Research Interests

Dr. L. B. Chaudhary is actively engaged in his research activities since last 31 years on plant taxonomy and biodiversity. He started his research career at Botanical Survey of India, Kolkata in ‘Flora of India’ project under the supervision of Dr. M. Sanjappa, ex-Director, BSI, Kolkata. Dr. Chaudhary obtained his Ph. D. degree from University of Kalyani, Kalyani, W. Bengal on the topic “Taxonomic revision of tribes Theropsideae, Genisteae, Trifolieae and Loteae (Leguminosae – Papilionoideae) of India”. Presently, he is working as a Senior Principal Scientist at CSIR-National Botanical Research Institute, Lucknow, where recently he has also revised taxonomically most difficult genera  Astragalus and Oxytropis of the family Leguminosae. Apart from legumes, Dr. Chaudhary has also worked out the taxonomy and diversity of Tricholepis (Asteraceae) and three highly medicinally important plant genera Aconitum (Rananculaceae), Podophyllum (Podophyllaceae) and Phyllanthus (Phyllanthaceae). So far, 12 new species/taxa (Astragalussanjappae Chaudhary & Khan, Astraglus uttaranchalensis Chaudhary & Khan, Astragalus lachungensis Chaudhary, Astragalus nainitalensis Chaudhary, Astragalus himachalensis Chaudhary & Rana, Astragalus gooraiensis Chaudhary,  Trifoliae subtrib. Parochetinae Chaudhary & Sanjappa, Aconitum heterophyllum var. roylei Chaudhary & Rao, Phyllanthus ajmerianus Chaudhary & Rao, Tricholepis raghavendrae Saklani & Chaudhary,Oxytropis zemuensis (Smith) Chaudhary, Oxytropis sanjappae Chaudhary) to the science and many new records for India, Nepal and Myanmar have been discovered by him.  He has also made several new combinations and synonyms in different genera, other than solving many taxonomic problems in various groups. In addition to revisionary studies, Dr. Chaudhary has also carried out floristic investigation of Bhimbetka forest, Madhya Pradesh, Sonbhadra district, Uttar Pradesh and  Dima Hasao district, Assam.


Till date more than 100 research papers published in different journals of national and international repute and three research books are in his credit. He has also contributed materials for ‘Flora of India’ (legume volume) on Astragalus, Oxytropis and its related groups. Dr. Chaudhary has completed nearly two dozen research projects on various aspects of taxonomy funded by CSIR, DST, DBT, MOEF&CC etc.  Being a good plant explorer, he has collected large number of plant specimens from throughout the Himalaya and also other parts of the country. On official visit, he has also travelled abroad like London (Kew), U. S. A. (New York), Mexico (Mexico City) and Nepal (Kathmandu) for herbarium study and participating planning meeting on DNA barcode. Dr. Chaudhary has been awarded Dr. S. K. Jain medal in 2008 by Association for Plant Taxonomy (APT) Dehra Dun for his significant contributions and promoting angiosperm taxonomy. Six students have been awarded Ph. D. degree under his able supervision and guidance and presently 10 students are working with him on various taxonomic aspects.  Currently, Dr. Chaudhary is looking after the herbarium of CSIR-NBRI, Lucknow (LWG) for its maintenance and curation apart from other research activities.
