Year ✌️ en route! 🏥🩺

Internship was certainly one of the most rewarding years of my life. New friends, colleagues, responsibilities, and a heightened appreciation for SPF 500! ☀️🧴

Bring on the “new year”! Happy Fourth of July! 🇺🇸🎇🎆

Congratulations to one of my amazing partners at the Mayo Clinic, Dr. @samarthrawal, on his latest AI clinical reasoning tool!

[Sam Rawal, MD @samarthrawal]

Although not planned out in advance like this, this is the second in a set of tools I have built, that represent some of my thoughts on how clinical AI can be useful, from a practical, physician-first standpoint.

Largely due to my experiences as a resident physician, I have been focusing on developing tools that use AI to *augment* clinician reasoning, rather than *replace* it.

Conceptualizing the clinical reasoning environment (whether it's within a EMR or some other software) in a way that facilitates both clinician thinking, as well as AI input, is key to this.
