Over at Scienta et Sapientia several papers written by my classmates for our class on the Greek Father have been (or soon will be) posted. If you enjoy patristics, especially Greek patristics, you should see if anything seems interesting. Thus far the list includes a paper on John of Damascus and iconoclasm (here), the image of Irenaeus  in recent scholarship (here), Gregory Nazianzen’s understanding of Trinitarian relationship (here), and my aforementioned introduction to Athanasius’ Letters to Serapion on the Holy Spirit (here). There should be another half-dozen or so coming down the pipe.
 Yes, Irenaeus was not technically a “Greek Father” but we studied him because along with Origen he was highly influential on their theology.
