Nanoscale science and engineering now impact every aspect of technological innovation. As a result, the Hastings' Research Group takes an integrated research approach that requires understanding of a technology from its fundmental physics to its day-to-day application. With the help of many collaborators, this approach allows the group to direct its efforts and expertise toward the most critical point in the research chain. Current areas of emphasis include new tools and methods for nanofabrication and nanomanufacturing, novel devices for electronic and photonic bio-chemical sensing, and integrated photonics for communications.
