If you haven't already transported yourself away from X, here's my latest paper on transportability: onlinelibrary.wiley.com/doi/… Featuring: adaptive treatment strategies, kidney-pancreas transplant, @docvock, @SRTRNews, and more!

Transportability of causal inference under random dynamic treatment regimes for kidney–pancreas...

A difficult decision for patients in need of kidney–pancreas transplant is whether to seek a living kidney donor or wait to receive both organs from one deceased donor. The framework of dynamic...

Looking at correlated chemical mixtures? Lots of proposed extensions and mods to WQS, but this new method tackles data splitting. Dissertation from Dr. Smarty McSmarty Pants (AKA @gracelyden) 🥳! Great to work with her and @docvock. journals.sagepub.com/doi/10.…
