brief bioGRAPHY

Matías Zañartu received the B.S. and professional (C.E.) degrees in acoustical engineering from Universidad Tecnologica Vicente Perez Rosales, Santiago, Chile, in 1996 and 1999, respectively, and the M.S. degree in electrical and computer engineering in 2006 from Purdue University, West Lafayette, IN, where he is currently working toward the Ph.D. degree in electrical and computer engineering. Since 2006, he has been a Research Assistant at Purdue University. In 2009 he was a Graduate Intern Technical at the Physical Technologies Laboratory from Intel Corporation, working on advanced non linear filtering techniques to improve the performance of voice command and speech recognition. During 2008, he was a Visiting Researcher at the Center for Laryngeal Surgery and Voice Rehabilitation, Massachusetts General Hospital, Boston. His current research interests include biomedical acoustics, speech production, acoustic phonetics, and auditory and speech signal processing. Mr. Zañartu was the recipient of a Fulbright Scholarship, an Institute of International Education IIE-Barsa Scholarship, a Qualcomm Q Award of Excellence, and a Best Student Paper in Speech Communication in the157th meeting of the Acoustical Society of America in Portland, 2009.
