Ramachary obtained his Masters degree (General Chemistry) at the University of Hyderabad in 1996. There as part of curricula he studied and actively involved in the project, entitled Synthesis and Utilization of Aromatic Radical Anions for Reduction of Carbon Monoxide (with Prof. M. Periasamy).

Ramachary obtained his Doctoral degree (Organic Synthesis) at the Indian Institute of Science, Bangalore for his research work on Total Synthesis of Sesquiterpenes Containing Three Contiguous Quaternary Carbon Atoms (with Prof. A. Srikrishna).

In January 2002, he moved to Prof. Carlos F. Barabas III research group as Skaggs Post Doctoral fellow at The Scripps Research Institute, San Diego. After three year post doctoral studies at TSRI, he then joined as Faculty member in School of Chemistry, University of Hyderabad in Jan 2005, where at present he is a Reader.

Dr Ramachary has been awarded the INSA Medal for Young Scientists in Chemical Sciences for the year 2006 for his outstanding contributions to the emerging area of asymmetric organocatalysis.

The main focus of his research group is to engineer the novel and green asymmetric cascade and multi-component reactions (MCRs) to generate the biologically important molecules and natural products in a single step via emerging chiral amines or amino acid-catalysis.

His research group is actively engaged in the design and synthesis of novel enzyme mimetic small organic amines and amino acids to catalyze the fundamental organic reactions in enantioselective manner.

His interest about inquisitive questions like how small can be highly active and stereo-selective catalysts and what are the minimal functional and structural features required in a chiral catalyst had made him to venture in the most advanced versions of synthetic chemistry.
