My parents were able to put food on the table because of foodstamps. The fact that 42 million people are about to lose SNAP benefits breaks my heart.

Causal Machine Learning Methods and Use of Cross‐Fitting in Settings With High‐Dimensional Confounding
Observational epidemiological studies commonly seek to estimate the causal effect of an exposure on an outcome. Adjustment for potential confounding bias in modern studies is challenging due to the p...

NEW PAPER! (in press in EPIDEMIOLOGY)
Have you wondered:
- How to specify a target trial: as an ideal trial or something else?
- What biases do target trial emulations and actual RCTs share?
- How does it all relate to potential outcomes?

We have a new vaccine manufacturing facility in Quebec intended originally to make Novavax that is going unused.
