Dr. Takahashi has extensive research experience in the field of magnetospheric ULF waves. He has published numerous papers on ULF waves observed by satellites including ATS, ISEE, AMPTE/CCE, CRRES, SCATHA, GOES, Geotail, THEMIS, and  Van Allen Probes.  Results reported in these papers include: multiharmonic toroidal waves; field line mode structure of compressional Pc5 waves and giant pulsations; cavity mode Pi2 waves; solar cycle variation of plasma mass density; and energy and pitch angle dependence of ion flux oscillations induced by standing Alfvén waves. Dr. Takahashi has contributed to the magnetospheric physics community as a convener of meetings and sessions; as a IAGA reporter on ULF waves; by serving on review panels; as a Co-chair of the new NSF GEM Focus Group on ULF waves. He is a member of the project scientists team for the Van Allen Probes and Parker Solar Probe missions.
