Research Interests

The behavior of liquids and their interfaces underlies many important phenomena across the biological and physical sciences. I use molecular simulations and statistical mechanics to elicit the microscopic details of interfacial systems, with an emphasis on perhaps the most important of all liquids: water and its salt solutions. 

Recent research has focused on improving simulations methods to give a better description of ions adsorbed to charged interfaces [1], which is important for tackling complex problems such as ice nucleation [2]. I also have a keen interest in understanding dielectric response in water [3,4] and its implications for aqueous ion solvation [5].

Possible PhD projects involve improving simulation methodology to understand the structure and dynamics of charged interfaces in solution; using molecular simulations to understand how polar crystals grow; or pursuing theoretical approaches to improve our understanding of complex fluids.
