#52 – Michael Aird on how to do Impact-Driven Research
Michael Aird is a senior research manager at Rethink Priorities, where he co-leads the Artificial Intelligence Governance and Strategy team alongside Amanda El-Dakhakhni. Before that, he conducted nuclear risk research for Rethink Priorities and longtermist macrostrategy research for Convergence Analysis, the Center on Long-Term Risk, and the Future of Humanity Institute, which is where we know each other from. Before that, he was a teacher and a stand up comedian.
We discuss:
Whether you should stay in academia if you want to do impactful research
How to start looking for roles at impact-driven research organisations
What simple changes can improve how you write about your research
The uses of 'reductionism' and quantitative thinking
The concept of ‘reasoning transparency’
Michael’s experience investigating nuclear security

#51 – Kevin Esvelt and Jonas Sandbrink on Risks from Biological Research
A full writeup of this episode is available on our website: hearthisidea.com/episodes/esvelt-sandbrink.
Kevin Esvelt is an assistant professor at the MIT Media Lab, where he is director of the Sculpting Evolution group, which invents new ways to study and influence the evolution of ecosystems. He helped found the SecureDNA Project and the Nucleic Acid Observatory, both of which we discuss in the episode. Esvelt is also known for proposing the idea of using CRISPR to implement gene drives.
Jonas Sandbrink is a researcher and DPhil student at the Future of Humanity Institute. He is a fellow at both the Emerging Leaders in Biosecurity Initiative at the Johns Hopkins Center for Health Security, and with the Ending Bioweapons Program at the Council on Strategic Risks. Jonas’ research interests include the dual-use potential of life sciences research and biotechnology, as well as fast response countermeasures like vaccine platforms.
We discuss:
The concepts of differential technological development, dual-use research, transfer risks in research, 'information loops', and responsible access to biological data
Strengthening norms against risky biological research, such as novel virus identification and gain of function research
Connection-based warning systems and metagenomic sequencing technology
Advanced PPE, Far-UVC sterilisation technology, and other countermeasures against pandemics potentially worse than Covid
Analogies between progress in biotechnology and the early history of nuclear weapons
How to use your career to work on these problems — even if you don’t have a background in biology.
