About
Howdy! I’m Ajitha, a graduate student in the Department of Physics. This is my fourth year mentoring in the DEEP program. My primary research focuses on experimental quantum physics, magneto-sensing applications, and ultrafast pulse lasers for inertial fusion. I’m passionate about exploring new and challenging areas of knowledge, and DEEP has been the perfect platform for this, surrounded by enthusiastic colleagues and students.
I’m also an active member of the Aggie Magic Circle, where I combine my fascination with quantum science and the art of magic—an exciting blend of creativity and science. When I’m not immersed in research, I enjoy playing guitar and tabla, indulging in music as a refreshing break from the world of science.
