BASIC RESEARCH TEAM

Picture
Paula Valentina (Paula) Schiapparelli, Ph.D.
Research Associate
Dr. Schiapparelli’s research is focused on understanding the mechanisms by which glioblastoma cells migrate and invade the human brain. Her main project is to describe the mechanisms by which NKCC1 modulates the actin cytoskeleton to regulate cell shape, spreading and migration in glioblastoma.

Virginea de Araujo Farias, Ph.D.
Postdoctoral Fellow
Virgínea graduated in Biology at the State University of Paraíba on 2004 at her home town in Brazil. On September of 2006 moved to Spain to do her Master’s and PhD on Immunology at the University of Granada on the Molecular Oncology research. 
Picture
Beatriz Fernandez Gil Ph.D
Postdoctoral Fellow
Rachel Sarabia Estrada, D.V.M., Ph.D., assists in directing the Brain Tumor Stem Cell Research Laboratory, where she oversees and conducts preclinical studies that are leading to new treatments and methods of delivery for primary and metastatic tumors of the spine and brain. One of her main goals is to lead an integrated research team that focuses on translational and preclinical research to facilitate bench-to-bedside contributions.

Andres Ramos-Fresnedo
Postdoctoral Fellow
Andres first joined Dr. Quiñones-Hinjosa’s team in 2016. A few years later he returned as a research trainee for a period of six months where he helped the clinical team with their research projects, mainly focusing on how the outcomes of different surgical techniques impact the quality of life of neurosurgical patients. 

During his time working with the team, he has volunteered in Dr. Quiñones’ non-profit organization Mission:BRAIN during their outreach trips to Mexico City.
