Honored to give a workshop and keynote at #NordicEpi #NorPEN 2026 in Tromsø. The workshop focused on target trial emulation in pregnancy research; the keynote on improving causal inference by design for complex public health questions.
Excited to contribute to a workshop on target trial emulation in pregnancy research with @HanChiu_ . We covered sequential trials, immortal time bias, point/sustained strategies, artificial censoring, and IPW. #TargetTrialEmulation #CausalInference #Pregnancy #NordicEPI #NorPEN

We developed an estimator to improve the efficiency of RCTs by integrating extetnal controls, which is consistent even if the transportability assumption does NOT hold. Pharmas can finally use the external control worry-free!

New research published @AnnalsofIM challenges past scholarship on #metformin.
CAUSALab research collaborator @HanChiu_ identified no increased risk for childbirth with major birth defects when compared w/ women who discontinued the drug.

With #TargetTrial emulation becoming increasingly popular, it's important to understand what it can and cannot do.
In this new podcast, I discuss how target trial emulation can 1) improve causal inference from observational data, and 2) extend inferences from randomized trials.

A blanket ban on the use of causal language in observational studies has long precluded nuanced discussion about which associations, if any, are truly causal
Fantastic work by Issa Dahabreh (@CAUSALab @SmithBIDMC) and @KBibbinsDomingo changes this
