Lab Manager of the New Microfluidics Thrust Area Lab & Researcher

Introduction

My current research interests are in SQUID Superconductor thin film technology, thin film deposition of novel nanostructures of  ZnO nano rods and their Piezo electric effects and integrating this technology into MEMS structures, using sputtered thin film layers on membrane technology and integrate the photo catalytic effect of TiO2 to improve bio-fouling and membrane clogging.

Research Interests

Another of my interests is using the electro-spinning technique to generate TiO2 crystalline structures for photo catalysis. Also interested the integration of this technology into super-capacitors, nano filters and combine this technology into solar cells. Generally thin film technology, either via PLD, sputter techniques, PVD and CVD is the field I am most familiar with.
