Dr. Grocke is a chemical engineer by training, specializing in electrochemistry and materials engineering. He has extensive research experience in the synthesis, characterization, and functional control of semiconducting and energy storage materials. He is also well versed in battery assembly and testing, as well as the design and fabrication of custom experimental apparatuses. At Exponent, Garrett uses these skills to provide assistance to clients in design evaluation, qualification, and failure analysis of products for a wide variety of applications including consumer and commercial electronics, medical devices, and electric vehicles.

Dr. Grocke has experience in numerous analytical techniques for electronic and polymeric materials characterization including electrochemical impedance spectroscopy (EIS), cyclic and linear sweep voltammetry (CV and LSV), UV-visible spectroscopy (UV-Vis), thermogravimetric analysis (TGA), microscopy, and X-ray scattering techniques.

Prior to joining Exponent, Dr. Grocke's graduate research focused on the synthesis and characterization of novel organic semiconductors and battery active materials with mixed ionic-electronic conduction, with applications in sensors, thermoelectrics, and renewable energy storage systems. Additionally, his research at Argonne National Laboratory focused on the synthesis of high-anisotropy functional nanomaterials, with applications in catalysts, energy storage, and magnetic materials.
