Aamer Mahmood
Senior Process Scientist – Nanofabrication and Characterization
Phone: 494-6697

Aamer is responsible for developing semiconductor and MEMS fabrication processes. He holds additional responsibility of the Electrical Characterization Laboratory. His primary responsibilities are to develop microfabrication processes and to provide microfabrication and characterization services to academic and industrial users.

Aamer has a B.E., an M.S. and a Ph.D. degree  in Electrical Engineering and has more than 15 years of experience in academia and industry. His graduate and professional experience spans the areas of electromagnetic scattering, high gain antenna characterization, development of uncooled infrared sensors, development of a device-level vacuum-packaging scheme for microbolometers and the development of large deflection MEMS actuators. He joined Purdue as a Post Doctoral Researcher in September 2006 and since August 2008 has been working as a Microfab Research Engineer.


Dmitri Zakharov
Staff Scientist/ Electron Microscopy
