Where Ideas grow
Andreia Almeida
PhD Student

I am graduated in Biomedical Engineering at the University of Porto (UP) since 2016 and started a PhD in Biomedical Sciences at INEB/i3S, Institute of Biomedical Engineering/Institute for Investigation and Innovation in Health (UP) in 2017, in collaboration with Vall d'Hebron Research Institute (ES) and University of Minho (PT). Also, during my PhD, I conducted three short term scientific missions at Technion - Israel Institute of Technology (IL), University of Seville (ES) and MJRPharmaJet Industry (DE). The main focus of my PhD project is to design a new chitosan amphiphilic derivative with ability to form micelles by self-assembly. These polymeric micelles are able to efficiently encapsulate hydrophobic molecules, as many anticancer drugs, in order to improve its solubility and oral bioavailability. I have extended my expertise on physico-chemical characterization of polymers, as well as in in vitro cell culture studies andin vivo animal models.
