Is there a way (via client or API) to list all the channels a given user is currently in? I do not see a way to view this information on their profile page in the desktop Slack client.
Alternatively, is there a way to list a user's channel join log/history?

To get the list of channels a user is member of is not something you can do with the standard Slack client, but its rather easy to achieve with the web API. Here is my answer on the same question from stackoverflow: Get list of channels a user is a member of.
