Research

I'm a paleoecologist looking at plant micro-fossils, namely pollen grains and biogenic silica bodies (phytoliths) that accumulate in present-day modern soils and may be found preserved in fossil sediments. I'm interested in understanding the interactions between plants, vegetation and climate, vegetation and climate in the past, pollen and phytolith analyses.

Early in my career, I conducted research on the pollen signal of the forests of the Western Ghats in South India and, more recently, on the palaeo-vegetation of palaeo-anthropological sites in Africa where ancient hominid remains such as bones and stone tools have been found. I also conduct studies on modern soils and plant specimens to understand the possibilities and limitations of these microfossils to reproduce the composition and structure of present-day vegetation, and/or environmental and climatic characteristics.
