CURRENT PROJECT: Era.Net RUS Plus (01.01.2016 - p/t). 

I am applying state -of- the-art methods of dendrochronology, stable carbon and oxygen isotope analyses, and climate modeling to reconstruct temperature and precipitation anomalies, and provide detailed predictions of climatic disturbances induced by major Common Era volcanic eruptions and their impact on socio-economic systems in key regions of the Northern Hemisphere with varying degrees of resilience.
