[Answer]-Change the model that modelForm's save, is saving

Assuming that fields in the model form for MyUser are exactly similar to fields of your special user types, you can do something like this

def save(self, *args, **kwargs):
        if self.fields['role'] == 'researcher'
             return ResearchUser.objects.get_or_create( **self.fields)
        ....
        else: # if none of above
             super(MyUserForm, self).save(*args, **kwargs)

Note: you may want to use something better than .get_or_create(), which will do look up for existing objects on all fields provided. But it may not find one and try to create new.

Refer the docs for exact behavior.
