Metropolitan Isidore (Nikolsky) was instrumental in the growth of Orthodox Christianity in North America as the hierarch in charge of all parishes of the Russian Orthodox Church during his time as Metropolitan of Novgorod and St. Petersburg. Yet - we know almost nothing about him in the English speaking world. That needs to change, and a good thesis covering the life and works of Metropolitan Isidore could go a long way in filling this gap. Please contact me if you would be interested in making this your thesis topic. You can learn just a little bit at the orthowiki entry for Metroplitan Isidore.
