I hold a degree in Physics from Belmont University, where I delved into the intricacies of the universe. With a passion for unraveling its mysteries, I guide students through the wonders of physics, igniting curiosity and understanding. My journey through academia has equipped me with a deep understanding of various subjects beyond physics, ensuring a comprehensive approach to education. From classical mechanics to quantum theory, I strive to make complex concepts accessible and engaging. Let's embark on a journey of discovery together, where questions are welcomed, and knowledge knows no bounds.
