Research
I am an applied mathematician interested in “maths that matters”. Especially, I am developing methods of nonlinear time series analysis and applying them to data observed from various nonlinear phenomena. Nonlinear time series analysis provides not only useful information on the underlying dynamics but means of their prediction and control.
So far, I have been developing methods using delay coordinates, recurrence plots, permutations, surrogate tests, symbolic analysis, and point process analysis.
I have also applied these methods to real datasets measured from neurons, brains, heartbeats, winds, solar irradiation, cancers, amoebas, economies, and earthquakes.
Recently, research on recurrence plots has found a new application area in reconstructing three-dimensional chromosome structures for a single cell from experimental Hi-C data.
