American mathematician and book author
From Wikipedia, the free encyclopedia
Sarah-marie belcastro[1] (born 1970), stylized sarah-marie belcastro, is an American mathematician and book author. She is an instructor at the Art of Problem Solving Online School[2] and is the director of MathILy,[3] a residential math summer program hosted at Bryn Mawr College. Although her doctoral research was in algebraic geometry, she has also worked extensively in topological graph theory.[4] She is known for and has written extensively about mathematical knitting, and has co-edited three books on fiber mathematics.[5] She exclusively uses the form "sarah-marie belcastro".[6][1]
Biography
Belcastro was born in San Diego, California, in 1970, and grew up mostly in Andover, Massachusetts, and in Dubuque, Iowa.[7] She earned a B.S. (1991) in Mathematics and Astronomy from Haverford College, an M.S. (1993) from The University of Michigan, Ann Arbor, and a Ph.D. (1997) there for a thesis on “Picard Lattices of Families of K3 Surfaces” done with Igor Dolgachev.[8]
Since 2012, she has also been an instructor at the Art of Problem Solving Online School.[2] Since 2013, she has been the director of Bryn Mawr College's residential summer program MathILy (serious Mathematics Infused with Levity).[3] She is also a guest faculty member at Sarah Lawrence College.
She was Associate Editor for The College Mathematics Journal (2003–2019). She has also lectured frequently at the University of Massachusetts, Amherst since 2012.[9][10]
