Sander Gierkink received the M.Sc. (cum laude) and Ph.D. degrees in Electrical Engineering from the University of Twente, The Netherlands, in 1994 and 1999 respectively. His Ph.D. topic was on jitter and control linearity of relaxation oscillators.

In 1999 he joined Bell Laboratories, Lucent Technologies, Murray Hill, NJ. In the Communications Circuits Research department his focus was mainly on LC oscillator design for 802.11 WLAN. He continued to work for Agere Systems after it was spun off from Lucent.

In 2004 he joined Globespan Virata, Redbank, NJ, where he worked on topics like phase- and delay locked loops and ADSL linedriver  design.

In 2008 he joined Axiom IC, Enschede, The Netherlands, which was later acquired by Teledyne Dalsa in 2013. Currently he works on the design of read-out ICs for uncooled TEC-less infrared micro-bolometer cameras.

Sander Gierkink received the 1999 Else Kooi Award for his Ph.D. research, the 1998 Young Scientist Award and the 2003 Best Paper Award, both of the European Solid-State Circuits Conference, and the 2007 Best Regular Paper Award of the IEEE Custom Integrated Circuits Conference.
