Rachael Dempsey - Host

Community Manager at Posit, PBC

I love connecting people across the data science community to share what they're accomplishing with data and help others do the same through community discussions, industry meetups, and more.

Libby Heeren - Co-host

Hangout Community Manager & Posit Academy Mentor

I'm a data science educator and community builder who wants to help you cultivate a community of practice for yourself. I talk a lot about the benefits of making genuine human connections, the power of vulnerability, and why we all benefit when we show up as our whole selves. I'm also the host of the Data Humans podcast where my motto is: data science is not one thing.
