Stefano Meschiari, Ph.D.

Data Scientist


Hello! I am a Data Scientist passionate about creating practical data science solutions that are useful, transparent, and scalable. Most recently, I was a Technical Lead at Duo Security (Cisco), where I led the development of Duo Trust Monitor.

I am also a maker of open-source scientific tools and games (in various states of un-maintenance), an advocate for open data, reproducible research, and citizen science, and avid learner of all things technology. I love creating and sharing knowledge.

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