New Delhi, 2025 Dr. Gurtej Singh Sandhu, an Indian-origin engineer and scientist, is one of the most brilliant minds in modern technology. His inventions power almost every digital device used today, yet his name is not widely known.
The Power Behind Modern Chips
Dr. Sandhu works at Micron Technology, one of the world’s largest memory chip companies. He holds more than 1,380 patents in the United States, which is more than Thomas Edison, the famous inventor of the light bulb, who held 1,093 patents.
His work focuses on how to make microchips smaller, faster, and more efficient. These chips are the tiny parts that store and process data inside mobile phones, computers, and cloud servers.
Education and Early Life
Dr. Sandhu studied Electrical Engineering at IIT Delhi, completing his MTech in 1985. Later, he earned his PhD in Physics from the University of North Carolina, USA, in 1990. His strong knowledge of both engineering and physics helped him solve complex problems in semiconductor design.
