Research Assistant Hiring, Fall 2019

I am looking for 4 graduate research assistants (M.S. or Ph.D.) starting from Fall 2018. A higher priority is given to Ph.D. program applicants regarding financial supports. Applicants with their B.S. degrees are highly encouraged to apply for the Ph.D. program if you have a strong interest. Please DO NOT worry that you do not have an M.S. degree.   

Next year, I am looking for applicants who have been taking classes or research experience in one of the following areas:

1)   Power engineering: power electronics, electric machines, drives, power systems, high voltage engineering.

2)   Mechanical engineering: statics and dynamics, mechanics of materials, thermodynamics, heat transfer, manufacturing processing engineering, kinematics and mechanism design. 

If you are interested in working with me or have questions, please email me with the following info or your questions.  

-       Resume.
