[9][10] Dhar's research history starts during his graduate studies when he worked on Entamoeba histolytica, the protozoan which causes amoebiasis, focusing on its ribosomal DNA circle.
[7] Later, he studied the human pathogens, Helicobacter pylori and Plasmodium falciparum and their DNA replication and cell cycle regulation.
[15] Dhar has documented his research by way of a number of articles[note 1] and online repositories such as PubMed[16] and Pubfacts have listed many of them.
