In the first hour, I will describe the standard trisection of CP^2 and how to put complex curves in CP^2 into bridge position with respect to this trisection.  Time permitting, I will also present trisections of projective surfaces obtained as a branched covers over these curves.  In the second hour, I will describe how to compute the homology and intersection form from a trisection diagram.
