Have her run an adventure. Writers make great DMs.
I don't know if Kimberly would be interested in DMing; right now she's just getting used to the 4e rules system (and playing a 4e PHB Warlord without the electronic charbuilder is jumping in at the deep end, IMO). Depending on her research plans & desires it might be a good idea for her to try her hand at DMing some time though, at least a one-shot, I agree.
