Under Prof. Robert Shepherd, led team of undergraduate students in initial steps of NASA Innovative Advanced Concepts project to create a squid-like rover that can swim through the oceans of Europa. Also designed, fabricated, and tested soft robotic fin concept to steer rover.http://news.cornell.edu/stories/2015/05/soft-robot-swim-through-europas-oceans
