Constellation Astra Fellowship

Astra is Constellation’s flagship fellowship, built to accelerate AI safety research and talent.
AI is advancing faster than any technology in history, and we think it's worth preparing for some of its most concerning risks. Astra helps close this gap by bringing exceptional people into the field and connecting them with leading mentors and research opportunities.

Program Overview

Astra is a fully funded, 3-6 month, in-person program at Constellation’s Berkeley research center. Fellows advance frontier AI safety projects with guidance from expert mentors and dedicated research management and career support from Constellation’s team.

Over 80% of Astra’s first cohort are now working full-time in AI safety roles in organizations such as Redwood Research, METR, Anthropic, OpenAI, Google DeepMind, the Center for AI Standards and Innovation, and the UK AI Security Institute. This round, we want to go further: placing even more people into the highest-impact roles, and helping fellows launch new initiatives to tackle urgent but neglected problems.

Mentors & research areas

Governance & policy:

Advances policy research to clarify strategies for mitigating critical risks from powerful AI systems.

Additional mentors from leading AI policy think-tanks

Security:

Investigates AI-related security risks, including related vulnerabilities, misuse, and failure modes.

Additional mentors from leading AI security institutions.

Field building:

Helps build the AI safety field’s capacity by addressing talent and coordination gaps, launching new projects, and convening key decision-makers.

“Astra was a really important program for us. We first started working with Daniel Kokotajlo through Astra, and the scenario we started developing during the program eventually became AI 2027. After Astra, we also co-founded the AI Futures Project together.”

Authors on AI 2027 & AI Futures Project Co-founders

"I worked with METR during Astra, and joined METR’s policy team immediately after the fellowship. Participating in Astra directly led to my current role.”

Michael Chen

Member of Policy Staff, METR

“Astra was an incredibly important opportunity. I was able to work closely with my mentor Buck, who taught me a lot about doing good research. That eventually led me to my role at Redwood Research, where I now run an entire team.”

Aryan Bhatt

Researcher, Redwood Research

"I'm really glad I participated in Astra! Endless conversations (both with my mentor and everyone else at Constellation), ranging from theoretical alignment to frontier governance, were an invaluable source of learning, knowledge and opportunities."

Martin Soto

Technical Staff, UKAISI

  • Mentorship & Research Management:
  • Weekly mentorship from senior experts and research management support from Constellation’s team (via 1:1s, small group meetings, office hours, Slack collaboration).
  • Placement Services:
  • Many fellows are expected to join organizations that are participating in Astra. Others are actively connected to opportunities across our network.
  • Incubation Services:

Who we’re looking for

We’re looking for talented people that are excited to pursue new ideas and projects that advance safe AI. 

You may be a strong fit if you:

  • Are motivated to reduce catastrophic risks from advanced AI
  • Bring technical or domain-specific experience relevant to the focus areas (e.g., technical research, security, governance, policy, strategy, field-building) 
  • Would like to transition into a full-time AI safety role or start your own AI safety focused organization

Prior AI safety experience is not required. Many of our most impactful fellows entered from adjacent fields and quickly made significant contributions. If you're interested but not sure you meet every qualification, we’d still encourage you to apply.
