Short CV

Laura Docío-Fernández received her MSc degree and PhD in Telecommunications Engineering from the Universidade de Vigo (Spain) in 1995 and 2001, respectively. She has participated in more than 15 research projects funded by national or international public institutions and companies. She is the author of more than 40 papers published in international conference proceedings. In 2002 she was a Postdoctoral Fellow in the International Computer Science Institute (ICSI) of Berkeley, USA. She is currently an Associate Professor in the Department of Signal Theory and Communications at the Universidade de Vigo, Spain, and a member of the Multimedia Technologies Group (GTM). Her research interests lie in the broad field of speech and audio processing, especially the analysis, modelling and recognition of speech, speaker and audio signals in general. She has participated in several Albayzin Evaluation Campaigns organized by Spanish National Network on Speech Technology; specifically, she has participated in Albayzin 2010 and 2012 Audio Segmentation Evaluations, in Albayzin Speaker Diarization Evaluation and in Albayzin 2010 and 2012 Language Recognition Evaluations.
