Dr Tiago G. Fernandes is currently a Post-doctoral research fellow at the Institute for Biotechnology and Bioengineering, Lisbon, Portugal. His research interests are focused on the development of artificial cellular niches for studying the mechanisms that affect human stem cell pluripotency, and the cellular and molecular events that regulate stem cell functions. During his doctoral studies he also worked at the Rensselaer Polytechnic Institute, NY, USA, in the development of microscale platforms for high-throughput studies of stem cell fate.
