Evelyn L. Hu (Chinese: 胡玲) is the Tarr-Coyne Professor of Applied Physics and of Electrical Engineering at Harvard University.

[1] Hu was employed at AT&T's Bell Laboratories from 1975 to 1984, when she joined University of California, Santa Barbara (UCSB) as a full professor, a position she has held since 1984.

[2] She has been a pioneer in the fabrication of nanoscale electronic and photonic devices, and was named Gordon McKay Professor of Applied Physics and Electrical Engineering in Harvard University's School of Engineering and Applied Sciences (SEAS), effective January 1, 2009.

Some of her research ideas led to her co-founding of Cambridge, Massachusetts-based Cambrios Technology, a start-up that is developing new, cost-effective materials of importance for electronic device applications.

According to a winter (November) 2012 online news story article released by the Harvard School of Engineering and Applied Sciences (featured on the Harvard University web site's home page), Hu is exploring the use of gallium nitride wafers at the nano-scale level in the formation and use of quantum dots in nanophotonics (the study of and manipulation of light via materials- photonics- at the nano-scale level), which could eventually find use in smartphone screens and the (less-risky, non-invasive) fluorescent tagging of biological cells for their study in health and disease.
