He has discovered over a dozen new species including new anglerfishes and cavefishes.
The LSU Museum of Natural Science fish collection that Chakrabarty oversees includes nearly half a million fish specimens and nearly 10,000 DNA samples covering most major groups of fishes. He earned his PhD at the University of Michigan and his undergraduate degree is from McGill University in Montreal. He has written two books including A Guide to Academia: Getting into and Surviving Grad School, Postdocs and a Research Job. He is also a former Program Director at the National Science Foundation.
