Tim Ryan

Having studied Biomedical Science at the University of Warwick Tim decided he didn’t fancy looking down test tubes for the rest of his life. Having enjoyed working with data in projects over the course of his studies he wanted to get more involved. With this in mind he looked into career paths in data and found The Data School.

During the application process he fell in love with tableau and the fine balance it achieved between the ingenuity of the software and complex analysis that it afforded to its users. In his spare time Tim can be found playing video games, listening to music or watching sports.
