Marta Cerruti is a chemist who specializes in the characterization and optimization of phenomena occurring at the interface between synthetic materials and biomolecules. She received her PhD in 2004 at the University of Torino, working on the application of techniques typical of physical chemistry to the study of bioactive glass surfaces, and how they changed upon immersion in simulated body fluids. Part of her PhD research was conducted at the University of Florida, in collaboration with Novamin Technologies, the company that at the time produced Bioglass® (BG). After her Ph.D. she worked as a post-doctoral fellow at North Carolina State University for 2 years, and then at UC Berkely for another 2 years. During these 2 post-docs she studied DNA sensors, explosive detection, graphene functionalization, RNA-mediated nanoparticle synthesis, and antimicrobial surfaces.

In September 2009 she joined the Department of Mining and Materials Engineering at McGill University as Assistant Professor. Her main interests are understanding and controlling surface phenomena, especially at the interface between synthetic materials and biological molecules. Current research focuses on three main thrusts:

(i) Biodegradable composite polymer/BG scaffolds: the scaffolds are prepared with different techniques that allow for variable control of the porosity; we strive to understand how BG and the polymeric matrix interact at their interface, control the scaffold degradation rate, and functionalize its surface so that it can enhance bone repair once implanted

(ii) Influence of biomolecules on hydroxyapatite (HA) crystallization: HA is the inorganic component of bones, and its nucleation and growth in the body is controlled by non-collagenous proteins. We strive to understand the functionalities in these proteins that induce or inhibit HA crystallization, and use smaller sequences (oligopeptides or even amino acids) to nucleate and grow HA in-vitro with controlled morphology at desired locations on model surfaces.

(iii) Oral delivery of calcitonin: this project is performed in collaboration with professor Jake Barralet, from Dentistry. We want to functionalize the surface of calcitonin carriers to allow absorption through the intestinal membrane
