Open Positions











Immediate Opening in Opto-Mechanics:

This project investigates mechanical response of materials under optical excitation, in particular, amplification of optical force on nano-structured materials such as plasmonic materials. Applications of this research include optical actuated mechanical devices for microelectronics and opto-electronics.

We look for applicants with background and interest in mechanics (mechanical engineering or physics), and/or optics.

Undergraduate Research Opportunities:

Undergraduate students are participating in our research work through taking ME497, Independent Research, Discovery Park Research Internship (DURIP), or Summer Undergraduate Research Fellowships (SURF). Previously accomplished ME497 projects include heat transfer, laser micro-/nano-machining, 3D additive manufacturing, laser nanomaterials growth, and nanoscale heat transfer. Email Prof. Xu for more details.


Please note summer internships are not available for international students not in the US at the time of application.


Information for M.S., Ph.D., and postdoc applicants:


We look for highly motivated students with background in one or more of the following areas:

-        Mechanical Engineering, including Heat Transfer, Thermal Science and Precision Instruments

-        Electrical Engineering in Ultrafast Optics

-        Physics, particularly in Solid State Physics, Mechanics and Optics

-        Laser manufacturing and laser diagnostics

-        Microfabrication, i.e., lithography


Typical successful applicants had solid background and excellent academic record in his/her field of study, in addition to meeting the minimum requirement of the ME graduate school.



Note for International Applicants: Exceptions could be made if your GRE scores do not meet the minimum requirements of the ME graduate school. However, one must demonstrate exceptional accomplishments in other areas. For more information, please contact Prof. Xu


Current Open Positions:



1. Ultrafast energy transfer in nanomaterials. This project utilizes an ultrafast laser system to investigate electron and phonon transport processes in nanoscale materials, such as supperlattices and quantum dots typically used for solar and thermoelectric energy conversion applications, and 2D materials such as black phosphorous. Background and prior experience in one of the following areas are desirable: heat transfer, solid state physics, and ultrafast laser/optics.


1. Nanoscale optics and nanomanufacturing.   This project is to study optics at nanoscale and apply nanoscale optics in applications including nano-manufacturing and data storage. We have developed nanoscale optical antennas for concentrating light into nanoscale, which are used as light sources for nano-lithography, concentrated energy source for nanomaterials growth, and for information storage. Research positions are in the areas of nanoscale optics and/or optical measurements (NSOM) and micro-and nano fabrication. Background in mechanical engineering, physics, or electrical engineering is desirable.
