Professional Experience

After completing her Ph.D., Angela began a post-doctoral position at LLNL. She has 15+ years of experience in bioengineering research and 12+ years of experience in MEMS research and fabrication. This includes design, fabrication, testing, and packaging of MEMS devices for biological and mechanical sensing applications. She has extensive experience in integrating polymers into microfabrication processes and MEMS devices. This includes material biocompatibility and material lifetime (electrical, chemical, and mechanical) studies, new material development, and MEMS microfabrication process development for both in vitro and in vivo biological applications. Current research involves the development of new, longer-lasting biocompatible materials and new fabrication processes for implantable microelectrode arrays for neural prosthetics (e.g., auditory and visual prostheses).
