Sonia Villapol, Ph.D.

Assistant Professor and Neuroscientist👩🏻‍🔬.

Dr. Sonia Villapol is an Assistant Professor and Neuroscientist at the Center for Neuroregeneration and the Department of Neurosurgery at the Methodist Hospital Research Institute in Houston, TX. She completed her bachelor’s degree in Molecular Biology and Biotechnology at the University of Santiago de Compostela (Spain), in 2003. She furthered her education with a master’s degree and Ph.D. in Neuroscience from the Autonomous University of Barcelona in 2007. Following her doctoral studies, she undertook postdoctoral research at the CNRS of Pierre and Marie Curie VI University and the INSERM in Paris (France), and at the National Institutes of Health (NIH), Center for Neuroscience and Regenerative Medicine, and Uniformed Services University in Bethesda, MD in 2010. In May 2014, she joined Georgetown University as a Research Assistant Professor in the Department of Neuroscience before moving to her current position in 2018. Her academic career includes over 70 publications in peer-reviewed journals. Her ongoing research explores neurodegeneration, neuroinflammation, and the brain-gut-microbiome connection, employing animal models for brain injury and Alzheimer’s disease by advancing nanoparticle-based drug delivery systems.

Guillermo Hoppe-Elsholz

Ph.D. Student

Weill Cornell Medicine

Guillermo is a Biochemist from the Pontificia Universidad Católica de Chile, starting his graduate studies in the Physiology, Biophysics, and Systems Biology (PBSB) PhD program at Weill Cornell Medicine – Houston Methodist. His previous research was focused on the pathogenicity of Salmonella enterica serovar Enteritidis and on the development of a probiotic formulation with therapeutic properties. He also worked on the phase III clinical trials of the CoronaVac vaccine in Chile at the Millenium Institute on Immunology and Immunotherapy. Now, in Dr. Villapol’s laboratory, Guillermo’s focus shifts toward the modulation of intestinal microbiota as a therapeutic approach to mitigate the pathology associated with Alzheimer’s disease. His hobbies are Judo, exercising, baking bread, and cooking.
