Dr. Khan earned her Ph.D. in Physics at Kansas State University studying the growth and characterization of Group III-V Nitrides by metal organic chemical vapor deposition.

She joined GGC in fall 2010. Her teaching is focused on accomplishing two main objectives: to induce the ability in students to think independently, and to use practical applications to facilitate an understanding of fundamental concepts and problem solving. She has a strong desire to make a positive difference in her students learning through her teaching and innovative research so that they will become productive and creative professionals, in their academic career and research endeavors.

Her research interests are growth of semiconductors, device physics and nano lithography of polymers. She has expertise in growth of thin films of semiconductors by metal organic chemical vapor deposition, and characterization techniques such as x-ray diffraction, atomic force microscope, electroluminescence, and Hall Effect measurements.
