Are you available for workshops?

Yes, I have done a number of workshops, on a paid basis. I can come to your institution and give a few days of instruction.

Usually the first day starts with a 1-hour overview of oTree for a general audience. Then we begin with hands-on instructions on how to program oTree experiments, as well as things like deploying to Mechanical Turk, using bots, using the admin interface, setting up a server, etc.

No prior experience with oTree is necessary, although participants should have completed a basic tutorial in Python programming.
