Hiram Castillo Michel

I obtained a Ph.D. in Environmental Science and Engineering from the University of Texas at El Paso, USA in 2011. My research interests focus on the use of synchrotron X‐ray fluorescence (XRF) and X‐ray absorption spectroscopy (XAS) at the micro and nano scale to study the distribution and speciation of trace elements and nanomaterials in biological systems. I joined the European Synchrotron Radiation Facility in 2011 where I have been working at ID21 developing research applications focusing on the characterization of nanomaterials in biological samples and their impact on the environment.
