Dr Conrado Aparicio is an investigator with a research focus on the surfaces of dental biomaterials, their design, modification, as well as the characterization and analysis of their physical, chemical, mechanical, and biological properties. He is a materials engineer by training and performed his PhD under the supervision of Professor Javier Gil at BarcelonaTech-UPC developing new surface treatments to improve osseointegration of dental implants.

After getting his position as a senior lecturer in Spain, Dr Aparicio moved to Chicago where he was a visiting scholar at the Institute for BioNanotechnology in Medicine of Northwestern University under the supervision of Professor Samuel Stupp. Dr Aparicio investigated the biomineralization of self-assembled nanostructured scaffolds made of peptide-amphiphiles.

Dr Aparicio’s main subjects of research are the understanding of the interactions between biological and synthetic materials, biofunctionalization of biological and synthetic surfaces with biomolecules for improving bioactivity and antimicrobial properties of different dental biomaterials, and biomineralization of biomaterials.

Recently, Dr Aparicio’s research interests have expanded to studying and developing new techniques and new biomaterials, including 1) dental restorative materials and biological agents to induce bone regeneration and teeth remineralization; and 2) new materials and methodologies for the assessment, management, and improvement of esthetic dental restorations.

Dr Aparicio’s background and record of scholarly publications reflects a multi- and interdisciplinary approach to biomaterials and biomechanics science and engineering, including several biomolecular, in vitro and in vivo studies.
