Group

 

My group currently (October 2014) consists of one Ph.D. student and two undergraduate Nanoscience project students. I also have a close collaboration with experimentalists in the laboratory of Prof. John Dutcher, on the subject of bacteria biophysics. Our weekly joint group meetings provide our students with the opportunity to present their latest results to the group in an informal setting.

 

 

 

Research

 

My interests lie in theoretical soft materials physics and biophysics. My current research focuses on two fundamental aspects of polymeric materials: the formation of nanostructures in polymeric materials via self-assembly, and the interplay between these structures and the dynamical evolution of the polymeric material. The study of the structure, dynamics and response of biological assemblies is also a research theme in my group. We use a combination of sophisticated analytical theory and high-performance computation to model the behaviour of these systems.      

Some current areas of interest include:  

1) Kinetics of order-order and order-disorder transitions in block copolymers (movie1 , movie2 )  

2) Development of accurate field theories for polymer and particle dynamics ( movie1 , movie2 )  

3) Modelling bacteria twitching motility on surfaces (movie)

4) Theory for the structure of the bacterial lipid membrane in the presence of antimicrobial peptides
