Professional Experience

Junho 2015 - Presente Researcher at University of Aveiro (Portugal). Colaboration with the University of Copenhagen (Denmark) - Michael Kühl Team. Project: Molecular and photochemical insights on the retention of functional chloroplasts by metazoan cells. Funding: Fundação para a Cência e a tecnologia (FCT - Programa IF 2014).


April 2011 - May 2015 Postdoctoral Researcher at University of Aveiro (Portugal) in colaboration with the University of Copenhagen (Denmark), funded by Fundação para a Ciência e a Tecnologia (FCT): SFRH/BPD/74531/2010 (April 2011 - March 2014), SFRH/BCC/52508/2014 (April 2014 - November 2014), SFRH/BPD/97027/2013 (December 2014 - May 2015). Project: Cracking the puzzle of solar powered sea slugs - molecular and photochemical insights on the retention of functional chloroplasts by metazoan cells.


January 2010 - March 2011 Postdoctoral Research Associate at the Department of Plant Sciences, University of Cambridge (UK). Investigated the potential of using photosynthetic microorganisms in a photovoltaic-type device to generate electricity. My main focus was to understand how electrons flow from the chloroplast to the external environment.
