical insights on experience-based decision making within a cognitive framework. IBLT was originally developed with the support of the Army Research Laboratories, Advanced Decisions Architectures, Collaborative Technologies Alliance (ARL, ADA-CTA), a program in which Prof. Gonzalez was a lead PI. IBL models have been developed in a wide range of real-life contexts, and recently in cyber-security. IBL models rely of learning and memory mechanisms from the well-known ACT-R cognitive architecture. The cyber-security models emerged from a MURI grant on cyber situation awareness, by the Army Research Office (ARO). Prof. Gonzalez has proposed a theoretical framework to extend IBL models that integrate adversary-defender interactions through Behavioral Game Theory (BGT). Prof. Gonzalez has started to use IBL-BGT models to study cyber warfare and to investigate development of trust in the Network Sciences, ARL- CTA.
