Breathing new life into old math

Assistant Professor of Applied Mathematics at Brown University, Brendan Keith, is breathing new life into old math. He is trying to update vintage techniques with a method he names proximal Galerkin. Known as finite element methods, assist researchers like Keith to predict how objects might behave in different environments.

In 1990, the Executive Committee of the AWM established the annual Alice T. Schafer Prize for Excellence in Mathematics by an Undergraduate Woman. The prize is named for Alice T. Schafer (1915–2009), one of the founders of AWM and its second president, who contributed greatly to women in mathematics throughout her career.

At Brown, Keith leads a research team using numerical analysis and optimization principles to develop computer algorithms and data-driven mathematical models. He uses these tools, or numerical methods, to tackle challenging engineering problems written as partial differential equations, which are equations used to model physical systems mathematically and whose solutions lie in the infinite-dimensional spaces of functions.

Big Math in Little Rhody

The smallest state in the country has two centers of world-class mathematics. The American Mathematical Society (AMS) and the Institute for Computational and Experimental Research in Mathematics (ICERM) are both located in Providence, RI. The AMS publishes many research journals, and maintains an electronic database called MathSciNet, among many other services. ICERM's mission is to solidify the relationship between mathematics and computation.

Oanh Nguyen receives Salomon Award

Professor Oanh Nguyen was honored with a Salomon Award for her research work regarding the limited distribution for the number of real roots. The goal of her research is to study fundamental problems concerning the distribution of roots of random polynomials and random functions. This is Professor Nguyen's first year as an Assistant Professor in the Division of Applied Mathematics here at Brown.

Professor Kavita Ramanan uses randomness as a powerful tool

Kavita Ramanan, Professor of Applied Mathematics, uses randomness as a powerful tool to make predictions about complex systems. These systems range from statistical physics to communication networks which exist in the world around us. The tool of randomness can even help to determine the spread of infectious diseases. Ramanan states that in our world randomness shows itself as an incomplete understanding of complex systems. However, randomness can enable, even those things which might be computationally impossible, useful predictions about things that are not fully understood.
