In Memory of Dr. Lalit Bahl
The Cancer Center at Illinois (CCIL) community is deeply saddened by the passing of distinguished alumnus of The Grainger College of Engineering at the University of Illinois Urbana-Champaign Dr. Lalit Rai Bahl, who died on August 24, 2025, at age 82.
“Dr. Bahl and Mrs. Kavita Kinra are among the Cancer Center at Illinois’ earliest and most ardent supporters,” said CCIL Director Rohit Bhargava. “He consistently emphasized the need to make advances against cancer that directly improve outcomes. We will remember Dr. Bahl not only for his scientific achievements but also for his generosity of spirit, mentorship, and the inspiration he provided to many.”
A communications and information theory pioneer, Bahl leaves an enduring research legacy, including developing methods and algorithms adopted by nearly every speech recognition research team globally. Over the course of his career, Bahl published more than 80 technical papers in prominent scientific journals and conferences, received 37 U.S. patents and published 114 inventions in the IBM Technical Disclosure Bulletin.
“In addition to his life-changing scientific discoveries and innovations, Dr. Bahl was a dedicated supporter of the University of Illinois and its students,” said Dean of The Grainger College of Engineering Rashid Bashir. “With a deep sense of gratitude for his education and the support he received at the University of Illinois, Dr. Bahl was extraordinarily generous with gifts that directly impacted the student experience.”
His numerous contributions to the university have impacted Illinois scholarship and education excellence at the CCIL and The Grainger College of Engineering, including creating the Joan and Lalit Bahl Fellowship in Electrical and Computer Engineering (ECE) and the Ravindar K. and Kavita Kinra Fellowship in Civil and Environmental Engineering, and supporting the Civil and Environmental Modernization Project and construction of the new ECE building.
The Bahl family funded the construction of a beloved engineering campus landmark, the Kavita and Lalit Bahl Smart Bridge. Traversed by hundreds of students daily, the 2,000 square foot suspension bridge serves as a living laboratory, collaborative and comfortable gathering space for students, event location and a walkway.
Lalit is survived by his wife, Kavita; his children, Krishna Bahl, Kiran Bahl, Ashok Bahl (Mary Przywara), Anjali Vij (Mohit) and Rajeev Kinra (Sonia); and his grandchildren, Lily and Ashler Bahl, Raveena and Devyani Vij, and Anand, Siddharth, and Meenakshi Kinra.
“We extend our heartfelt condolences to his family, friends and all who were fortunate to know him. His legacy will live on through the lives he touched and the work he leaves behind,” said Bhargava.
