Niranjan Parajuli (Nepali: निरञ्जन पराजुली) is a Nepali chemist, biochemist and biotechnologist, who was President of Nepal Chemical Society (2019-2021)[1] and served as Professor of Chemistry at the Central Department of Chemistry, Tribhuvan University, Nepal from March 2018 to January 2025.[2][3] Parajuli recently resigned from Tribuvan university.[4] He has advocated for change in the Nepali education system, writing op-eds for national dailies, particularly focusing on higher education.[5] EduRank has sorted Professor Parajuli as a notable alumnus of Tribhuvan University.[6]

Personal life

Niranjan Parajuli was born in Kathmandu, the capital of Nepal to Govinda Prasad Parajuli (Nepali: गोविन्द प्रसाद पराजुली) and his wife Durga Parajuli (Nepali: दुर्गा पराजुली), in August 1972. He is married to Madhabi Bhatta who is a Nepali journalist and former commissioner of the Truth and Reconciliation Commission, Nepal.[7]

Religious views

In an interview by a Nepali Science Magazine, RevoScience dating to 2016, Parajuli has clarified that he believes in religion however is secular, he has added that he is not able to lead religion, because there are certain things which even science is unable to clarify.[7]

Public affairs

Parajuli has been voicing a topic related to compensation in land procurement in Tinkune, Kathmandu because he is also one of the land owners who did not receive compensation for land acquisition from the government of Nepal for about 50 years.[8][9]

Education

Parajuli has received his Bachelor of Science majoring in Physics, Chemistry, and Mathematics from Tribhuvan University in 1994. He then completed his Master of Science degree majoring in Chemistry from the same university with the highest honors in the whole graduate program.[7] Parajuli received his doctorate in biochemistry from the Department of Chemistry, Institute of Biomolecule Reconstruction at Sun Moon University, Korea in 2004. His PhD dissertation focuses on manipulation of antibiotic biosynthetic pathway and bioorganic chemistry.[10]

Career and research

Parajuli began his career at Kathmandu University as a lecturer of Chemistry in 1998. He was promoted to assistant professor at the same institution in 2004. He was a postdoctoral researcher from 2005 to 2009 at Ewha Womans University, Seoul, Republic of Korea upon completion of PhD from Sun Moon University. He assumed the role of a research professor at the same university in 2009. From early 2010 to late 2011 he was a postdoctoral research associate at the Department of Chemistry at North Carolina State University, Raleigh, USA. As a biotechnologist, from 2012 he led the Department of Biotechnology, National College, Tribhuvan University, as the head.

Teaching

Parajuli started his teaching career from Kathmandu University in 1998, continuing teaching activities from other institutions after leaving Kathmandu University, he has been appointed as a teaching full professor in 2018 at Tribhuvan University.[2] His area of teaching is organic chemistry and biochemistry. He is famous among students through his teaching and research. Five Ph.D. candidates and dozens of graduate students did their theses under the supervision of Parajuli at Tribhuvan University.

Research

Parajuli's research is mostly focused on microbial biotechnology, enzyme technology, protein engineering and combinatorial chemistry.[2] He is also active in research using applied biophysics in the field of biochemistry and computational chemistry.[11] He has also published his research works in the field of nanotechnology, from a biological point of view.[12] In 2009, he was appointed as a research full professor. As of 2020, Parajuli has projects in the fields of computational chemistry, identification of enzyme inhibitors from plant sources to treat diabetes, and genetic characterization of actinomycetes for antibiotics production.[13] He also is the chief scientific advisor to a project on investigation of secondary metabolites from natural products with a computational chemistry and immunochemistry approach on COVID-19.[14] He was one of the top scientists in Nepal to receive huge research grants from the University Grants Commission of Nepal between 2019 to 2024. He was employed as a South Korean government-sponsored invited scientist (Research Professor) at Sun Moon University, Korea between 2023 to 2024.[15] He has contributed more than 80 articles in peer-reviewed journals.[16]
