Contract Staff

Aránzazu Martínez Gómez
Research Associate

Aránzazu Martínez Gómez studied Chemistry at the University of Alcalá and received her Ph.D. (2003) working at the Institute of Polymer Science and Technology (ICTP-CSIC) under the direction of Dr. Antonio Bello and Dr. Ernesto Pérez. The topic of her Thesis was “Poliésteres y polioxetanos termotrópicos. Síntesis, propiedades térmicas, mecánicas y fenómenos de orientación”. From 2005 to 2008 she worked as a post-doc (Juan de Cierva post-doctoral position) in the ETS Industrial Engineering of the Polytechnic University of Madrid (ETSSI-UPM). The research was supervised by Dra. Cristina Álvarez and was mainly focused on the preparation of blends and nanocomposites based on polyolefinic matrices. Then, she returned to the ICTP and worked on the synthesis and characterization of new homopolymers and copolymers with liquid crystalline properties in the group of Dra. Mª Luisa Cerrada. In 2010, she joined the Polycondensation and Polymer Membranes group, working in the preparation of new condensation polymers with applications as semipermeable membranes for water purification and gas separation. In 2013-2014 she has worked under the supervision of Dr. Ernesto Pérez on the preparation of smectic liquid crystalline networks with shape memory behaviour.


Álvaro Miguel
PhD. student

Álvaro was born in Burgos in 1991, where he graduated in Chemistry and obtained his master studies in Advanced Chemistry. He started to specialize as a polymer materials chemist at Dr. José Miguel García research group where Álvaro collaborated during his last years at University. During that period, Álvaro focused on structural modification of poly (m-phenylene isophtalamide) to infer certain extra properties to the material, like color or luminescence. The result of those researches were 2 scientific publications, as co-author and author respectively, a patent, as co-author, and a communication at 2016 GEP meeting. While he was doing his master, Álvaro took his first steps in the automotive multinational Grupo Antolín, as a member of the organic materials research group, where he stayed until 2018. This job was a practical complement to the University theoretical training of synthesis and characterization that enriched Álvaro’s knowledge in thermoplastics overall. His main objective has always been to obtain his PhD, which was delayed after he entered in the multinational company. Finally, he joined Instituto de Ciencia y Tecnología de Polímeros (ICTP-CSIC) in March 2018 to work in obtaining solid electrolytes for Aluminum-Sulphur secondary batteries, under Pilar Tiemblo direction, in order to achieve his goal of getting the PhD in polymer chemistry in a near future.

Elisabet Layla Afonso Pérez
