SAND Lab: Security, Algorithms, Networks and Data Welcome! Home Publications People Contact / Visit Us Sponsors The SAND Lab (Security, Algorithms, Networking and Data) at University of Chicago is co-directed by Professor Ben Y. Zhao and Professor Heather Zheng. Our research spans topics in security, machine learning, networked systems, HCI, data mining and modeling. Lab members includes (8-12) PhD and MS students, as well as undergrad researchers and visiting scholars. Join us! We are looking to add 1-2 passionate and driven PhD students to the lab in the 2021 application cycle! If you're interested, please fill out this little Google form so we can keep you on a short list of candidates, and make sure to mention Heather and Ben when checking boxes for faculty in your UChicago PhD Application. Latest If you're looking for the Fawkes tool for image privacy, go here for documentation, FAQ, technical paper and downloads. Total global downloads of the Fawkes photo cloaking tool hits 335,000 in January! Congrats to Yuxin, Zhuolin and the team for their upcoming CHI paper on User Authentication using EMS! Congrats to Kevin for filing his dissertation and joining ByteDance research! Onwards and upwards! Congrats to Shawn & Emily (co-first authors), Jiayun and Huiying for their USENIX Security paper on imaging cloaking for privacy against unauthorized machine learning models! Congrats to Kevin for accepting an offer to join ByteDance as a researcher on their Machine Learning Security team! Now just finish that thesis!!
