Dr. Sonia Villapol is an Associate Professor and neuroscientist at the Center for Neuroregeneration and the Department of Neurosurgery, Houston Methodist Research Institute (Houston, TX). She received her B.Sc. in Molecular Biology and Biotechnology from the University of Santiago de Compostela (2003) and completed an M.Sc. and Ph.D. in Neuroscience at the Autonomous University of Barcelona (2007). She pursued postdoctoral research at the CNRS–Université Pierre et Marie Curie (VI) and INSERM in Paris, and later at the National Institutes of Health/Center for Neuroscience and Regenerative Medicine and the Uniformed Services University in Bethesda, MD. In 2014, she joined Georgetown University as a Research Assistant Professor of Neuroscience, moving to HMRI in 2018.
Dr. Villapol’s work, funded by the NIH, Department of Defense, and private foundations, investigates mechanisms of neuroinflammation and neurodegeneration across AD and TBI models, the brain–gut axis, and the development of neurorestorative drug-delivery systems. She has published more than 100 peer-reviewed articles and book chapters.

Morgan Holcomb, B.S.
Research Assistant & Lab Manager
Morgan Holcomb has earned her bachelor’s degree in Biomedical Engineering from Texas A&M University in August 2019. She accepted the invitation to work under the guidance and leadership of Dr. Sonia Villapol at Houston Methodist in February 2021. She is currently involved in a neurorestorative project that fuels her desire to gain experience in research and to further her pursuit of a career in Biomedical Engineering. Morgan appreciates a challenge and spires to make a significant contribution through her research under the mentorship of Dr. Villapol. Though a native of East Texas, Morgan has enjoyed travelling internationally and experienced living in Saudi Arabia for two years. Her desire is to have a positive, global impact in the diverse field of Biomedical Engineering.

Dr. Goknur Kara
Research Associate
Goknur Kara obtained her PhD in Chemistry from Hacettepe University, Ankara, Turkey in 2020. During her doctoral training, she joined the Department of Experimental Therapeutics at the University of Texas, MD Anderson Cancer Center as a visiting PhD student. She later joined the Department of Nanomedicine at the Houston Methodist Research Institute as a postdoctoral fellow. Her research focused on developing molecularly targeted therapies to inhibit tumor growth and tumorigenesis in various types of cancer, utilizing siRNA and miRNA. She has designed several nanoparticle systems to deliver RNA therapeutics into circulation to make these therapies clinically viable. In 2024, she joined the Villapol lab to optimize the nanoparticles for applications in Alzheimer’s disease and to understand the mechanisms driving AD progression by targeting specific signaling pathways responsible for AD pathology.

Marissa Burke
Ph.D. student
Houston Methodist Research Institute / Weill Cornell Medicine
Marissa Burke earned her Bachelor of Science in Aerospace Physiology at Embry-Riddle Aeronautical University in 2022 where she studied spaceflight effects on E. coli and the neuroendocrine-immune axis in mice models. In 2022, Marissa was involved in a simulated galactic cosmic ray exposure experiment at Brookhaven National Lab. She is currently a PhD student at Weill Cornell Medicine within the Houston Methodist cohort. Work Marissa has completed during her time there includes telomerase therapeutics for spaceflight-induced aging, Inspiration 4 astronaut omics studies, and bioinformatics analysis of m6A modifications. As part of the Villapol lab, she has interest in the gut-brain axis and subsequent immune interactions.

Savanna Curson
Undergraduate student
Rice University
Savanna is an undergraduate student at Rice University studying molecular and cellular neuroscience. She joined the Villapol lab to gain hands-on experience in various lab techniques and to explore her interest in interactions between the brain-gut axis and the progression of Alzheimer’s disease. At Rice, she is on the pre-med track and hopes to specialize in neurosurgery in the future. Outside of research and studying, Savanna loves spending time with her dog and getting coffee with friends.

Maddie Flowers
Medical student
Sam Houston State University
Madelyn earned her Bachelor of Science in Public Health at the University of Texas at Austin in May 2023. She is currently a second-year medical student at Sam Houston State University and has an interest in neurology. As a member of this lab, she hopes to gain more experience in the field of neuroregeneration research and how it intersects with her current studies. In her free time, she enjoys reading and spending time with her family.

Debbie Vu
Program Coordinator
Debbie Vu earned her Masters of Art in Art Leadership from University of Houston in May 2022. She is currently attending University of Houston – Downtown for her Masters of Business Administration. She is currently the Program Coordinator for the Center for Neuroregeneration and Weill Cornell Graduate School – Houston campus. She assist the Center for Neuroregeneration with administrative and educational activities.
