Shuiqing Hu is currently a doctoral student in the School of Mechanical Engineering and the Birck Nanotechnology Center at Purdue University working with Prof. Arvind Raman in the field of nonlinear dynamics in dynamic atomic force microscopy. Earlier he earned his master (2001) and bachelor’s (1998) degree in acoustics from the Nanjing University, P.R. China. His reseach interests lie in predicting and exploiting nonlinear dynamical phenomena in micro and nanosystems. Shuiqing received two years Frederick N. Andrews Fellowship (2001-2003) and Purdue Research Foundation Fellowship (2003-2007) in Purdue University.
