Collaborative Support

Across a broad spectrum of both research and real-world applications of nanotechnology, the leadership and staff of the Singh Center promote the emergence of new ideas and innovations through their work.

Mark G.

Mark G. Allen

Scientific Director, Singh Center for Nanotechnology,
Alfred Fitler Moore Professor
Electrical and Systems Engineering,
Mechanical Engineering and Applied Mechanics

Dr. Allen is the inaugural Scientific Director of the Krishna P. Singh Center for Nanotechnology. Combining insights from the worlds of electrical engineering, mechanical engineering, chemistry and materials science, Allen is a pioneer in the field of micro-electromechanical systems, or MEMS, and nanofabrication technology.

Mark’s research allows the creation of structures, sensors and actuators that exploit the unique potential of the small scale. For example, such miniscule devices can sit at the intersection of the biological and the digital, sensing the physical and electrical signals found in the heart and in the brain and transmitting them to computers for processing. Mark has published approximately 120 journal articles and holds approximately 40 patents.
