Rong Wu was born on November 4, 1981. She received the [...]. degree in microelectronics from Fudan University, Shanghai, China, in 2003. After one year of graduate studies in Fudan, she started the [...]. program in electrical engineering at Delft University of Technology, Delft, the Netherlands, in September, 2004. She received her [...]. degree from TU Delft in February 2006 and her [...]. degree from Fudan University in July, 2006, both in electrical engineering.

In October 2006, she joined the Electronic Instrumentation Laboratory of the TU Delft, pursuing her Ph.D degree on the subject of precision amplifier and sigma-delta ADCs for sensor read-out. In December 2011, she received her Ph.D degree. Currently, she is with precision ADC group of Analog Devices in Wilmington, MA. Her research interests include sensors, precision analog and mixed-signal interface electronics.
