research publications

I am a Tenured Associate Professor and a Serra Húnter Fellow at the Department of Information and Communication Technologies (DTIC) of the Universitat Pompeu Fabra (UPF) where I lead a team composed by 3 PhD students under my supervision and myself (BERG). Before obtaining tenure in December 2014, I benefited from a Ramón y Cajal fellowship and a Marie Curie IRG grant at the UPF.
Prior to joining the UPF, I enjoyed a three-year postdoctoral position at the University of California at Berkeley (2005-2008) followed by an appointment as Assistant Research Engineer at the same institution for a year. Then I moved to Villejuif, France, for an eight-month postdoctoral position at the Centre National de la Recherche Scientifique (CNRS) - Institut Gustave Roussy. During 1998-2005, I was with the Biomedical Applications Group of the Centre Nacional de Microelectrònica, Bellaterra, Spain. I received a PhD in Electronics Engineering from the Universitat Politècnica de Catalunya, Barcelona, Spain, in 2005.

My research is mostly focused on bioelectrical phenomena and on exploring the use of these phenomena for implementing new methods and devices for biomedical applications. Specifically, my main research topics are electroporation (), particularly for cancer treatments, electrical bioimpedance (Ω) for medical diagnosis and electrical stimulation for neuroprosthetics ().

My teaching activities are focused on basic circuit theory, basic electromagnetism, bioelectromagnetism, instrumentation systems and advanced analog electronics in general, and in particular signal conditioning circuits and medical instrumentation systems.
