Mr Uday K Thapa

I am an environmental scientist and my research focuses on investigating impacts of climate change in forest and hydrology in the Nepal Himalaya. I use the science of dendrochronology to understand variations of climate and hydrology in the Himalaya. My work also involves examining the impacts of climate change in dynamics of Himalayan treeline ecotones. I am equally interested in climate change cross-cutting issues, particularly the role of renewable energy in mitigating GHGs. I am a first year PhD student and my academic adviser is Dr. Scott. St. George. In my PhD dissertation, I am currently working to understand the paleohydrology of the Koshi River watershed in eastern Nepal by establishing a new network of tree ring-width and oxygen isotope records at watershed level.
