Profile Summary

I completed masters in Photonics from Cochin University of Science and Technology and currently working as a PhD student at University of St. Andrews which commenced on September 2009.

I am working on Microfluidic based optical micromanipulation systems for enhanced spectroscopy.

SPIE scholarships I have received in 2011 and 2009 was among various awards I received during my academic pursuit. (Press release: http://www.scribd.com/doc/61117771)

Other than my research interest I keep a keen interest in optics education. I am actively involved in design and execution of various optics outreach activities, including design of an optics kit for school students.
