Dr. Shum is an experimentalist in studying semiconductor nanostructures for optoelectronic applications such as light emitter, photodetectors, and light modulators. He is also an educator on semiconductor device physics. Prior to joining the Brooklyn physics faculty, he was a senior design and validation engineer at TriQuint Semiconductor from 2003 to 2005. He held a position of Distinguished Member of Technical Staff at Bell Laboratories/Lucent Technologies and Agere Systems from 2001 to 2003. Dr. Shum was a tenured full professor in the electrical engineering department at the City College of New York from 1998 to 2001. He is the author of over 50 papers and 3 U.S. provisional patent applications.

Education:
DOCTOR OF PHILOSOPHY, The CITY UNIVERSITY OF NEW YORK - 1987 (ELECTRICAL ENGINEERING)

Areas of Expertise:
My expertise is to design, to fabricate, and to characterize semiconductor nanostructure based optoelectronic devices based on the fundamental understanding of photon-electron interactions in semiconductors.

Doctoral Rotation Projects:
My renewed research interest focuses on the exploratory work from novel materials synthesis to device innovation using known physics. Currently there are three funded research projects (please visit Professor Shum?s website) and a few other active projects for attracting external research funding. Professor Shum's nanophotonics laboratory is equipped with a few essential experimental apparatuses for measuring photoluminescence/electroluminescence spectra, photoluminescence excitation spectra, Raman spectra, absorption/transmission spectra, and time-resolved photoluminescence spectra. Through the shared equipment on the campus, this laboratory is also capable of synthesizing new materials and their nanostructures. Students in a PhD/Master program are welcome to explore the capability of this research laboratory.

Creative Work
Created one of the most advanced research laboratories in the City University of New York system. This laboratory located in 147-149NE is now capable of carrying out many research projects in the area of nano-materials/structures based optoelectronics. 2007

Research Activities
A paper entitled "Synthesis of uniform ZnO nanowire arrays over a large area" has been accepted by NSTI Nanotech 2008 conference.
A sponsored research agreement has been signed between FirstNano/CVD and CUNY Brooklyn College/NYSTAR-CAT to develop ZnO nano materials and related devices. 2008
