Biography

Perales is a Metallurgist graduated from the Universidad Nacional de Ingeniería (UNI) in Perú. After working in the School of Metallurgy at UNI as a professor and consultant engineer for more than 10 years, Oscar moved to the Institute for Advanced Materials Processing, Tohoku University in Japan, where he got his Ph.D. in Materials Processing in 1998. Perales was invited to join the Center for Interdisciplinary Research, Tohoku University (CIRTU) as a Visiting Associate Professor in November 1998. At CIRTU he was involved in research related to size-controlled synthesis and characterization of nanostructures and development of sizeselective separation methods for nanosize polydisperse crystals. Perales also worked as a member of the research team SONY-Tohoku University, being co-inventor of processes related to the size-controlled synthesis of magnetic nanomaterials.

Perales is with the Department of Engineering Science and Materials of the University of Puerto Rico, Mayaguez Campus (URPM) since 2002 and his current research interest involves the size, shape and structure-controlled synthesis of nanostructures (nanocrystals and thin films) for spintronics, high-density storage, electronic cooling and magnetocaloric applications. New research initiatives in nano-medicine are focused on the processing of quantum dots for Photo Dynamic Cancer Therapy (PDT). Perales projects are oriented towards the testbed stage through the Institute for Functional Nanomaterials (IFN) and strategic partners at the University of Wisconsin-Madison (MRSEC and MSE Department) and the National High Magnetic Field Laboratory in Florida. The competitiveness of Perales' work is demonstrated by the support he receives from several agencies including the National Science Foundation, the United States Department of Defense, the United States Department of Education, IDEAS, the United States Geological Survey, the Puerto Rico Water Resources and Environmental Research Institute, the Toyota Foundation, The Water Management Authority and The Waste Solid Management Authority. He is also Co-director of the 5-years NSF-PREM Project on Functional and Nanostructured Materials.

Perales, two times Distinguished Professor of the College of Engineering at UPRM, is author of more than 50 scientific and technological publications in materials processing and nanotechnology. He has also participated as invited panelist for the National Science Foundation SBIRT/STTR Program since 2003 (Functional Nanotechnologies and Advanced Materials).
