Junliang Dong received his Master degree in Control Science and Engineering in 2011, from Tsinghua University, China. His Master dissertation focused on ultrasonic nondestructive evaluation. In August 2013, He started to pursue his Ph.D. related to terahertz imaging and spectroscopy in Georgia Institute of Technology, USA, under the supervision of Prof. D. S. Citrin. In June 2017, he successfully defended his Ph.D. thesis entitled ‘Terahertz Imaging for Nondestructive Evaluation and Material Characterization’. His Ph.D. mainly focused on developing novel techniques to enhance the capability of terahertz imaging for the applications in industry and cultural heritage conservation science. Since August 2017, he joined the Nonlinear Photonics group of Prof. R. Morandotti as a postdoctoral research fellow, where he is investigating terahertz generation/detection, terahertz waveguide, as well as terahertz imaging and spectroscopy for biomedical applications.
