Hi, I'm Rabeetha, a researcher specializing in frame theory, sampling theory, wavelet analysis. My Ph.D. thesis focused on studying twisted shift-invariant spaces using group Fourier transform on the Heisenberg group, which is a simple example of a non-abelian locally compact group. I have also worked on graph signal processing, and I am excited to continue exploring how signals on graphs can be sampled, analyzed, and reconstructed. 

Alongside my research, I am an educator with a deep passion for teaching. I mentor students in developing problem-solving skills and a deeper understanding of mathematical concepts. I believe in shifting from teacher led instruction to student driven learning, encouraging students to think independently, solve problems creatively, and face challenges with confidence. Through hands-on activities and an engaging classroom environment, I aim to spark curiosity, encourage critical thinking, and inspire a lifelong love for mathematics in every student I teach.
