research interest is to understand tropical climate change over the
recent centuries using nature's own archives such as corals and
trees. Specifically, my researches aim to understand changes in regional rainfall
variability. The majority of my past and ongoing researches revolve
around corals, from various perspectives and to tackle different
scientific and societal questions. I am also exploring the utility of tree isotopes as a
potential land-based proxy of past rainfall variability in the tropics.
