Rachelle C. DeCoste

Associate Professor of Mathematics

Ph.D., M.S., University of North Carolina, Chapel Hill
B.A., Connecticut College

Research Interests

Geometry of two-step nilpotent manifolds, particularly distribution of closed geodesics
Lie symmetries acting on differential equations

Other Interests

Encouraging students, particularly those who are underrepresented in the field, to study mathematics. I enjoy exposing students to the beauty of mathematics, both inside and outside of the classroom.

I founded and direct the Career Mentoring Workshop (CaMeW) for women finishing their PhDs.  Through the workshop, we have mentored over 60 women at this critical transition point in their careers.  I continue to seek funding to support the workshop in future summers.
