Johanna Goodman, Ph.D.
Associate
Polymer Science & Materials Chemistry
  • Natick

Dr. Goodman’s core discipline is chemical engineering with a focus in electrochemistry. She has a deep understanding of material properties, electrochemical degradation, and morphological characterization with a focus in energy storage. She has extensive experience characterizing electrodes for a wide variety of primary and secondary battery cells with specific focus on lithium systems. She is also knowledgeable in traditional organic and novel ionic liquid electrolytes as well as electrode preparation, cell design and assembly, and evaluation protocols. This broad engineering background enables her to work in a variety of markets including consumer electronics, medical devices, transportation and industrial systems.

Dr. Goodman has experience conducting electrochemical analysis on individual electrodes as well as full cells and systems including potentio/galvano-static analysis, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). She also has experience with post-mortem analysis, specifically dendrite growth in lithium batteries. Analytical techniques include scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX/EDS) and secondary ion mass spectroscopy (SIMS). She also has experience using X-ray diffraction (XRD) for the analysis of battery active materials.

Prior to joining Exponent, she worked as a Postdoctoral Fellow at Georgia Institute of Technology on sulfuryl chloride primary cells as a power source and trigger mechanism for vanishing sensor packages. She also worked on a system-level microgrid model to optimize the design and dispatch of such a system. Before graduate school, she prepared electrodes and membranes for direct methanol fuel cells.
