Subrata Roy is a scientist, inventor, and teacher. He was born in India. He is famous for his work with plasma. Plasma is a special state of matter, like a super-hot gas. Dr. Roy uses plasma to control how air moves (called flow control). He also uses it to create technology that cleans itself. He teaches Mechanical and Aerospace Engineering at the University of Florida. He also started the Applied Physics Research Group there. Dr. Roy is also the founder and president of SurfPlasma Inc., a company that works with biotechnology.

About Subrata Roy
Subrata Roy earned his Ph.D. in engineering science in 1994. He received this degree from the University of Tennessee in Knoxville, Tennessee. After that, he worked as a senior research scientist. He was at Computational Mechanics Corporation in Knoxville.
Roy's Teaching Career
Later, Dr. Roy became a professor of mechanical engineering. He taught at Kettering University until 2006. In 2006, he joined the University of Florida. He became a faculty member in the Department of Mechanical and Aerospace Engineering.
Today, he is a professor there. He also leads the Applied Physics Research Group. Dr. Roy has also been a visiting professor. He taught at the University of Manchester and the Indian Institute of Technology Bombay.
Dr. Roy's Scientific Discoveries
Subrata Roy's research covers many exciting areas. These include computational fluid dynamics (CFD). This field uses computers to study how fluids move. He also studies plasma physics and heat transfer.
Understanding Fluid Flow
In 2003, Dr. Roy added to Knudsen's theory. This theory helps explain how molecules move. It looks at how they bounce off surfaces. His work has been used to study how natural gas flows. This gas is found in shale rock.
Wingless Electromagnetic Air Vehicle
In 2006, Dr. Roy invented something amazing. He created the Wingless Electromagnetic Air Vehicle (WEAV). This vehicle design was featured in Scientific American in 2008. It was the world's first air vehicle designed to fly without wings. It uses electromagnetism to move.
Plasma Actuators and Their Uses
Dr. Roy is well-known for his work with plasma actuators. These devices use plasma to control air flow. He has designed many new types of plasma actuators. They help reduce drag on vehicles, which saves fuel.
They also help make things quieter. Plasma actuators can even cool parts of jet engines. Some of his designs include serpentine and fan-shaped actuators. He also created tiny micro-scale actuators.
Cleaning with Plasma
Dr. Roy has also led research on new ways to clean things. He found eco-friendly methods to remove tiny living things. These methods use plasma reactors to clean surfaces. This helps stop the spread of germs.
Awards and Recognition
Dr. Roy has received many honors for his work. He is recognized by several important organizations.
- Fellow, National Academy of Inventors
- Distinguished Visiting Fellow, Royal Academy of Engineering
- Fellow, Royal Aeronautical Society
- Lifetime Fellow, American Society of Mechanical Engineers
- Space Act Award 2016 NASA
