PhD Querry

I am currently a M.Tech (Mechatronics, Department of Mechanical Engineering) student in IIT Patna. I have strong interests in Applied Mechanics with special focus on Dielectric Elastomer Actuators. I am expecting to graduate by May 2016. Currently i am working on dielectric elastomer actuators and want to continue this in my PhD also. Are there any opportunities for PhD positions available at Harvard Solid Mechanics? What are the essentials needed for the above.

Thanks
