MARS 4.0
MARS (Mentorship for Alignment Research Students) connects aspiring researchers - from students to professionals - with experienced mentors to conduct AI safety research. Over 2-3 months, participants work on focused projects in technical or governance/policy domains, part-time, on a volunteer basis.
MARS 4.0 features an expanded governance and journalism track, with participants in previous iterations going on to publish their work at venues such as NeurIPS, ICML, EMNLP & ControlConf, as well as policy outlets and think tanks. Past mentors include researchers from Redwood Research, Apollo Research, Google DeepMind, University of Cambridge, Centre for AI Safety, UK AI Safety Institute, and other leading institutions.
MARS 4.0 will run from December 1st to early-mid February 2026, with two separate batches of in-person weeks in Cambridge, UK (December 1st-6th and December 8th-14th), followed by a remote mentorship phase.
Application deadline: 1st October, 23:59, Anywhere on Earth time.
(For both participants entering Stage I. and mentor applications.)

Program Details
MARS (Mentorship for Alignment Research Students) connects participants with experienced mentors to conduct AI safety research from December 1st to early-mid February 2026. Over this period, participants work on focused projects in either technical or policy domains.
Why apply?
Work directly with experienced AI safety researchers on research projects
Join an intensive week in Cambridge (UK) with workshops, speakers, and accommodation provided
Receive regular mentorship and project support throughout the program
Opportunity to publish your work (previous participants have published at EMNLP, NeurIPS, ICLR, and on arXiv)
Connect with a community of researchers interested in AI safety
Format & Time Commitment
MARS begins with two separate batches of in-person weeks in Cambridge, UK (December 1st-6th and 8th-13th), where participants come together to kick off their projects. We provide accommodation, meals, and travel support (~$200 for participants & mentors traveling from the UK/EU, ~$650 for longer flights) during this period.
Following the in-person week, research continues remotely until February 2026. Teams meet weekly with their mentors and research managers, devoting approximately 8 hours per week to their projects. For teams based in Cambridge, Oxford, or London, we also organise optional in-person co-working sessions.
Throughout the program, CAISH provides hands-on support to help teams develop their research, culminating in final project presentations in February 2026.
Participation in the program is not paid, and is understood to be undertaken on a volunteer basis as a learning opportunity.
Application Process
The application deadline for the general application is October 1 at 23:59 Anywhere on Earth. We aim to contact all applicants within two weeks of the deadline.
Candidates who pass Stage I will be invited to Stage II. This stage may include an asynchronous interview and mentor-specific applications, which can take up to two hours per mentor. Applicants will have one week to complete these.
Following Stage II, mentors may invite selected candidates for additional interviews or tests. Final decisions will be announced by November 1.

Time Commitment
Participants should expect to each spend 8-15+ hours/week on their project, depending on the project chosen.
Weekly Check-Ins
Throughout the duration of the program, you are expected to check-in:
With your teammates once a week. It'll be up to your team to coordinate meeting times or create co-working systems.
With your supervisor once a week.
The format of check-ins with your supervisor will be at their discretion.
We will also have program-wide events and check-ins, including socials, co-working sessions, and guest speakers. More details on these events will be announced to accepted participants.
MARS Research Symposium
This event will take place in ~early-mid February, where each research group presents their research.
