Systems, Algorithms, Networks and Data
The SAND Lab (Systems, Algorithms, Networking and Data) at UCSB is co-directed by Professor Ben Y. Zhao and Professor Heather Zheng. Our research spans topics in networked systems, social networks, wireless networks, security, data mining and modeling. Lab members includes (8-9) PhD and MS students, undergrad researchers, and visiting scholars. For prospective students interested in joining the lab, please read this FAQ on UCSB, and then our lab information here.
We're thrilled that an exceptional group of new students will be joining SANDLab this fall (2014), including Zhijing Li, Bingjie Liu, Shiliang Tang, Da Zhang, Xinyi Zhang, and Yanzi Zhu. This is an extraordinarily large incoming group for our lab, and we're very excited for your arrival!
Research at the SAND lab encompasses topics across multiple areas, most heavily centered around three core areas: wireless and mobile systems, social networks: measurements and security, and graph analysis and modeling.
