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.

Hannah Flinn is a current post baccalaureate student at Rice University. She obtained her bachelor’s degree in Biomedical Science from Texas A&M University in August 2021, with a primary focus on Veterinary Medicine. As part of the Villapol lab, Hannah is involved in studying the link between the brain and gut microbiome via the gut brain axis and identifying various mice models of Alzheimer’s disease and pathology. The next step in Hannah’s career is to pursue her PhD in Neuroscience to continue her passion for research and neurology. She hopes this will allow her to focus on continuing to investigate Neurodegenerative diseases and get more insight on blood brain barrier interactions and integrity in disease models. Outside of the lab, Hannah enjoys being a dog-mom to her rescue dog, Wilson, and finding the best coffee shops in Houston.
