Undergraduate: Mathematics I
Presently working in the area of analysis and modeling of naturally occurring series from Ionospheric and Magnetospheric data. Investigated the chaotic dynamics of the time series of Total Electron Content (TEC), the geomagnetic horizontal Intensity (H) and the RING current index (Dst). The analysis based on the calculation of the invariant characteristics such as Lyapunov exponent, Correlation dimension, etc. and of the surrogate data test established the existence of a low dimensional deterministic chaotic system in all cases. Both the dynamics are efficiently modeled to an approximate functional relation in symbolic form using an evolutionary program. Continuing the analysis in the case of the Dst data also. The Wavelet analysis of these data sets is in progress. 3 papers are communicated to internationally reputed journals. Two of them are under revision
