His Research activities are concerned with the development of chemical and biological sensors, artificial sensorial systems (olfaction and taste) and their applications, sensor interfaces, data processing. He authored more than 150 peer-reviewed papers on international journals and conference proceedings. He has been responsible of three experiments during the ENEIDE Space Mission on the International Space Station (April, 2005) and of one research project with the Italian Space Agency (2006). Dr. Martinelli is also Principal Investigator of three projects (National Institute of Health and Veronesi Foundation Grants) on the development of sensorial systems for medical applications (cancer identification, tuberculosis). He is also member of the “IEEE task Force on Computational Intelligence for Chemometric and Chemical Sensing”.
