The main idea of the mathematics unit is to develop research that draws inspiration from and connects to different mathematical disciplines and also to encourage collaborations with scientists in areas such as biology, physics, social sciences, earth sciences, computer science, and many others, thus making it an integral part of the scientific ecosystem within ICTS.

The group pursues a wide range of **mathematical, statistical and computational** research themes. In particular, current research includes dynamical systems, probability, nonlinear partial differential equations, geometry and mathematical physics.

**Opportunities:**

The group envisions a significant and sustained growth in many areas and at all levels. Specific research areas that we would like to grow include, but are not limited to, probability and stochastic analysis, geometry and topology, mathematical physics, dynamical systems and differential equations, scientific computing, and discrete mathematics. ICTS would also like to develop a theoretical computer science group as part of this unit.
