Career history
In the news
- They’ve taken the roads in” In the television series Father Ted (about three misfit priests living on a remote island off the west coast of Ireland), there is a notable scene where Mrs.Doyle declares that due to inclement weather, the island's roads had been disassembled and stored in a warehouse, rendering driving impossible. An incredulous Bishop Brennan, visiting briefly on diocesan business and who despises the island and its three priests, expresses his shock and dismay at being stranded, revealing that he is “meant to be in
- Two days left to apply for the Carbon13 climate venture builder Cambridge cohort 11. I simply cannot recommend it enough. On the 21st of July last year I got an email that has quite honestly changed my life. Simon Dierks, telling me I'd got a place on the Carbon13 venture builder in Berlin. I'd spent the previous 18 months trying to get a startup off the ground and had little to show for it beyond hard-won lessons and a lengthy list of emails telling me "better luck next time" or "it's not for us". Nothing was guaranteed by that
- Is bigger always better? 50 million images. 500 million images. 5 billion images. Most people judge a computer vision model by how many images it has seen. The rise of generative models may have coloured many people’s view of what an adequate data set is. Adequacy is defined by model performance in practice, not by training volume. For generative models, that kind of scale might make sense (technically speaking at least). They want to see everything, because they might be asked to create anything. Recognition and semantic models
- Sovereignty”, “autonomy”, “resilience”, “de-risking”, “onshoring”, "competetiveness", “security”: in recent years, these terms have become inescapable across European politics, trade policy, business and healthcare. The origins of this discourse trace back a decade and became more topical during Covid-19, but two intertwined events in September 2024 have acted as undeniable accelerants of its widespread adoption. The publishing of Mario Draghi's "Future of European Competitiveness" report, and, eight days later, the new European
- A peek into the future Decidius wants to build Last week, Anne Paduart and I attended the Flemish Government's ZIN complex in Brussels to pitch Decidius to Vlaio. While we were there, Anne pointed out that the building itself is one of the foremost examples of reuse in all of Europe. Ninety-five percent of the original towers' materials were preserved, reused, or recycled (63% onsite reuse, full breakdown in comments), thirty thousand tonnes of concrete aggregate among them, and ninety-five percent of the new office materials
- Grins and grey skies were the order of the day as I arrived into Liège-Guillemins station early on Friday morning (always an honourable mention on my list of favourite train stations in Europe). Dr. Anne Paduart and I were invited to present at the URMIBALI seminar organised and hosted by the University of Liège on the subject of Urban Mining and the development of novel methods to enable material reuse in Liege’s traditional buildings. A word of thanks to Sophie Trachte, Ophélie Noël and all of the organisers for a brilliant
