10¢ for your core philosophy in a tweet Max impact ⇒ mass harm prevention for relatively vulnerable & voiceless: 1. low-income countries (eg infectious diseases) 2. future generations (eg climate, ecosystem collapse) 3. sentient non-human life (eg decreasing meat & dairy)

"The data are consistent with hypothesis H" and "The data provide no evidence for hypothesis H" steer you in opposite directions but can mean the same thing: the data do not discriminate between hypotheses. Let's - explicitly consider multiple hypotheses - use clearer language

Great to have @adamjkucharski open the new @PSIOxford seminar series. Here discussing our decomposition of R(t) into contributing factors & other epi monitoring through the covid app, led by @mishkendall + @LucaFerrettiEvo, out last month ICYMI https://t.co/9LAQznlWpk

What are the big questions that emerge during new epidemics? And how do we answer them? @dr_anne_cori and I have put together a new review of inference of epidemic dynamics in the modern era, from understanding dynamics to evaluation of interventions:

Am I OK as a single-slide introductory explanation of phylogenetic trees, by analogy with more familiar family trees? Not much room to add more. Will have verbal explanation of the continuous model of genetic change. Reusing me with attribution = 👌

Stop using the widely-used discretised gamma rates model for your phylogenetics 👇

Crucial thread below. Several countries now have digital tools at the heart of their pandemic strategies, if they didn’t already (spoiler: these are countries that did relatively well against COVID). Meanwhile, many European countries seem to be taking a ‘play it by ear until

Popping up from mat leave 👋👶 to share our new paper in @ScienceMagazine. Anonymised data from the @NHSCOVID19app provided rich insights into the drivers of the epidemic, at remarkable speed. ➡️ Quick read: https://t.co/LtZcW9Qa2k ➡️ Full details: https://t.co/4pw5C3W0LL
