    Beatriz H. Juárez is associated professor at the Universidad Autónoma de Madrid (from Sep 2012) and former researcher in the “Ramón y Cajal” programme at IMDEA Nanoscience (2008-2012). She received a B.Sc. degree in Chemistry from the Universidad Complutense de Madrid (UCM) in 1999 and a Ph.D degree in Material Sciences from the Universidad Autónoma de Madrid (UAM) in 2005. The topic of her dissertation focused on Photonic Crystals and was supervised by Prof. C. López (http://luxrerum.icmm. csic.es/). Dr. H. Juárez also worked for almost 2 years in Lucent Technology, a factory devoted to the fabrication of microelectronic circuits in a clean room laboratory. After finishing the PhD, she moved to the Laboratoire de Photonique Quantique et Moléculaire (LPQM) in Paris. After a short stay, she joined the group of Prof. Dr. Horst Weller in Hamburg (https://www.chemie.uni-hamburg.de/pc/weller/index_e. html) with a Marie Curie Individual Intra European Fellowship. Dr. Juárez received in 2009 the junior nanotechnology prize given by AGENT-D.

    Research Lines

    The nanoparticles laboratory (http://www.nanoscience.imdea.org/nanoparticles-lab) is mainly dedicated to the synthesis of colloidal semiconductor nanoparticles (quantum dots). The research lines include the synthesis of colloidal nanocrystal and hybrid systems, further processing, surface chemistry studies and optical characterization. In the last years, special focus has been given to hybrid systems composed of semiconductor nanoparticles and carbon sp2 materials, such as carbon nanotubes and flat graphitic surfaces. In collaboration with J.R. Arias-González, optical trapping of quantum dots in also the focus of recent research. (http://www.ariasgonzalez.com/onm---people.html)
