MASDS Peer Ambassadors

The Peer Ambassador Program provides current MA Statistics & Data Science students with meaningful leadership opportunities to support the department’s academic community.
Ambassadors serve across two specialized focus areas:
- Outreach: Represent the program at recruitment events and engage with prospective students to share insights about the MA experience.
- Community Building: Plan and facilitate internal activities that strengthen peer connections and foster a welcoming, inclusive environment for the current cohort.

Abhishek Sai Shukla
I'm Abhishek, a Master's student in Statistics who recently moved from Bangalore to Berkeley. When I'm not working through datasets, I'm usually doing improv, exploring new neighborhoods, or getting into conversations about movies, culture, or whatever random topic comes up.
I'm excited to help create a community where people feel comfortable being themselves—whether that's sharing study tips, grabbing food together, or just having those spontaneous conversations that make everything feel a bit more connected.
