Zañartu's poster was presented in the special session on source-filter interactions in biological sound production. The paper was co-authored by Julio Ho from the Weldon School of Biomedical Engineering at Purdue University, Daryush Mehta from MIT-Harvard, Robert Hillman from MGH/MIT-Harvard, and Professor George Wodicka, also of the Weldon School. The project is part of the collaboration between the Wodicka laboratory and Professor Robert Hillman, Research Director of the Center for Laryngeal Surgery & Voice Rehabilitation at the Massachusetts General Hospital in Boston, MA.

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. He is currently working toward a Ph.D. degree in electrical and computer engineering. Since 2006, he has been a Research Assistant at the Weldon School.

In 2009 he was a Graduate Intern Technical at the Physical Technologies Laboratory from Intel Corporation, working on advanced nonlinear 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.
