Bhushan began his education in his native India, completing his undergraduate degree and his master's from the University of Jodhpur.

He received his Ph.D. in chemistry (working on structure elucidation of natural products isolated from certain desert plants) in 1978 at the University of Jodhpur.

At Washington State University he established early steps in metabolism of d-neomethyl-α-D-glucoside in pipermint (Mentha piperita) rhizomes via in vivo studies.

Bhushan developed a de novo method for direct resolution of certain racemates by liquid chromatography.

[1] The method is of significant importance to pharmaceutical industry and analytical laboratories associated with regulatory agencies for determination and control of enantiomeric purity (and isolation of native enantiomers) of a variety of APIs since many of them are marketed and administered as racemic mixture while only one enantiomer is therapeutically useful.
