Welcome!

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.

PhD Positions

In any normal year, we are usually looking to add 1-2 passionate and driven PhD students to the lab. However, because of an exceptionally big group of new PhD students in 2023 and 2024, we are not looking to recruit new PhD students for the 2024-2025 application cycle. You can still email us if you feel like you would be a fantastic fit for the lab, but we will likely only consider students who are truly exceptional.
