Dr. Munson is a world expert in the characterization of pharmaceutical solids using a variety of analytical techniques, with an emphasis on solid-state spectroscopy.  His group focuses on several areas of research that encompass small and large molecule formulations and drug delivery.  Interests include the characterization of amorphous solid dispersions, including investigating drug-polymer interactions and homogeneity, and how this impacts functional properties such as crystallization; biological systems, including proteins and mRNA LNPs, for predicting stability in lyophilized matrices; and excipients, such as magnesium stearate, and how crystalline form impacts functional properties.
