Microelectronic and in 1993 the PhD in Semiconductor Materials both from the New University of Lisbon. She is a full

professor since 2011 in Electronics inside the Department of Electronics Telecommunication and Computers (ISEL-

Portugal) and the head of a Group in Applied Research in Microelectronic Optoelectronic and Sensors-GIAMOS in ISEL

and another in Microelectronic, Material and processes-(M2P) in CTS-UNINOVA. She has several scientific papers and 30

years of experience in the field of thin films and devices, her research activities have been mainly related to the

development of optical sensors .

• Research in the first phase (1987/1996) took place in “Centro de Física Molecular da Universidade de Lisboa”–CFM and

“Centro de Excelência de Microelectrónica e Optoelectrónica de Processos “-CEMOP-UNINOVA. Research in the second

and third phases takes place under her own coordination in “Grupo de Investigação Aplicada a Microelectrónica,

Optoelectrónica e Sensores” (GIAMOS ISEL-DEETC) (1997/...) and in group “Microelectrónica Materiais e Processos

(M2P)” in “Instituto de Desenvolvimento de Novas Tecnologias da Faculdade de Ciências e Tecnologia da Universidade

de Lisboa”.

• Other scientific activities:

• Referee for international publications such as: Thin Solid Films, Material Research Society, Sensor Magazine, Sensor and

Actuators, Material Science Fórum, Solid State Electronics, Vacuum, Applied Surface Science, Sensors and Transducers,

Revista Ibersensors, Physica Status Solidi, Sensors, Journal of Nanoscience Nanotechnology, Journal of Sensors, Journal

of Signal and Imaging Systems Engineering (IJSISE), etc.

• Referee for several EU projects as part of the Programme Growth “Innovative Products, Processes and Organisation“.

• Supervision and co-supervision of Master and PhD students

• Examiner for Master and Doctoral degrees.

• Authored and co-authored more than 300 publications in international journals cited in “Science Citation Index”. Presented

more than 400 communications at conferences and seminars most of which with publication in journals and proceedings.
