Marcello R. B. Andreeta earned his PhD in Materials Science and Engineering in 2001 from the Physics Institute of São Carlos (IFSC), University of São Paulo (USP - Brazil), after experimental research collaboration with the University Autónoma de Madrid (Spain) and Stanford University (USA). His major field of research is the development of new strategies for the preparation of materials and devices by laser-heated process. His research interests include solid state lasers, crystallization process, ceramics, oxide glasses, solid state sensors and X-ray diffraction. Currently, he is developing new glass and crystalline compounds for optical and electric devices using the Laser-Heated Pedestal Growth technique at the Federal University of São Carlos (Materials Engineering Department - UFSCar/DEMa) in São Carlos, SP, Brazil. He is the author of more than 60 papers in international peer-reviewed journals, 2 book chapters and edited the book "Crystallization: Science and technology". He is also the member of the Editorial Board of "Eureka: Physics and Engineering" and Associate Editor of the "Open Chemistry Journal".
