Open Office Hour

I will ocassionally be holding group open office hours (fully ONLINE) for *anyone*. Feel free to sign up to connect, chat, or ask any questions.

When I was a student, I was clueless sometimes (if not most of the time) and I had no idea how to get help. I hope that, via this modest effort, I can share some experience with you, as well as address some questions you may have, using my experience working in both industry and academia and applied and research projects, as well as experience in studying abroad in the US. I encourage to converse in English.

This effort is inspired by ML Collective
