M Mohammed Idris is the senior principal scientist in Center for cellular and molecular Biology (CCMB). He obtained his PhD from Open University, Milton Keynes, United Kingdom. He executed his PhD work at Stazione Zoolgica ‘A.Dohrn’, Naples, Italy and Sven Loven Marine Centre, Gothenburg, Sweden. His major research activity involves understanding the biomechanism of regeneration and degeneration in alternate model systems such as zebrafish (Danio rerio), marine chordates (Ascidians) and echinoderms (Asterias sp). His ongoing work includes Regeneration of appendages in zebrafish, nervous tissue in ascidians and arms in Asterias sp. He is also interested in understanding the molecular and functional mechanism of neurodegeneration due to the triplet repeat expansion as like in spino cerebellar ataxia and Huntington’s disease using zebrafish as the model animal. He published papers on the tissue and organ regeneration in zebrafish, marine chordates and echinoderms and the mechanism of degeneration due to gene, stress and chemicals in zebrafish model system in reputed journals.
