Biography

Guiomar Evans was born in Barreiro, Portugal, in 1966. She received her degree in Physics Technology from the Faculdade de Ciências da Universidade de Lisboa in 1991, the M.Sc. degree in Materials Engineering from the Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa in 1996 and, the Ph.D. degree in Physics – Speciality of Electronics and Instrumentation from the Faculdade de Ciências da Universidade de Lisboa in 2006.
From 1990 to 1998 she has been working as a Senior Engineer of the Digital Signal Processing and Optoelectronic Department at the Empresa de Investigação e Desenvolvimento de Electrónica S. A. (E.I.D.), a Portuguese engineering company specialized in telecommunications and military electronic applications. From 1998 to 2006 she was Assistant Professor and since 2006 she is Auxiliary Professor in the Departamento de Física at the Faculdade de Ciências da Universidade de Lisboa. Since 2002 she has been working as a Collaborator Research of the Centre for Technology and Systems (CTS) at UNINOVA and, since 2006 as a Senior Research at the Centro de Física da Matéria Condensada, of the Departamento de Física at the Faculdade de Ciências da Universidade de Lisboa. She is also a member of the ATLAS/LHC/CERN Portuguese Tilecal team since 2006.
Her interests include the design of low-power and low-voltage analog integrated circuits, noise generators, built-in self-test and built-in self-calibration of ADCs, digital signal processing, reconfigurable systems, measurement of the AC magnetic susceptibility at high temperatures and resistivity measurements at low temperature of nanostructured magnetic nitrides.
