About Us

We are a group of founders, scientists, doctors, & policymakers who want to accelerate research to strengthen global resilience and reduce the likelihood of catastrophic pandemics. 

The AIxBiosecurity Fellowship is a new 8-week, full-time research programme dedicated to tackling biosecurity risks amplified by recent advances in frontier AI capabilities. We want to support early-career researchers investigate ways to reduce extreme risks from engineered and natural biological threats amid rapidly advancing biotechnology and emerging AI capabilities. Our fellowship is designed to meet this reality.

In her spare time, Grace enjoys running half marathons, vintage shopping and spending time with her cat Winston (and her fiancé).

  • Jonathan Dannevig

    Programme Director

    Jonathan is an engineer and economist with a Harvard MBA and 15 years of experience. He has been a consultant at BCG, twice an entrepreneur, and a policy officer at the UN. After realizing that his timelines were too optimistic, he decided to switch careers and is now the Program Director at ERA. He is married and has two kids (who are the main reason to work on AI risks), and he loves reading (from history and psychology to Victorian classics), travelling (he is the son of a pilot and a flight attendant), and football (River Plate and Argentina).

  • Genevieve Gaul

    Programme Associate

    Genevieve has experience in long-term project planning, workshop facilitation, and teaching. She first joined ERA as the Community Health Lead. Before this, she designed and organised a student development programme for a university, and studied Literature at Durham University. Outside of work, Genevieve enjoys undertaking various creative projects.

    Lennart Justen

    Research Manager

    Lennart is a Ph.D. candidate and Draper fellow at the MIT Media Lab and the Broad Institute, where he is co-advised by Kevin Esvelt and Pardis Sabeti. Lennart’s professional focus centers on biosecurity and pandemic preparedness, including work on airborne transmission suppression, pandemic early warning systems, and AIxBio risk mitigation. In AIxBio, he has worked on dual-use capability evaluations, including the Weapons of Mass Destruction Proxy (WMDP) and the Virology Capabilities Test (VCT) benchmarks, harm mitigation for biological design tools, and securing AI-assisted lab automation. Lennart has previously held positions at The Council on Strategic Risks, SecureBio, and the U.S. State Department.

  • Matt Smith Headshot

    Dr Matt Smith

    Research Manager

    Matt is a researcher working at the intersection of artificial intelligence and biosecurity, focused on mitigating catastrophic risks from emerging technologies. He earned his PhD in Molecular and Cellular Biology from the University of Washington under Nobel laureate David Baker, where he worked on computational protein design and enzyme engineering. Before entering AI policy, Matt spent several years at McKinsey & Company and later as a Senior Product Manager in Microsoft’s Security Division, specializing in cybersecurity and identity for sovereign cloud environments. He is currently an AI Policy Fellow with the Institute for AI Policy and Strategy and a Contributing Scholar at the Johns Hopkins Center for Health Security, where he works on AI‑biosecurity policy and threat‑assessment research.

  • Dr Christopher Stamper

    Research Manager

    Chris is an independent biosecurity researcher investigating the immunological risks of synthetic mirror life and the incorporation of non-canonical amino acids in protein diffusion models. He earned his PhD in Immunology from the University of Chicago, where he studied B cell responses to influenza and SARS-CoV-2. During his postdoctoral work at the Karolinska Institute, he explored immunogenetic networks at gut mucosal surfaces using single-cell RNA sequencing, bioinformatics, and machine learning. His consulting projects have included universal influenza vaccine design, AI safety and uplift, and benchmarking large language models for virological and immunological laboratory tasks.

  • Sam Smith

    Programme Associate

    Sam is Head of Courses at Leaf, where they focus on helping people discover their capacity for impact in AI safety and effective altruism. Alongside this, they've designed an introductory AI Safety course, facilitated programs like Non-Trivial, Leaf, and BlueDot, and organised EA Bristol alongside their studies in Maths and Philosophy. When they're not working on talent development, you'll find Sam bouldering, playing board and video games, or around a table for DnD.

  • Poppy Nevin-Adley

    Community Health Lead

    Poppy’s background is in entrepreneurship, NGOs, community-building, retreat/summit organization and data. She has degrees in both Human Rights and Marketing. She loves helping people find impactful opportunities and creating safe spaces for community to flourish. She spends her free time traveling, volunteering, singing and dancing.

  • Ruqaiya Takreem

    Operations Associate

She is a licensed advocate with the Bar Council of India and holds an MSc in Refugee and Forced Migration Studies from the University of Oxford, where she was a High-Impact Career Scholar and a Bonavero Institute Fellow. She has worked across India, Lebanon, the US, and the UK on legal, policy, and operational projects. Her interests lie at the intersection of legal alignment of AI, governance and institutional design, particularly mitigating catastrophic risks like authoritarian misuse of advanced AI. Beyond ERA, she is an EA-aligned founder and mentor, building talent pipelines to support Global South researchers and professionals into high-impact careers.

  • Oscar Lloyd

    Operations Contractor

    Oscar is a philosopher studying AI Ethics at Cambridge with a background in ethics and moral cognition. They are currently working on risks with automated decision-making and have previously presented on metaethical issues with decision-making using LLMs. When not researching, Oscar can be found playing classical violin and fiddle, hiking, and organizing with various community groups around Cambridge.

Our Partnership

The AIxBio Research Fellowship is run by ERA, in partnership with the Cambridge Biosecurity Hub.


ERA runs one of the world’s largest, longest-running AI safety and governance talent programmes in the world. We are a talent organisation founded by Cambridge alumni, and based at Cambridge, UK, with strong ties to the University of Cambridge. We support researchers and entrepreneurs working to mitigate risks from frontier AI. So far, ERA’s mission has been largely manifested through our annual ERA:AI fellowship programme.

In 2025, we ran a Summer ERA:AI Research Fellowship, hosted 30+ speakers & workshops over the 8 weeks, ran a Technical AI Governance Forum, and co-organised the 2025 Vegas AI Security Forum. You can see some of our past research here. Over the past 5 years, we have supported over 120 early-career researchers from 10+ countries through our research fellowship and conferences, leading to high counterfactual impact on their careers. We provide our fellows with mentorship from organisations such as UK AISI, CAISI, RAND, GovAI, Google Deepmind etc., and our alumni have gone on to lead work at impactful institutions in this space. 

The Cambridge Biosecurity Hub (CBH) is a team of researchers investigating and raising awareness of the risks associated with rapidly developing biotechnologies. We help people learn more about biosecurity and impactful career pathways into AIxBio, while building a supportive community for those working to reduce pandemic risk.
CBH has run a number of projects, including 'Biosecurity Fundamentals' reading groups, an 8-week speaker series, and biosecurity research sprints.

Our largest event to date was the inaugural Cambridge Pandemic Prevention Symposium on October 7, 2024, which brought together over 100 attendees, including experts, academics, and industry professionals from across the UK, for discussions spanning key areas in pandemic policy and technical interventions.
