call to members profiles, not member activity

Hi,
We are running a BuddyPress/Multi site environment for students and staff, and we are very happy with the BP Social Theme.

Recently I have asked a group af students to put in a unique keyword in one of their profile fields, so that we can link to a search result of that particular keyword (=group of people).

However, for us it would be more user friendly if the resulting list of users was made up of links to each user's profile: http://mediajungle.dk/members/irnielsen/profile/

instead of links to each members personal activity stream: http://mediajungle.dk/members/irnielsen/

Could you give me a hint as to where to customize this?

Thanks!
