Prof Manna is a metallurgical engineer, a renowned educator and a prolific researcher. His significant contributions in the studies of amorphous/nanocrystalline Al-alloys, nano-fluid and laser/plasma assisted surface engineering greatly inspired the scientific community. His early contributions in moving boundary phase transformation are still widely cited. As a teacher, Prof Manna has developed several new courses and taught subjects related to phase transformation, materials engineering, surface engineering, thermodynamics and X-ray diffraction. His research interest spans from structure-property correlation in engineering materials including synthesis/application of nano-materials, surface coating/engineering, phase transition, fuel cells, sensors, bainitic steel and mathematical modeling.
Prof Manna worked as guest scientist in several institutions of excellence and universities abroad such as Max Planck Institute at Stuttgart, Technical University of Clausthal, Nanyang Technological University, Liverpool University, University of Ulm, etc.
Prof. Manna is a recipient of INSA Medal for Young Scientists, Young Metallurgist and Metallurgist of the Year Awards, MRSI Medal, AICTE career award, DAAD and the prestigious Humboldt Fellowships. He is also a recipient of the Acta Materialia Best Referee Award for years 1999 and 2003, respectively. The German Academic Exchange Service (DAAD), Bonn appointed Prof Manna as Honorary DAAD Advisor in India for three years, INAE selected him for Indian National Academy of Engineering-All India Council of Technical Education (INAE-AICTE) Distinguished Industry Professorship for 2007-08 to work with Tata Steel, and the Indian Institute of Metals (IIM) conferred upon him the GD Birla Gold Medal for 2008.
He has published about 225 peer-reviewed papers, supervised 14 Ph.D, 35 M. Tech. and 50 B. Tech. theses, carried out 32 sponsored projects worth over Rs. 16 crore and also obtained a patent on amorphous AlCuTi alloy.
Prof. Manna is a Fellow (FNAE) of the Indian National Academy of Engineering, New Delhi; a Fellow (FNASc) of The National Academy of Sciences of India, Allahabad; and a Fellow (FASc) of the Indian Academy of Sciences, Bangalore.
Prof. Manna was the President of the Materials Science Section of the 97th Indian Science Congress held in Trivandrum during January 3 - 7, 2010. The INAE has recently awarded him the prestigious "INAE Chair" for two years. To date, he remains the third recipient of this prestigious chair.
