completed my certificate course in general forestry in Bhutan Forestry Institute, Taba in the year 1996. From 1997 to 1999, I worked for forest territorial division under Mongar and Trashigang, and later under Bumdeling Wildlife Sanctuary, Trashiyangtse. From 2010 onwards, I joined Ugyen Wangchuck Institute for Conservation and Environmental Research in Lamai Goempa, Bumthang, where I focused more on research in Water and Conservation Biology departments.
Beside my regular activities, I conducted research on the butterflies and moths taxonomy, which include training of tourist guides and drop-out student. Remarkably, I rediscovered Ludlowi Bhutan Swallowtail (Bhutanitis ludlowi) from Tobrang, Trashiyangtse, after 78 years, in 2009 and also discovered new plume moth to science Pterophorus karmawangdii. I also author field guides such as Swallowtails of Bhutan, Nymphalids of Bhutan, Hesperiidae of Bhutan, Pierids & Lycaenidae of Bhutan, Checklist of Bhutan butterflies and also hot spring and minerals of Bhutan, Butterflies of Trashiyangtse valley. From 2014 onwards, I started to work on the moths of Bhutan in collaboration with National Biodiversity Centre in Bhutan and Naturalist Biodiversity Centre in the Netherlands, which resulted in publication of numerous journal papers, posters and brochures of Butterflies & Moths.
