The SAND Lab (Systems, 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, undergrad researchers, and visiting scholars.


Congrats to our new PhD lab alumni: Xinyi Zhang, Shiliang Tang, and Zhijing Li, all defended in late May, early June and all headed to Facebook!

Congrats to our alumnus Gang Wang on his new position as Assistant Professor at UIUC Computer Science!

Congrats to Zhijing and Zhujun for their MobiHoc paper on spectrum anomaly detection!

SAND Lab finally gets a real lab logo!

Congrats to Bolun for (finally) defending his thesis and running off to join the evil empire Facebook!

Congrats to Bolun, Yuanshun, Shawn, Huiying, Bimal for their Oakland paper on defending DNNs against backdoor attacks!

Congrats to Bolun, Yuanshun and Bimal for their USENIX Security paper on transfer learning!

A huge congratulations to Professor Bimal Viswanath. Bimal will be joining Virginia Tech as tenure-track assistant professor this fall!

Congrats to Shiliang, Xinyi, Jenna and Miriam for their CSCW 2018 paper on gender bias!

Congrats to Yuanshun, Bimal, Jenna for their CCS paper on Automated Crowdturf Attacks using DNNs!
