 Kevin Markham is the founder of [Data School](http://www.dataschool.io/) and the former lead instructor for [General Assembly's Data Science course](https://github.com/justmarkham/DAT8) in Washington, DC. He is passionate about teaching data science to people who are new to the field, regardless of their educational and professional backgrounds, and he enjoys teaching both online and in the classroom. Kevin's professional focus is supervised machine learning, which led him to create the popular [scikit-learn video series](https://github.com/justmarkham/scikit-learn-videos) for Kaggle. He has a degree in Computer Engineering from Vanderbilt University.
