We're going to the Moon! I'm the Chief Research Scientist at Astrobotic heading their Future Missions and Technology team (https://astrobotic.com/technology). My Ph.D. in Mechanical Engineering at Case Western Reserve University was in the area of biologically inspired robotics with particular interests in mechanical design, soft robotics, dynamical systems, computational neuroscience, and numerical simulation. I have over 25 years of experience with Matlab and C.
