🌍 New OpEd Alert! Biodiversity is not just an environmental issue — it's a health issue.
Yesterday, @cwalzer.bsky.social and I published an OpEd in @statnews.com calling for the health sector to confront a critical blind spot: biodiversity loss.

The UK isn’t prepared for the next pandemic – and nor are many other countries.

How a surge in ancient plagues 5000 years ago shaped humanity Plague, leprosy, smallpox and other diseases didn't jump from animals to humans when we thought. Ancient DNA is revealing where they come from and how they changed history

A wave of ancient plagues 5000 years ago changed everything — our DNA, immunity & societies.

Earlier this month, we welcomed the inaugural cohort of MPhil students in Global Risk and Resilience!

We look forward to supporting them as they begin an exciting year exploring the governance and mitigation of global catastrophic risks 🌍

It is incredibly exciting to have our first cohort of MPhil students starting this month. After what feels like an age of planning and admissions, we got to finally meet them on Wednesday, and what a fantastic group they are 🎉

🦠 New #Ebola outbreak declared in Kasai (DRC): 35 cases, 16 deaths so far.
Rapid response by @WHO, @UNICEF & partners underway.
A stark reminder of the need for strong #biosafety, #research infrastructures & preparedness.

We’re looking forward to welcoming the very first cohort of our MPhil in Global Risk and Resilience next week!
Ahead of the start of term, we’d like to reintroduce our education team.

Happy to share that I am starting a new position as Assistant Teaching Professor and Course Director of the MPhil in Translational Medical Research in @MedCambridge 🎉. Applications open on friday so do share in your networks www.med.cam.ac.uk/study/mphil-translational-medical-research

More details on #Ebola outbreak in DRC:
Index case was a pregnant woman (in third trimester), who came to Bulape General Reference Hospital on 20 August with fever, bleeding, bloody diarrhea. She died on August 25.
Then two health care workers, who first had contact with her, developed symptoms...

#Fieldepi training has set me up for a wonderful and varied career at the forefront of global health security.

At the same time I get to lead exciting research collaborations and projects focused on developing our abilities to detect and respond to infectious diseases in a time of conflict, climate change, and overall change.

I get to teach both our students in Cambridge as well as field epidemiologists across Europe and further afield.

My research focuses on epidemic and pandemic risks in a destabilised world. In my current job, I do research, build partnerships and bridges between researchers and practitioners, work on exciting research translation and capacity building projects and so much more.

Even better, shoe leather epidemiology and academic excellence are not mutually exclusive!
Interactions between #Fieldepi and academia can be mutually extremely enriching. I am a field epidemiologist and an Assistant Professor @cser.bsky.social @cam.ac.uk and fellow @downingcollege.bsky.social.

Happy #WorldFieldEpidemiologyDay #WFED2025! Field epi remains one of the most rewarding and challenging (in a good way) careers I can think of.
Field epidemiologists provide the evidence necessary for action, field epidemiology is the backbone of responding to a public health emergency.

Registration and the call for abstract submissions for #GHS2026 are officially open!

Do you have research, insights, or innovative work to share in advancing global health security? Submit your abstract and join us in Malaysia to be part of this vital global conversation.
