Folina is currently very interested in 19th Century philosophy of mathematics,
including the work of Hamilton, De Morgan, and Bolzano. She continues to be interested
also in 20th Century philosophy of mathematics, including Poincaré and Weyl. She is also
interested in the topic of justification in mathematics quite generally; in particular,
the role of visual evidence and other less "rigorous" forms of justification,
and their relation to mathematical proofs. 

Folina has taught at Macalester since 1989. 

EDUCATION: B.A., Williams College; M. Phil., Ph.D., St. Andrew’s University,
