Summary
I was born in Granada, in 1984. During my undergraduate years, I participated in several research projects;
I was awarded with the Excellent Academic Performance grant during five consecutive years; and I was a
finalist in some prestigious competitions. I received the B.S. degree in Telecommunication Engineering and
the B.S. degree in Business Administration and Management from the Universidad Europea de Madrid,
Spain, in 2008. From 2008 to 2009, I was a consultant in Telecommunication, Media and Technology with
Deloitte S.L., Madrid, Spain. In 2010, I received the M.S. in Multimedia Technologies from the University of
Granada, Spain; and I founded Inggra Solutions S.L., through which I executed several Common Telecommunication Infrastructure (CTI) projects. In 2014, I received the Ph.D. degree from the University of Granada,
Spain. I have published in several impact-factor journals, I have participated in international conferences, I
am involved in several international research projects, I am a reviewer of a number of international journals,
and I am an assisstant lecturer in the B.S. degree in telecommunication engineering.
My main research fields of interest include the recording of auditory responses at high stimulation rate, the
mechanisms involved in the process of hearing, the computational modeling of the auditory system, and
signal processing methods for automatic assessment of auditory responses and artifact rejection techniques.
