Guido Baroni obtained the Master degree in Mechanical Engineering at the Politecnico di Milano in 1993 and the PhD degree in Bioengineering in 1999. In 2001, he was appointed Assistant Professor and in 2010 he was promoted to the position of Associate Professor in Biomedical Engineering at the Department of Electronics Information and Bioengineering of the Politecnico di Milano. He teaches “Technologies for Computer Assisted Surgery” and “Human Motion Virtualization” in the Biomedical Engineering master program and “Experimental Design and Statistics” in the Bioengineering PhD program. His interests cover technologies and methods for 3D/4D optical tracking and biomedical imaging, with applications in surgical navigation and image guidance in photon and particle radiation therapy. His research activity is documented by more than 200 peer-reviewed international papers on stereophotogrammetry, human movement biomechanics, motion tracking and imaging in high precision radiotherapy. He is responsible of the Computer Assisted Radiotherapy and Surgery Laboratory (www.cartcas.polimi.it) of the Bioengineering Section of the Department of Electronics Informatics and Bioengineering of the Politecnico di Milano; he leads the project 4-D Computer Aided Patient Positioning in Hadrontherapy at the Centro Nazionale di Adroterapia Oncologica (CNAO, www.cnao.it), where he is responsible of the Operative Unit of Clinical Bioengineering, operating in the development and application of image-guidance and adaptive strategies in proton and carbon-ion radiation oncology.
