Dr. Askounis specializes in the synthesis, characterization and mechanics of polymeric materials with an emphasis on structure-property-performance relationships. She routinely utilizes her expertise by helping clients with material reliability assessments and root cause investigations. In addition, Dr. Askounis assists clients throughout all phases of product development including materials selection, processing and end-use testing.

At Exponent, Dr. Askounis’ project work and research interests include fractography, accelerated aging studies, materials exposure testing, and intellectual property analysis. Dr. Askounis is well versed in free-radical and controlled free-radical polymerization techniques with additional experience in nanoparticle synthesis. She also has extensive experience in small molecule organic synthesis and designing multi-functional monomers for use in macromolecular systems. She is proficient in several techniques to characterize materials, including spectroscopy (FTIR, UV-Vis, NMR), chromatography (GPC), thermal (TGA, DSC), thermomechanical (DMA, TGA), microscopy (OM, SEM), and crystallography (XRD). Dr. Askounis has experience with a variety of polymeric materials, including thermoplastics, elastomers, and thermosets that are often specified for use in the consumer electronics, consumer products, construction, batteries, and mining industries.

Prior to joining Exponent, Dr. Askounis obtained her Ph.D. in Materials Science and Engineering from the University of California, Los Angeles where she led the development, synthesis, and fabrication of new high-performance stimuli-responsive polymer and composite materials. As part of her work, she developed variable stiffness materials stimulated by light, temperature, and solvent, capable of ultra-wide tunable stiffness ranges for use in biomedical applications. She also developed, synthesized, and fabricated new dielectric elastomeric materials and actuators exhibiting both high strain and rapid frequency response for use in robotics applications.
