I was a stutterer as a child. I learned English late in a rural middle school. When I came to US for graduate studies, I could not speak a single fluent sentence. During my PhD, I applied for many TA positions and was rejected again and again. But I kept trying to be a little better each time.

Can't believe I get to work with @haidonglu.bsky.social! This is going to be so much fun...

Fascinating talk by @oacarah.bsky.social on selection-augmented causal diagrams in fascinating @societyforepi.bsky.social mid-year meeting symposium on selection bias arranged by @haidonglu.bsky.social!. Blown away by the quality and clarity of thinking 🤯

For this #MEstimatorMonday (24/52), I am going to discuss a new pre-print that @haidonglu.bsky.social and I have that is a sort of intermediate introduction to M-estimators arxiv.org/abs/2506.03347

"Selection bias: where are we now?" Incredibly excited to announce the next Causal Inference Interest Group seminar with @haidonglu.bsky.social will take place on 10th March 2025 at 3pm GMT (11am EDT). Don't miss this one! Register at: turing-uk.zoom.us/meeting/regi... #EpiSky #CausalSky #CIIG

Excited to share that our work on the Four Targets framework has been published in the International Journal of Epidemiology!
