Research Interests:

Radio observations and theoretical (analytical and numerical) studies in pulsar astrophysics.

• Theoretical: structure of pulsar magnetosphere; plasma processes for radio emission; electrodynamics and the effects in super-strong magnetic field; radio emission variability as revealed by single pulses and the averaged pulse profiles.
• Observational: Averaged pulse profiles and diversities in radio single pulse emission; monitoring radio frequency interference (RFI) for improving on the sensitivity and quality of pulsar data.
• Computational: pulsar emission geometry; structure of the magnetic field in pulsar magnetospheres; numerical analysis and simulations.
