Mathematical Interests 

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 colleauges, 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?

Teaching Interests 

Crannell teaches classes ranging from Calculus to Projective Geometry to Analysis, and she also enjoys including students in independent studies and research. 

She has two books on the mathematics of perspective art:


Her work on Writing within the Mathematics Curriculum includes numersous talks, articles, and the MAA book (coauthored with Elyn Rykken, Tommy Ratliff, and Gavin LaRose): Writing Projects for Mathematics Courses: Crushed Clowns, Cars, and Coffee to Go.

She is exceedingly fond of using Inquiry Based Learning and the Modified Moore Method in her teaching.  Some of the worksheets she uses in her class appear in these Course Materials pages.

Professional Service

Crannell is active in several national mathematical societies, including the 

She has served on the Board of Governors of the MAA and on the Executive Council of the AWM.  She has long been a mentor/consultant for early-career mathematicians through the MAA's Project NExT program.

Two of her most relevant publications for professional service include
