Working on biosecurity research around far-UVC safety. Organized EA Munich for >2 years and did some EA community building in Germany. Studied 3 years of medicine. Incoming master's student in Genomic Medicine at Oxford.

Sometimes I write about meditation and other stuff. You can find my writing on my website or on Substack:

How others can help me

How I can help others

  • Give insights about my path from med student → independent biosecurity research → full-time biosecurity research
  • Give learnings from organizing EA Munich.
  • Besides that, I have some expertise in medicine, meditation & well-being, and effective learning techniques.


Topic contributions

It's fantastic to see that this is public now; thanks, Lin!

Brilliant work, as always; thank you! It is great to easily access these graphs and the infographic for future "intro to biosecurity" or similar presentations. 

FYI, the review paper that I teased in the introduction has finally been published and is now freely available online. It goes over existing far-UVC skin and eye safety evidence and sketches out important studies that should be done in the future.

Also, check out these X threads on the paper by Lenni Justen and Kevin Esvelt

I didn't know that! Thanks for the info.

In the meantime, I have created an MVP google doc of the biosecurity landscape. 

Thanks, Luca!

You are correct that there are no results yet since the trial is still ongoing and double-blinded. I have talked to them about their trial and attended that talk. AFAIK they decided to extend the duration of the trial and are adding another study site (long-term care facility) since they received additional funding for a phase 2. 

In this next phase of the trial, they will also be monitoring ozone and volatile organic compounds, which could provide some useful real-world data about those questions. 

Another data point from a post on Reflective Altruism about biorisk:

This post begins a sub-series, “Bioriskarguing that levels of existential biorisk may be lower than many effective altruists suppose.

I have to admit that I had a hard time writing this series. The reason for that is that I’ve had a hard time getting people to tell me exactly what the risk is supposed to be. I’ve approached high-ranking effective altruists, including those working in biosecurity, and been told that they cannot give me details, because those details pose an information hazard. (Apparently the hazard is so great that they refused my suggestion of bringing their concerns to a leading government health agency, or even to the CIA, for independent evaluation). One of them told me point-blank that they understood why I could not believe them if they were not willing to argue in detail for their views, and that they could make do with that result.

A related point that I have observed in myself: 

I think dual-use technologies have a higher potential for infohazards. I have a preference for not needing to be "secretive," i.e., not needing to be mindful about what information I can share publicly. Probably there is also some deference going on where I shied away from working on more infohazard-y seeming technologies since I wasn't sure how to deal with selectively sharing information. Accordingly, I have preferred to work on biorisk mitigation strategies that have little dual-use potential and, thus, low infohazard risk. (In my case far-UVC, another example would be PPE).

The problem with this is that it might be much more impactful for me to work on a biorisk mitigation technology that has more dual-use potential, but I haven't pursued this work because of infohazard vibes and uncertainty about how to deal with that. 

Another difficulty, especially for junior people, is that working on projects with significant infohazard risk could prevent you from showing your work and proving your competence. Since you might not be able to share your work publicly, this could reduce your chances of career advancement since you (seemingly) have a smaller track record. 

(Side note: it's always both flattering and confusing to be considered a "senior member" of this community. I suppose it's true, because EA is very young, but I have many collaborators and colleagues who have decade(s) of experience working full-time on biorisk reduction, which I most certainly do not.)

I think part of this is that you are quite active on the forum, give talks at conferences, etc., making you much more visible to newcomers in the field. Others in biosecurity have decades of experience but are less visible to newcomers. Thus, it is understandable to infer that you are a "senior member."

I agree with Jasper and don't expect impacts on the skin microbiome to be a big deal, but it would, of course, be good to get some more data. 

One useful comparison is that healthcare workers use alcohol-based hand sanitizers many times a day, which are quite potent and can kill microbes in areas inaccessible to Far-UVC. 

In this review paper, they only saw changes to the composition of the skin microbiome after extremely frequent daily hand disinfection: 

“Overall microbe diversity on hands was unchanged with alcohol-based hand rub use or hand washing, with the exception that overall diversity was lower in those that reported >40 hand washing with soap and water events per shift”

From Edmonds-Wilson et al. 2015. I don't know how bad reduced diversity is and what harmful effects that might have. 

While these alcohol-based hand sanitizers are quite effective, they evaporate quickly and accordingly kill microbes in a very short time span. In certain scenarios, you could imagine far-UVC being different because it could kill off skin microbes at the back of your hands more or less continuously during the ~8 hours you are at work. This raises the question if this mode of continuous disinfection has different effects than the short bursts of frequent hand disinfection experienced by healthcare workers. I'd be surprised if the outcome is very different.
