Isabel Rozas carried out postgraduate research at the Institute of Medicinal Chemistry (CSIC, Madrid, Spain) obtaining her PhD degree from the Universidad Complutense de Madrid in 1987. She performed post-doctoral research in the University of Saskatchewan (Canada), and at Queen’s University in Kingston (Canada), and in 2000 she moved to the School of Chemistry at Trinity College Dublin (Ireland), where she is now a Professor in Chemistry. Her main area of research is framed within the Medicinal Chemistry field, and, thus, her group works in the modelling, preparation and biophysical and biological evaluation of guanidinium derivatives with different biological applications (i.e. cancer, antiprotozoal, anti-tuberculosis or antiviral). In addition, she has an interest in the theoretical study of non-covalent interactions such as hydrogen bonds. She has published over 170 papers and collaborates with several groups in Ireland, Spain, UK, France, Germany, Italy, India, Canada, and USA. She was an Editor of BMCL and now is a member of the Advisory Board for both BMC and BMCL. Presently, she is the Chairperson of the Division of Medicinal and Biological Chemistry in the ICI (Institute of Chemistry of Ireland) and member of the Council of the European Federation for Medicinal Chemistry and Chemical Biology (EFMC).
