Dr. Bigyan Neupane

PhD Physical Geography from Northwest Institute of EcoEnvironment and Resources, Chinese Academy of Sciences (NIEER, CAS), Lanzhou, China

After the successful completion of undergraduate from Kathmandu University in Environmental Science (Honours) and postgraduate from Pokhara University in Environment Management, Dr. Bigyan Neupane graduated as a doctorate in Physical Geography from Northwest Institute of EcoEnvironment and Resources, Chinese Academy of Sciences (NIEER, CAS), Lanzhou, China. During Ph.D., his research was focused on environmental change and paleoenvironmental reconstruction of historical black carbon (BC) from the lake sediments of the Himalayan-Tibetan Plateau. After doctorate, Dr. Bigyan joined Fudan University, Shanghai for one year as a postdoctoral researcher and currently he is serving as a Distinguished Associate Researcher at South China Normal University – School of Geography, Guangzhou, China. Dr. Bigyan has published several high impact factor scientific papers in reputed international peer reviewed journals contributing in this field of environment. He has also participated/presented in various conferences and talk programs related to the environment and human health risks arising from environmental pollution.

Dr. Bigyan has served as an Environmental Officer and Portfolio Manager at Poverty Alleviation Fund Nepal (PAF Nepal), an autonomous body of Government of Nepal under the Prime Minister’s Office. As a beginner in his professional years, he also served for environmental consultancies in conducting EIA and environmental monitoring.

Dr. Bigyan is a keen learner in environmental science and focuses on Environmental Change. Also, he has hands-on experiences in the laboratory equipment such as Desert Research Institute and Sunset Carbon Analyzer, among others. He is a recipient of Excellent International Ph.D. Graduate 2020, University of Chinese Academy of Sciences.


Research Area

  • Environmental change
  • Paleoenvironment reconstruction
  • Black carbon in sediments and peatlands
  • Environmental information
  • Combustion-derived pollutants

Black carbon (BC) and sediments:

BC is a kind of specific carbonaceous aerosols produced during incomplete combustion of fossil fuel and biomass. It is considered to be a driver of global warming in recent years, which not only absorb solar radiation in contributing to the atmospheric warming but also accelerate the glacier melting process. BC has been globally distributed and evident in sediments, soils and glaciers where atmospheric transport is the main route for an increase of contaminants loading and precipitation removes atmospheric pollutants and subsequently deposits in the sediments and other environmental settings. Therefore, sediments serve as one of the archives to study long-term environmental changes, past climate and depositional history of various chemical constituents and combustion-derived pollutants.
