About Me
My academic journey began with an enduring fascination for synaptic plasticity and its central role in learning, memory, and neurological disease. This early curiosity matured into a focused research interest in the molecular and cellular mechanisms driving neurodevelopmental disorders. As a PhD student in the Integrated Biomedical Sciences program at UT Health San Antonio, I am currently investigating the role of microglial Fmr1 in synaptic pruning and circuit maturation in Fragile X syndrome. My research integrates genetic manipulation techniques—including CRISPR/Cas9—with cellular, molecular, and behavioral analyses to uncover mechanisms of impaired synaptic pruning. Because synaptic pruning is a critical process underlying experience-dependent plasticity, disruptions in this process may directly impair long-term circuit refinement and plasticity. I am also exploring non-viral gene editing as a therapeutic strategy, with an emphasis on improving delivery efficiency, minimizing immunogenicity, and enhancing cell-type specificity for translational application in neurodevelopmental disorders. Through this work, I aim to contribute to the development of targeted interventions for neurodevelopmental disorders and build a research career focused on gene-based modulation of brain function.
Hobbies/Interests
I enjoy outdoor sports, particularly cricket and football (soccer), which keep me active and engaged in teamwork. I also love traveling to experience natural beauty, especially spending time at the beach where I can relax and appreciate the ocean’s tranquility. These activities provide a refreshing balance to my academic pursuits and inspire a sense of calm and creativity.
