Stefano Meschiari, Ph.D.

Data Science Technical Lead at Duo Security


Hello! I am a Data Science Technical Leader at Duo Security (Cisco Systems). I am passionate about bringing machine learning to practical applications that are genuinely useful and remove friction from people's lives.

I am also a maker of open-source scientific tools and games (in various states of un-maintenance), an enthusiast for open data and citizen science, and all-around tech geek.

In my past life as an astrophysicist, I discovered new planets and worked on understanding how Tatooine-like planets (planets orbiting binary stars) formed.
