Dr. Cummings started her career as a National Science Foundation post-doctoral fellow, developing models of acoustic wave propagation in the vocal tract based on the finite difference time domain method. She continued on the faculty at Georgia Tech, teaching courses in applications of digital signal processing, statistics and random signals and noise, and linear systems. Her research interests included digital speech processing, especially modeling, synthesizing and recognizing distressed or emotional speech, as well as general digital signal processing. She was involved in collaborative research in the effects of alcohol on speech. More recently, Dr. Cummings developed the training course and materials, along with the technical manual, for a 40G optical transport system. In addition, she was the founder and President of the Board of Trustees of a 501(c)(3) public charity, overseeing its growth to a budget of $55,000 within the first two years. She has served as President and Ex-officio of the Board of Trustees of another 501(c)(3) and is actively involved in STEM (Science, Technology, Engineering and Mathematics) high school education in Cobb County, Georgia. As the co-owner of Compass Technology Group, LLC, she is actively engaged in research in materials, antennas, and signal processing and has been the Principal Investigator for several successful Phase I and II SBIRs.
