About Me

This is Shirin Nilizadeh, Assistant Professor at the Department of Computer Science and Engineering, University of Texas at Arlington. I received my Ph.D. in Security Informatics from the Indiana University Bloomington. For my dissertation on Privacy-aware Decentralized Architectures for Socially Networked Systems, I received a two-year fellowship from the School of Informatics and Computing at IUB. Following my doctorate, I did postdocs in PrivacyLab and CNets at Indiana University Bloomington from 2014-2015, in SecLab at UC Santa Barbara from 2015-2017, and then in CyLab at Carnegie Mellon University from 2017-2018.

My research focuses on security and privacy in the context of systems and social networks using techniques from machine learning and big data analytics. In particular, my research has two main aspects:
(a) designing techniques and building systems to protect security and privacy of users and to give users more control over their data; and,
(b) analyzing data to identify and characterize new security and privacy threats, and to capture insights and quantify aspects of human online behavior reacting to the existing threats.

I have served on program committees of the Privacy Enhancing Technologies Symposium (PETS) 2016-2018, Workshop on Privacy in the Electronic Society 2018, ACM Asia Conference on Computer and Communications Security (ASIACCS) 2017, and World Wide Web Conference (WWW) 2016. I have also reviewed many journal papers submitted in Transactions on Information Forensics and Security, Transactions on Dependable and Secure Computing, Journal of Computer Science and Technology, and Human-centric Computing and Information Sciences.
