Annalisa Crannell received her PhD from Brown University, writing her dissertation in the area of non-linear partial differential equations. For many years after that, she published in the area of discrete topological dynamical systems, with particular interest in quasi-continuous functions.
But her current research is much more accessible and visual. Together with students and with research colleagues, she asks questions about the applications of projective geometry to perspective art: specifically, how the heck do we project our three-dimensional world onto a two-dimensional canvas?
Crannell teaches classes ranging from Calculus to Projective Geometry to Analysis, and she also enjoys including students in independent studies and research.
