For the first time we are hosting two courses simultaneously this year. Our #new course Advanced Confounding Adjustment began yesterday! 🎉 Joy Shi and Barbra Dickerman welcomed 130 participants from across the globe in leading the first couple lectures and hands-on sessions.

So excited for the second week of CAUSALab summer courses! Looking forward to meeting participants of our Target Trial Emulation course today 🎉

Had a great time serving as a Teaching Fellow for the ACA course. Big thanks to the instructors Barbra Dickerman , Joy Shi, and Miguel Hernán , my co-fellows Sophia Rein , Naiyu Chen , and Sanjana Bhaskar , as well as to all participants for this insightful week!

Today, Curriculum Fellows Sarah Robertson & Lawson led wonderful hands-on sessions 👏 For CICI, Sarah covered composite #datasets & balance assessment. For TTE, Lawson delved into estimating effects in target trials vs emulated target trials. Learn more about our fellows below ⬇️

Meet our terrific #TTE curriculum fellow, Emma McGee! She is now in her third year working on the courses, and we can't imagine them without her. Emma recently graduated from Harvard Epidemiology and joined CAUSALab as a postdoc 👏 Learn more about Emma below ⬇️ #2024CAUSALabcourses
