Prof.dr.ir. R.G.H. Lammertink | People Pages: Find employees & contact details

I received my PhD (2000) in Chemical Engineering from the University of Twente. I subsequently started a postdoctoral project at the California Institute of Technology. At the beginning of 2004, I was appointed as assistant professor in the Membrane Technology Group. In this group, I performed research related to microstructured interfaces for membrane applications. This activity was extended into fields of microreactor technology and microfluidics (Vidi 2007). As of April 2010 I am heading the Soft matter, Fluidics and Interfaces group. The research focuses on interfacial aspects in relation to mass and heat transport (ERC 2012, Vici 2016). These studies promote the fundamental understanding of transport phenomena near interfaces that are important for membrane and catalytic processes.

Organisations

My research is directed at interfacial phenomena and processes that are relevant for mass and heat transport. I wish to study and exploit fundamental principles where fluid flow encounters structures on a sub-millimeter length scale.
