Unfortunately, it doesn't look like New York University offers mortuary sciences.
American Academy McAllister Institute of Funeral Service sounds like it could be a great option for you. CUNY LaGuardia Community College also offers a joint program with the McAllister Institute.
You may want to look over this list of schools In New York that potentially have mortuary sciences programs.
Best of luck!
