Joan Hutchinson was an employee for whom from 1990 to 2007?
Joan Hutchinson Joan Prince Hutchinson ( born 1945 ) is an American mathematician and Professor Emerita of Mathematics from Macalester College . Education . Joan Hutchinson was born in Philadelphia , Pennsylvania ; her father was a demographer and university professor , and her mother a mathematics teacher at the Baldwin School , which Joan also attended . She studied at Smith College in Northampton , Massachusetts , graduating in 1967 summa cum laude with an honors paper directed by Prof . Alice Dickinson . After graduation she worked as a computer programmer at the Woods Hole Oceanographic Institute and at the Harvard University Computing Center then studied mathematics ( and English change ringing on tower bells ) at the University of Warwick in Coventry England . Returning to the United States , Hutchinson did graduate work at the University of Pennsylvania earning a Ph.D . in mathematics in 1973 under the supervision of Herbert S . Wilf . Career . She was a John Wesley Young research instructor at Dartmouth College , 1973–1975 . She and her husband , fellow mathematician Stan Wagon , taught at Smith College , 1975–1990 , and at Macalester College , 1990–2007 . At both colleges they shared a full-time position in mathematics . She spent sabbaticals , taught , and held visiting positions at Tufts University , Carleton College , University of Colorado Boulder , University of Washington , University of Michigan , Mathematical Sciences Research Institute in Berkeley , California , and University of Colorado Denver . She has served on committees of the American Mathematical Society , the Mathematical Association of America ( MAA ) , SIAM Special Interest Group on Discrete Math ( SIAM-DM ) , and the Association for Women in Mathematics , involved with the latter organization since a graduate student during its founding days in 1971 . Mentoring women students and younger colleagues has been an important concern of her professional life . She served as the vice-chair of SIAM-DM , 2000–2002 . She was a member of the editorial board of the American Mathematical Monthly , 1986–1996 , and continues on the board of the Journal of Graph Theory since 1993 . Research . Her research has focused on graph theory and discrete mathematics , specializing mainly in topological and chromatic graph theory and on visibility graphs ; for overviews of this work see and . She has published over 75 research and expository papers in graph theory , many with Michael O . Albertson , formerly of Smith College . In one of their most cited works , Albertson and Hutchinson completed work of Gabriel Andrew Dirac related to the Heawood conjecture by proving that , on any surface other than the sphere or Klein bottle , the only graphs meeting Heawoods bound on the chromatic number of surface-embedded graphs are the complete graphs . She has also considered algorithmic aspects in these areas , for example , generalizing the planar separator theorem to surfaces . With S . Wagon she has co-authored papers on algorithmic aspects of the four color theorem . Albertson and Hutchinson also wrote together the textbook Discrete Mathematics with Algorithms . Awards and honors . In 1994 she received the Carl B . Allendoerfer Award of the Mathematical Association of America for the expository article Coloring ordinary maps , maps of empires , and maps of the moon in Mathematics Magazine . The work of this paper was also included in an issue of What’s Happening in the Mathematical Sciences and in the Mathematical Recreations column of Scientific American . In 1998 she was a winner of the MAA North Central Section Teaching Award , and in 1999 she was a winner of the Deborah and Franklin Haimo Awards for Distinguished College or University Teaching of Mathematics . On the occasion of her 60th birthday , she was the honoree at the Graph Theory with Altitude conference at the University of Colorado Denver , organized by her former student Ellen Gethner , professor of computer science .
