Roberto Piñeiro Cid

Head of the Cancer Modelling Line of the Roche-Chus Joint Unit

Roberto Piñeiro completed his doctoral studies on the biology and metabolism of cardiomyocytes in 2005, at the Department of Medicine of the University of Santiago de Compostela. In 2007 he joined the Phosphoinositide group for his post-doctoral in the Blizard Institute, Queen Mary University of London, where he studied the role of the GPR55 receptor and its ligand, lysophosphatidyl inositol (LPI) on cell proliferation in prostate and ovarian cancer.

Then in 2011 he was incorporated into the Cell Signalling group of Barts Cancer Institute, Queen Mary University of London, currently located at the UCL Cancer Institute, University College London. In this laboratory, Roberto worked studying the role of Class I PI3K in cell signalling in cancer and the tumour microenvironment using “knock-in” mice and cellular models.

He is currently Head of the Cancer Modelling Line of the Roche-Chus Joint Unit

Experience: animal models, cell cultures, molecular and cell biology, biochemical models.

Interests: ancer cell biology, tumour micro environment, metastasis, oncology, molecular biology.
