am interested in representation theory and harmonic analysis of Lie
groups. I am also interested in time-frequency analysis (Gabor theory),
frame, sampling, interpolation, and wavelet theories on commutative and
non-commutative domains. Recently, I have been exploring the
connections between theoretical and computational (Computer Algebra
Systems) aspects of representation theory.
