Dr. Matthews grew up in Paris, Texas, and earned her B.S. and Ph.D. degrees from Baylor University. From 1998-2000 she was employed as an engineer at Raytheon Aircraft Integrations Systems, where her main project was vibroacoustics analysis for NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA). In 2000 she returned to Baylor as a lecturer in the Physics Department and Baylor Interdisciplinary Core and Senior Research Scientist with CASPER, and is now a Professor of Physics and Associate Director of CASPER.

Research Interests

Dr. Matthews is engaged in both theoretical and experimental research in dusty plasmas. Dusty plasmas, which consist of micron-sized solid grains immersed in ionized gas, are found in many astrophysical environments. Her research interests include the early stages of planet formation involving the charging and coagulation of dust, planetary ring dynamics, and the self-organization of laboratory dusty plasmas into dust crystals, Coulomb balls, and dust strings. Another area of interest is hypervelocity impact studies, in relation to designing shielding material and dust detectors for space missions.
