Dhevalapally B. Ramachary FTAS, FRSC, FASc, FNASc, also known as D. B. Ramachary (born 1973), is an Indian chemist and professor at the School of Chemistry, University of Hyderabad. He has made numerous contributions in various fields of chemical science.

Early life and education

D. B. Ramachary was born to Shri Ramalingaiahchary and Ramalingamma in 1973, at Thatikal village, Nakrekal mandal, Nalgonda district of Telangana. He did his early schooling at ZPHS schools at Thatikal and Nakrekal, and later joined for an under graduate BSc programme at Nagarjuna Government College (Autonomous) at Nalgonda (1991–1994). Later, he moved to School of Chemistry, University of Hyderabad for pursuing MSc chemistry (1994–96), and then he obtained a PhD in synthetic organic chemistry under the guidance of Prof. A. Srikrishna at Indian Institute of Science in 1996–2001 for the total synthesis of sesquiterpenes. Soon after his PhD in 2001, he moved to US as a Skaggs Postdoctoral Fellow and worked with Carlos F.

Research

In 2005, when Ramachary started his own research career at School of Chemistry, UoH, he showed interest towards discovering green reactions and catalysts. His laboratory mainly focused on the development of organocatalytic sequential one-pot reactions, asymmetric supramolecular catalysis and organocatalysis, development of multi-component and multi-catalysis cascade reactions, and metal-free carbonyls based
