Anderson T. Hara, DDS, MSD, PhD holds the position of Assistant Professor in the Department of Preventive and Community Dentistry at the Indiana University School of Dentistry (IUSD). He serves as Director of the OHRI Laboratory Research Core/Facility, the OHRI Laboratory Contract Testing Program and the Digital Electron Microscopy Facility. Dr. Hara also directs the OHRI Dental Erosion-Abrasion Program. Dr. Hara is originally from Brazil where he received his Dental, Master and PhD degrees from the School of Dentistry of Piracicaba at the State University of Campinas. His research activities in dentistry started in 1996, when as an undergraduate student he was awarded with his first research scholarship. He received his Dental degree in 1997 and his MSD in 2001, being accepted months later as a PhD student at the same University. In 2003, he was a research scholar at the OHRI/IUSD, in a "PhD sandwich program". In 2004, back in Brazil, he defended his PhD thesis. In 2005, he returned to the Indiana University as a post-doctoral fellow and in 2006 Dr. Hara joined the faculty at the OHRI/IUSD as a Visiting Assistant Professor. In 2009, he accepted the positions of Assistant Professor (tenure-track) and Director of the OHRI Laboratory Research Core/Facility and Director of the OHRI Laboratory Contract Testing Program. He has published more than 50 research articles in peer-reviewed international scientific journals and has obtained substantial external funding for in vitro testing and research and development projects. Currently, he is involved in research projects related to Dental Erosion-Abrasion, Remineralization and Secondary Caries.
