Hello there, I'm Oleg (he/him), I have a PhD in Astoronomy & Astrophysics, and I'm trying to be more down-to-Earth by working in Atmospheric Science.
In my free time, I can be found hyperfixating on whichever videogame I downloaded the day before.

Incredibly important work on indoor air pollution 👏 🧪
Really proud of this paper. Over the course of a year, we sampled PM2.5 in >300 houses in Bradford. This work package was led by myself and @profrosiemc.bsky.social and involved a dedicated team of atmospheric and health researchers

Radar data often includes information on aerial insect activity, which is often discarded, despite the fact that we don't know enough about movement and abundance of insects in the troposphere.📡 🐝 Our scientists are changing that. Very innovative use of radars in important & multidisciplinary work

UK weather radar is now being used to monitor trillions of insects in the sky every day – offering a new, cost-effective way to track biodiversity at scale.

An important article & research paper on environmental justice, indoor air quality and how it's unequal & inaccessible. eg if you aren't a homeowner. It highlights, among else, that work on indoor air quality should be done in a wider social & historical context, that contributes to the inequality.
Poor indoor air quality is linked to serious health problems, and the burden of these impacts is not evenly shared.

And I think this is a real problem. Presenting information in a "neutral" way that downplays/minimizes the conflicting ethical/moral dilemmas can make people less likely to respond to situations involving suffering; especially when it involves something even worse: forced, indiscriminate suffering 🧵
4. When you study these models by asking questions to test whether they are neutral, my question is this: does being neutral make the model more moral or ethical? What is the value of a model that responds neutrally to abuses or discrimination? n/n

True and there are several problems about this that several of us pointed out when we were working on these systems. Some are, these systems make up info even when summarizing, that it is statistically impossible to erase this & that the owner can train the info to tune it to its own bias... 1/n 🧵

I just can't catch a break. Last night, the police woke me up because two dudes tried stealing my motorcycle. They didn't succeed because: 1. A neighbour saw them and called the police; 2. The battery was dead, so they couldn't start it. Still, they rolled it away and smashed the front up 🥲
