*Nomen mihi
*in takes the ablative, not the dative
*quam would be better than hanc
*intelligere, not cogitare
*tamen can't be the first word in a sentence or clause
*geekorum linguae rex would be better
*the last clause barely makes any sense. "Therefore it is not great with this device/artifice/trickery?" Are you perhaps going for dolore, sadness/pain?
I suppose you could make Medieval Studies into studiis Medievalibus.
