Epidemiology PhD, MPH --- interested in infectious disease dynamics and novel surveillance systems

I will be advertising a funded PhD studentship shortly, for a project on adding psychological theory (social identity) to modelling of epidemics ( @leverhulme.ac.uk funded, with Marijn Stok). The studentship will start in January 2027. Get in touch now for informal enquiries.

I'm excited to share a preprint that's been years in the making: the idea took shape during the COVID pandemic. Anecdotally, people would sometimes spread COVID at work but not at home, and vice versa. Why? One explanation would be if infectiousness is fleeting...

How bursty infectiousness shapes epidemic dynamics

An epidemic’s expected course is determined by the magnitude and timing of a typical person’s infectiousness — captured, in turn, by the basic reproduction number and the generation-time distribution....

Again total misunderstanding of public health surveillance. FoodNet monitors trends, cyclospora is still on NNDSS which with CDC budget cuts/stagnation especially regarding ELC directly impacts state capacity. And the same issue with FSIS. Congress really needs an epidemiologist.

Sen. Ossoff slams HHS Secretary RFK Jr. after he terminated the CDC's required surveillance of the parasite causing cyclosporiasis: "Your foolish and self-indulgent demolition of critical public health programs puts Americans at risk. The Trump Administration is actively undermining food safety."

The trouble with articles like these is that they never come close to the nuance required to understand the difficulty and bottlenecks. The Dr. Barratt interview was distilled to "staff cuts at lab". Okay, explain what DPDM lab does. What does FoodNet do? NORS? FSIS? DCIPHER? Multiplex panels?

If you're a current or former employee at CDC or FDA in a food safety role, I'm interested in speaking with you for a story for @wired.com. You can reach me securely at emullin.06 on Signal.

Definitely one of the better articles, someone should compare and contrast CDC budgets (ELC allocation if they can find it) proposed by presidents and what gets approved by Congress. IIRC, Trump proposed to cut the CDC in half but Congress eventually settled with a relatively slight decrease.

A lot of attention has gone to Kennedy making cyclosporiasis optional for FoodNet reporting. But cuts to state and local health departments -- and the loss of CDC expertise -- are a much bigger deal. My latest: www.theguardian.com/society/2026...

I need to find out how to consult for these articles. No mention of the 2020 outbreak that likely pointed to agricultural water (I doubt we ever find the actual source). And a misunderstanding that Foodnet's whole deal is source attribution not early detection of cases.

CDC announces the end of the outbreak; FDA continues its investigation.
