Saleh Chebaane

what kind of proposal do you suggest doctor ?

Roger Stambaugh

Coupling the optics of the endoscope with a laser would be an interesting project. The laser would have to be well targeted so it would not damage adjacent tissue. This laser would have applications in both medicine and dentistry. I did some preliminary work on this with Candela, a laser company near Boston.

Gaurav Kumar Yogesh

currently, I am working with nanosecond pulse laser for material processing. Including the synthesis of Fluorescent nanoparticles for bioimaging (in a medical application). It is one of the emerging fields.
