Autumn Bullard

Autumn Bullard, Ph.D.

Associate
Biomedical Engineering
Philadelphia

Dr. Bullard’s background is in biomedical engineering with a specialization in neural engineering and neural prostheses. She has used her skillset in signal processing, implementing machine learning algorithms, designing and fabricating printed circuit boards, and embedded systems engineering to develop implantable devices for brain machine interfaces. Dr. Bullard has experience programming in MATLAB, C++, and Labview as well as experience with SOLIDWORKS, Eagle CAD, FIJI/ImageJ, and NEURON software. Furthermore, she has extensive experience with non-human primate experimental design, behavioral training, and sterile surgical techniques.

Prior to joining Exponent, Dr. Bullard obtained her doctorate from the University of Michigan where she was a research assistant in the Cortical Neural Prosthetics Lab. Her doctoral work focused on designing electronics for an implantable neural recording system to facilitate brain machine interfaces for applications in functional electrical stimulation and upper-limb prosthesis. This work involved in vivo testing, investigation of power reduction techniques, and the characterization of intracranial device-related complications and safety concerns. Dr. Bullard has been involved in both human and non-human primate studies where she gained experience processing intracortical and electromyography (EMG) signals, analyzing histology, and writing systematic reviews and an Investigational Device Exemption (IDE) for FDA submission.
