Current Research Interests
Dr. Zhang’s research is highly interdisciplinary. His current research interests focus on fabrication of surface structures from micro- to nano-scale based on micro-contact printing (µCP) and dip pen nanolithography (DPN); scanning probe microscopy (including AFM, CFM, PFM-AFM, etc.); self-assembled monolayers; self-assembly and self-organization of nano- and bio-materials; synthesis, characterization and application of nano-materials.

Biographical Information
Dr. Zhang obtained his B.S. and M.S. degrees at Nanjing University in China in 1992 and 1995, respectively, and completed his Ph.D. with Prof. Zhongfan Liu at Peking University in China in July 1998. He joined Prof. Frans C. De Schryver’s group at Katholieke Universiteit Leuven (KULeuven) in Belgium as a Research Associate in January 1999. Then he moved to Prof. Chad A. Mirkin’s group at Northwestern University as a Postdoctoral Fellow in July 2001. He started to work at NanoInk Inc. (USA) as a Research Scientist/Chemist in August 2003. After that, he worked as a Senior Research Scientist at Institute of Bioengineering and Nanotechnology in Singapore from November 2005 to July 2006. Now he is an Assistant Professor at Nanyang Technological University (NTU). He has published 40+ papers and 20+ patent applications. He is an Associate Editor of International Journal of Nanoscience (2007-) and sits on the Editorial Board of NANO (2007-).
