Prof. Gema Piñero Sipán

Gema Piñero (Ms. Telecommunications Engineering, Universidad Politécnica de Madrid ‘90; Ph.D. Engineering, Universidad Politécnica de Valencia ’97) was born in Madrid (Spain) in 1965. She is currently an Associate Professor at the Universidad Politécnica de Valencia.

Since 1990 she has been involved in different research projects including array signal processing, mobile communications and sound quality in the Audio and Communications Signal Processing (GTAC) group, www.gtac.upv.es, of the Institute of Telecommunications and Multimedia Applications (iTEAM) of Valencia. In 1999 she leaded several research projects on sound quality evaluation for the automotive industry. Since 2001 she has leaded or participated in several projects on WCDMA and 4G wireless communications supported by public and private funding (Spanish Government, Regional Government, Telefónica, NVIDIA). She has also published more than 50 contributions in journals and conferences on signal processing algorithms for sound and communications applications. Her current research interests include coordinated systems and spatial division multi-user techniques in wireless communications, and adaptive algorithms for distributed sensors in audio applications.

She is a senior member of the IEEE and founding member of the Spanish Association for Research and Teaching UNIVERSITAS.
