Kumar, Praveen was born on September 14, 1982 in Saran, Bihar, India. Son of Jagdish Prasad Roy and Deomati Devi.
- Achievements include research in proposed incontrovertible insights into the problem of Harper-Dorn creep, a 50-years old debate, by producing highly consistent experimental data and a first principle analytical model. Research in ductility-strength paradox and successfully proposed a guideline to achieve higher ductility and higher strength, simultaneously. Research in grain boundary sliding as the dominant deformation mechanism in the ultrafine grained materials being tested under superplastic conditions.
