Raquel Mejia-Ariza was born in Pereira, Colombia on June 27, 1982. She studied Chemical Engineering at the University of Puerto Rico at Mayagüez. After graduating in 2006, she went to Virginia Polytechnic Institute and State University where she got a master's degree in Macromolecular Science and Engineering. For her master's project she designed, synthesized, and characterized magnetite clusters using a multi-inlet vortex mixer under the direction of Dr. Richey M. Davis.

From January 2011 until May 2015, she performed her PhD project in the MnF group of Prof. Dr. ir. Jurriaan Huskens at the University of Twente. The aim of her research was size tuning and surface functionalization of supramolecular nanoparticles and metal-organic frameworks for biomedical applications.

Since May 2015 she works as a postdoc in the MnF group on the Nanopil 2.0 project on the development of a bladder cancer detection kit in collaboration with other groups at the University of Twente ( and on the fabrication of an electronic nose using functionalized cantilevers for disease detection via breath diagnostics.
