Research Interests

Protein phase separation and clustering

Although proteins are highly anisotropic molecules both in terms of their shape and their interactions, the role of this anisotropy is not fully understood. In order to provide insight, a toy model of globular proteins coupled with Monte Carlo simulations is used to determine the effect of the competition of isotropic and directional interactions both in phase separation and in clustering.

Hydrodynamic properties of dilute particle solutions

The efficiency of a code, ZENO, to compute several quantities including the intrinsic viscosity and hydrodynamic radius is being improved. Additionally, the code is used to explore the role of shape on hydrodynamic properties for a class of cube-like particles. Computations are directly compared with experimental results and are found to be accurate within experimental uncertainty.
