Qudsia Tahseen (born 15 December 1964) is a Professor of Zoology at Aligarh Muslim University and teaches Animal Ecology as well as Nematology to the students of the Masters programme. Her areas of research include taxonomy and developmental biology of terrestrial and aquatic nematodes. Her thrust areas are Biodiversity, Taxonomy, Ecology and developmental biology of soil and fresh water nematodes. She is a fellow of two national science academies of India. Education Qudsia Tahseen's schooling was from Azamgarh. From there, she moved on to pursue higher education in Zoology from Aligarh Muslim University. She completed her M.Sc. in Zoology in the year 1984 and was awarded a Gold Medal. She also pursued Diploma in Statistics. She joined research in the Department of Zoology and completed her M.Phil in 1987 and Ph.D in 1989. Career Qudsia Tahseen's first appointment as a faculty was in 1989 in Women's College AMU even before she had received the PhD degree. In 1997, she got transferred to the Department of Zoology, Aligarh Muslim University first serving as a Reader and then a full Professor. Research She has been carrying out numerous studies on taxonomy, biodiversity, and biology of soil and aquatic nematodes resulting in discovery and description of several new species of Nematodes from India. Most recently her group discovered an intermediate species between two different genera of Nematodes. In view of the scarcity of reports on these groups from India, she undertook the challenging task of exploring Indian habitats and made critical observations on the structure and morphology of free-living nematodes using LM and SEM. She has described and revised a good number of nematode taxa and has addressed the taxonomic identification from different perspectives so as to adopt a holistic approach combining morphological, developmental and ecological characteristics for better scientific value instead of the lopsided shallow morphological study. Her lucid and critical analyses of species supplemented with Scanning Electron Microscopic details were commended by peers and her wide taxonomic skills have been accredited internationally as she remains so far the only Asian to receive ONTA Special Award for sustained excellence in Nematology. She has also conducted pioneering studies in India on nematode development while her ecological findings led to the understanding of shifts in subterranean food web. Due to the skills and expertise, she has been invited to labs of Europe and America under fellowships of Royal Society, Rothamsted International, INSA, DBT, TWAS,
