Dr. Virginie Rollin studied Mechanical and Aerospace Engineering in France at ENSMA (Poitiers), and moved to the U.S. to study for her Ph.D. in Mechanical Engineering at the University of Vermont. During that time, she became an expert in molecular dynamics simulations of nanoindentation in metals.
Upon finishing her Ph.D., she went to the Los Alamos National Laboratory to perform a postdoctoral appointment. For three years, she used molecular dynamics to study different phenomena, such as shocks and compression in metals.
As an Assistant Professor at Embry-Riddle, while continuing her research on nanocrystalline metals, Dr. Rollin also started studying Carbon Nanotube reinforced composites and received funding to build a Carbon Nanotube facility on campus.
During her spare time, Dr. Rollin enjoys flying. She received her private pilot license in April 2011, and has enjoyed flying with the Rio Grande Norte 99s since then. Dr. Rollin recently added an instrument rating as well as high performance and complex endorsements to her license. Dr. Rollin competed in the Air Race Classic in 2016, winning the 3rd place with her teammate Dr. Naiara Petralanda, as Team Bernoulli.
Dr. Rollin is also an experienced scuba diver. She became a certified diver in 2006, and has taken several specialty courses. She has dived at many locations across the U.S. and the rest of the world.
Dr. Rollin also enjoys baking, crocheting, cross-stitching and dancing swing and salsa.
