Congratulations to Mark O'Masta who received his Ph.D. in Materials Science. Mark's dissertation titled "Mechanisms of Dynamic Deformation and Failure in Ultra-High Molecular Weight Polyethylene Fiber-Polymer Matrix Composites" has elucidated the mechanisms of ballistic penetration in this polymer composite. Mark will be with the group over the summer while he finishes several papers and considers several opportunities well suited to his learned skill-set and inquisitive nature.
