R-Ladies Philly

About Us

We are the Philadelphia chapter of R-Ladies Global, a world-wide organization that promotes gender diversity in the R community and in data science more broadly. While our group name does have ‘R’ and ‘Ladies’ in the title, we welcome all individuals who share our values and follow our code of conduct and who have an interest in data science, regardless of proficiency with R.

Since our first meetup in January 2018, R-Ladies Philly has grown to a highly active, diverse and community-driven group, with:

  • Over 1,500 members
  • Informal monthly meetups that are skills-focused, free, and focused on interdisciplinary statistical and coding methods
  • A quarterly networking happy hour series
  • Real-world data analytic projects that promote group work and help local nonprofits
  • Collaborative engagements with other local data science groups
  • A mentor/speaker directory

We are always looking for more ways to grow and for new data approaches to try! Connect with us via the R-Ladies Philly Slack, Email philly@rladies.org or better yet, come to one of our Meetup events!

Chun is a bioinformatics scientist at the Children’s Hospital of Philadelphia, where she explores the influence of the molecular regulatory architecture on the genetic susceptibility for childhood diseases by analyzing genomics data. She completed her PhD in Biology at the University of Virginia, studying a family of parasitic plants that infect crops in Africa. She uses R extensively for statistical analysis and data visualization in her research. Chun joined R Ladies Philly to learn data science and socialize with local R users.

Alice Walsh, PhD

Alice is a computational biologist who works in pharmaceutical drug development and has lived in the Philadelphia area for the last ten years. She uses R to transform biomarker data from patients into useful insights that can help doctors make better decisions. Alice was inspired to start an R-Ladies chapter in Philadelphia after seeing a video of another R-Ladies meetup online.
