I am a professor interested in personal finance and financial independence. My PhD is in a STEM subject, not finance or economics, so I started learning about these topics by reading blogs and introductory books. While I think there’s a lot of sound, straight-forward advice out there that suffices for most people’s financial goals, I wanted to learn more. With my quantitative background, I decided to turn to more technical sources on these subjects and do my own analyses of the data.
