    Biography 

    Laura Fernández studied Telecommunications Engineering at the University of Granada, Spain, majoring in digital signaling and telecommunication networks.

    She completed her master’s degree in 2011 and joined the Quality and Usability Lab of Deutsche Telekom Laboratories in Berlin, where she worked as intern during three months. In November 2011, she began working towards her PhD thesis in the domain of speaker recognition in wideband VoIP services. This project was conducted under a research and development agreement between Deutsche Telekom AG, Germany and the University of Canberra, Australia.

    In June 2015, Laura was awarded the PhD for her work "Human and Automatic Speaker Recognition over Telecommunication Channels", supervised by Prof. Michael Wagner and by Prof. Sebastian Möller. She continues working at the Quality and Usability Lab on speech-related topics. She is particularly interested on the detection and prediction of speaker personality and voice likability over communication channels.
