Biography

I studied Chemical Engineering and completed my thesis under the supervision of Prof. Jalil Razavi at Sharif University of Technology in 2008. As part of my degree I undertook a placement in industry at the HSE section of Pars Oil Co. where I learned about risk assessment and hazard and operability studies in chemical plants. I came to the UK for Master's studies in Environmental and Energy Engineering, completed a research project on fabrication of colloidal clusters under supervision of Dr Jonathan Howse and graduated with a Distinction at the University of Sheffield in 2009.

Research

Locomotion at the micro-scale is attracting growing interest among scientists and this attention is driven by both a demand for understanding the mechanism of the motion biological organisms and a desire to fabricate devices capable of performing useful tasks such as cargo delivery and stirring inside fluidic environments restricted by a low Reynolds number. To perform these complicated tasks, an efficient mechanism is required for controlling the trajectory of microparticles. My research concerns investigation of navigation strategies for steering propulsive and non-propulsive polymeric microspheres on the surface and in the bulk. To achieve this I have examined different methods such as modifying the surface chemistry of the substrate which particles roll upon, achieving a statistical accumulation of particles by exploiting the trajectories of a collection of similar propulsive particles and controlling the orientation of the particles using external stimuli such as a magnetic field.
