Thanks for your message. Great to see that there are plans to start a new department. There are a lot of factors to consider but I think one of the most important would be around
a) Generating interest and support from leadership and from faculty
b) Having a clear set of goals for the department in terms of what you might teach; how and where this will be integrated; and how it will form part of assessment.
We discuss this in relation to social and behavioural science in our Webinar (May 2018) so you may want to have a look at that.
Always happy to discuss more directly as well if you want to contact me - [email protected]
