Research Interests

I am interested in the elasticity and statistical mechanics of soft and
squishy materials, particularly biological systems that involve an
interplay between elasticity or viscoelasticity, geometry and
microstructural properties. In particular, my research focuses
on the following areas:
• Cell mechanics - how cells and their components react to, generate and transmit forces and how this impacts upon their functions and fate.  
• Microrheology of composite elastic media.
• Effective medium theories of single-component and composite semiflexible networks.
• Liquid crystalline behavior in gels and cells.
• Mechanics of thin elastic sheets and shells.
