This week, I had the pleasure of visiting #Snowflake's #Berlin office to share an overview of my past and ongoing #research.

As you can see in the photos, I’m doing my best to live up to the stage presence of my cartoon #cat self 😀

Last week at #EDBT2025 in Barcelona was a blast! Gave an invited talk (thanks #Huawei!), moderated a DEI panel, and co-organized a DEI tutorial. Wrapped it all up with experiencing the stunning architecture and cultural scene in the city 🏛️🌞.
