Waterpark: Transforming Healthcare with Distributed Actors - Bryan Hunter - NDC Oslo 2025

[00:00.000 --> 00:16.400]  Hello, hello, and welcome to "Waterpark - Transforming Health Care with Distributed Actors".
[00:16.400 --> 00:17.400]  My name is Brian Hunter.
[00:17.400 --> 00:22.160]  It is awesome to be back in Oslo, and it's a joy to be here today to share some of my
[00:22.160 --> 00:24.520]  team's research.
[00:24.520 --> 00:31.240]  This research led to a product with an unusual architecture that's out there doing good
[00:31.240 --> 00:36.000]  in the world, and so it's going to be fun to share this with you all.

[00:36.000 --> 00:40.360] All right, so I'm an Enterprise Fellow at HCA Health Care.
