APPLICATIONS OPEN NOW! Always wanted to learn about applied infectious diseases modelling? 💡Annual short course 15-26th September '25 🗓️ Application deadline for limited number of full scholarships 16th March ✏️Find out more & apply infectiousdiseasemodels.org/index.php

Like many others, I am now on BlueSky (@jdchallenger.bsky.social), I will be keeping both accounts active for the time being...

Hi All, We're going to try to switch over to BlueSky. Not sure exactly when, or whether the twitter autoposter will keep going. Please follow us here: bsky.app/profile/IDDjob…

My wish for the next election is that poll trackers look like the one on the right 👉 not the left This was yet another election where the polling showed it could easily go either way, but most of the charts just showed two nice clean lines, one leading and one trailing. Bad!

Malaria fights hard. We fight harder. 👊 Together, we can save 13.2 million lives in the next 15 years with innovations like vaccines, gene-drive tech, & new mosquito nets. 💉🕸️ Let's do this. #ZeroMalaria

Seriously?

Come work with us at Oxford PSI on vaccine trial modelling for pandemic preparedness! Multiple positions available. @PSIOxford @ChristoPhraser

In #Gaza, @WFP operations continue despite immense challenges, growing security risks & repeated evacuation risks. Each new evacuation disrupts vital services and delays critical support. The situation is dire—we urgently need a ceasefire to protect aid workers and civilians.

One of the areas I hope the new government can address is the difficulty many academics and researchers from low and middle income countries experience when trying to obtain a visa to visit the UK for scientific meetings. Applications are ofen delayed and sometimes even refused.

Are you a researcher studying the impact of #ClimateChange on #health? If so, keep an eye out in early July for our funding call opening! We'll be inviting pairs of mid-career researchers from sub-Saharan Africa & the UK to apply for up to £300k on a joint project. Stay tuned!

Not long left to register to vote in the UK General Election, link here: gov.uk/register-to-vo… Unusual to have a July election, so could catch out (e.g.) undergrad students who aren't registered to vote in their home constituency

This year's reading highlights included 'Cutting for Stone' by Abraham Verghese, 'The Candy House' by Jennifer Egan, 'Corregidora' by Gayle Jones & 'Cloud Cuckoo Land' by Anthony Doerr.

It's that time of year again! Many thanks to @haringeylibrary for tracking down several of these. Check out #MyYearInBooks @goodreads to discover the books I read in 2023 goodreads.com/user/year_in_b…

My notes of last night briefing on the situation in #gazastrip. @PalestineRCS appears to be the only actor that remains active. Aid is NOT reaching beyond Deir Al Balah according to PRCS. This is a highly concerning humanitarian leaving hundreds of thousands of people behind.

Deeply worrisome: 14 out of 36 hospitals and 2 specialty centers in #Gaza are non-functional due to lack of fuel as well as damage, attacks and insecurity. The hospitals that remain open are overloaded with 40% more patients than they are designed to manage. @WHO calls for urgent, sustained access at scale for humanitarian aid. We continue to call for the active protection of civilians and health care and for a humanitarian ceasefire.

We are hiring a postdoc to develop new methods for modeling and understanding viral load and serologic data based in the @PSIOxford. This is a 2.5 year post. Application deadline is 4th December. Please get in touch if you'd like to chat before applying! tinyurl.com/43b3p477

I’m pleased to share a pre-proof of our latest paper in Journal of Infection, led by @DrMahdiMoradi We identified mechanistic correlates of #SARSCoV2 viral load in the upper respiratory tract authors.elsevier.com/sd/article/S01… This was a great collaborative effort between many researchers

@yasisalek @frynaomifry One of the very best Bandsplains, this was so good!

You shut your mouth how can you say I go about podcasts the long way... The Smiths part 2 is up now with the son and the heir of everything in particular @frynaomifry Bigmouth strikes again: open.spotify.com/episode/6yMDo3…

I very much enjoyed #PAMCA2023 : not a typical conference! This was my first PAMCA conference, hopefully it won't be my last...

NEW EPISODE #ScienceInContext! This week @SabineLvE speaks with @JDChallenger about the impact of bacteria on the incidence of #Malaria👇 @imperialcollege @ThomasChurcher @GSK @JohnsHopkinsSPH @MEDINADiscovery @IrssF @ICE_Malaria
