Dr. Dixit specializes in solid mechanics, material characterization, plasticity, and laboratory testing. She also has experience in computational modeling, including finite element analysis (FEA) and vehicle dynamics simulations.

Prior to joining Exponent, Dr. Dixit was a graduate research assistant at the Hopkins Extreme Materials Institute (HEMI) at the Johns Hopkins University. Her doctoral research focused on understanding the dynamic deformation behavior of light-weight metal alloys. Her research included quasi-static and dynamic (high-strain-rate and impact) testing of constitutive properties and microstructural characterization. Through this work, she developed a strong background in understanding the structure property relationship of magnesium and magnesium alloys. Through rigorous coursework and collaborations, Dr. Dixit has developed a deep understanding of micro-scale deformation mechanisms while applying techniques such as optical microscopy and electron microscopy via SEM and TEM. She gained hands-on experience with laser interferometry, transient digitizers, gas guns, and split Hopkinson bars during her research. While at Johns Hopkins, Dr. Dixit also simulated her high-strain-rate tests using FEA and developed constitutive models to understand material behavior at high deformation rates. She also gained experience in molecular dynamics (MD) simulations as a visiting scholar at the National University of Singapore. Dr. Dixit served as a teaching assistant for the graduate-level course ‘Applied Mathematics for Engineers’ and the undergraduate course ‘Materials Selection’ at Johns Hopkins. 

Dr. Dixit received a Master of Science degree in Mechanical Engineering from the Ohio State University. Her research focused on vehicle dynamics using computational tools to analyze factors affecting vehicle handling and stability. Dr. Dixit’s past experiences include projects in design optimization, piezoelectric smart materials, and a variety of manufacturing techniques.
