The OHDSI community will vote for their favorite and we will crown a winner! Do you sing or play a musical instrument? Do you dance? Can you do magic or comedy? Do you have some other unique skill that you can demonstrate in 6 minutes or less? We want to see it! If you are interested in participating, please fill out this form.
