Lot's of excitement in the lab!

Nofar Carmeli for winning the Jacobs Scholarship. Well done Nofar!

Congratulations to Elad Kravi who gave his PhD seminar this week! Elad's work, titled "Understanding the Context of Microactions on the Web", was advised by Prof. Beny Kimelfeld and Prof. Yaron Kanza.

A new server has joined the lab computing infrastructure. The server, called Gaon7, has 500GB of RAM, and 64 CPU threads of the new Intel Scalable architecture (Xeon Gold). Happy processing!

The German Research Foundation DFG (Deutsche Forschungsgemeinschaft) has awarded a DIP grant to the project entitled "Quantitative Reasoning about Database Queries",  in collaboration with Prof. Martin Grohe.
