Research Interests

Takeshi Nakagawa’s research interests include Quaternary palaeoclimatology, pollen-based quantitative climate reconstruction, climatic tele-connection, abrupt climate changes, role of solar forcing and monsoon front in the regional variety of climate changes.

Current Work

Takeshi Nakagawa is currently PI on two NERC-funded projects, one looking at pan-hemispheric synchrony/asynchrony of D/O events and the other using radiocarbon-based information to establish a new calibration model for the Late Pleistocene (10,000-50,000 yr BP). The latter information will be used to determine the timing and rates of environmental changes, as well as understanding past changes in the global carbon cycle. Both these projects are using material from the ultra-high resolution varved (annually laminated) sequence from Lake Suigetsu, Japan.
