Dr. Lekhendra Tripathee is an Assistant Professor at the State Key Laboratory of Cryospheric Science, Chinese Academy of Sciences who focuses his research on atmospheric sciences. His research involves analyses of different compartments of environment and atmosphere such as precipitation and aerosol chemistry, fresh water chemistry (rivers and lakes) and soil physicochemical characteristics. He has done a field work up to the elevation of 5500 meters above sea level. His keen focus is to observe mercury (Hg), trace elements, major ions composition in air, water and soil and relate those pollutants in the environment with health of the ecosystems. Moreover, he investigates these pollutants in the sediments, water, snow-ice and soil from high altitude regions. 

Analyses of pollutants in the air, water and soil gives information on concentrations, sources and variations of those pollutants in the environmental systems and these could be bioaccumulated in the ecosystems in the urban as well as in the remote pristine areas which have a serious impact on the whole ecosystem and human health. This helps scientists to find out the dynamics of these pollutants in the different compartment of the environment. 

He started doing research in this field when he started his PhD research at Institute of Tibetan Plateau Research, Chinese Academy of Science since 2012.
