Olin Professor of Mathematics, Chair of the Department of Mathematics




518 Mathematics Building on Columbia campus
Tuesday 11:30 am - 12:30 pm or by appointment (via email)



Daniela De Silva, professor of mathematics, joined the faculty of Barnard in 2007. Formerly, she was a member of the Mathematical Sciences Research Institute in Berkeley. Professor De Silva has also taught at John Hopkins, MIT, and the University of Naples "Federico II". At Barnard, her teaching duties include Calculus and Analysis.

Professor De Silva's primary research area is partial differential equations. She is particularly interested in the regularity theory for free boundary/phase transition problems.

Professor De Silva is the organizer of the Geometry and Analysis seminar at Columbia University.
