Profile Summary 

The topic of my thesis is to understand the effect of ionic liquids on the phase behavior of self-assembled amphiphiles. Amphiphilic molecules, such as surfactant and phospholipids, self-assemble in aqueous solution and form certain liquid crystalline structures. These structures can be altered by tuning the electrostatics of the system in the presence of charged ionic liquids. In turn, the materials show interesting physical properties which are important for industrial applications. Different x-ray scattering (x-ray diffraction, x-ray reflectivity, grazing incidence x-ray diffraction etc.), Langmuir-Blodgett trough and microscopy techniques are used at in-house and international synchrotron facilities to study the structures and properties of such soft materials and bio-systems.
