Biography
Dr. Ravi Bathe is a Scientist - G and the Head of the Centre for Laser Processing of Materials at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) in Hyderabad, India. Dr. Bathe obtained his M.Sc. and Ph.D. degrees in physics from the University of Pune in 1995 and 2000, respectively. His Ph.D. study focused on the impact of dopants and defects on the properties of colossal magnetoresistance manganite systems. Following the completion of his studies, he pursued postdoctoral research at the University of Maryland, USA (2000-2002) to investigate wide-band gap semiconductor thin film fabrication using pulsed laser deposition and sputtering.
Dr. Bathe began his career as a Research Scientist in the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI), in 2003. He has been involved in various laser processing of materials technology development, such as laser drilling of aero-engine components, laser surface texturing of automotive components, laser welding, laser micro/nano machining, laser surface engineering, and additive manufacturing. Under his leadership, the Centre for Laser Processing of Materials developed a range of applications for automotive, power, aerospace, electronics, nuclear and other sectors and also provided expert help to several other organizations.
In 2009-2010, Dr. Bathe worked as a visiting scientist at Harvard University, exploring the use of femtosecond lasers for microfabrication, optical hyperdoping and black silicon. Dr. Bathe has presented his research findings at many international and domestic conferences and seminars. His work has been published in numerous high-impact journals and is regularly cited by other researchers in the field. He is the author of more than 110 research papers, five patents and four book chapters, and has also guided several graduate theses at both the Masters and Ph.D. levels.
In recognition of his outstanding contributions, Dr. Bathe was awarded the Fast Track - Young Scientist Award by the DST in 2003 and the Indo-US Research Fellowship by the Indo-US Science and Technology Forum in 2009. He has played a key role in advancing the field of laser processing of materials and its application in industry, and his work continues to shape the future of the industry.
