B. S. Manjunath: From IISc to UC Santa Barbara, an Indian Computer Scientist Building Global Research Impact

The University of California, Santa Barbara’s Distinguished Professor B. S. Manjunath has been selected for the 2026 IISc Distinguished Alumnus Award. His work in computer vision, image retrieval and scientific image informatics illustrates how advanced education in India can contribute to international research and technology.

An Indian Institute of Science graduate who has built an influential academic and research career in the United States is among the distinguished alumni selected for recognition by his former institution.

B. S. Manjunath, Distinguished Professor of Electrical and Computer Engineering at the University of California, Santa Barbara (UCSB), has been named a recipient of the 2026 IISc Distinguished Alumnus Award. The Indian Institute of Science announced the selection on November 6, 2026. The award ceremony is scheduled for December 19 at the J. N. Tata Auditorium on the IISc campus in Bengaluru.

The recognition acknowledges a career spanning computer vision, image and video analysis, multimedia information retrieval and biological image informatics. It also highlights a professional journey linking India’s advanced science and engineering education with research institutions and technology development in the United States.

The IISc foundation

Manjunath completed his Master of Engineering in Systems Science and Automation at IISc in 1987. Before that, he earned a Bachelor of Engineering in Electronics Engineering from Bangalore University in 1985.

He subsequently moved to the United States for doctoral research, completing a PhD in Signal and Image Processing at the University of Southern California in 1991.

His career developed around a problem that has become increasingly important in the digital age: how to organise, analyse and retrieve useful information from enormous collections of images and videos.

As cameras, scientific instruments and digital platforms generate increasingly large volumes of visual data, finding relevant information efficiently is a significant challenge. Manjunath’s research has addressed the mathematical and computational methods that allow computers to identify visual patterns, classify images and retrieve content based on measurable characteristics.

He is now the Frank Koenig Distinguished Chair in Signals and Systems and a Distinguished Professor at UCSB, where his academic affiliations span electrical and computer engineering and computer science.

Research that helped shape image search

One of Manjunath’s significant contributions has been in image and video descriptors: mathematical representations that help computers identify and compare visual content.

His early research helped develop image descriptors that were subsequently incorporated into the ISO/MPEG-7 multimedia content description standard, adopted in 2000. MPEG-7 provides standardised ways of describing multimedia content so that visual and audio information can be indexed and searched.

This work helped advance content-based image retrieval, an approach in which computers search for images using visual characteristics rather than relying only on filenames or manually entered text.

The applications of such research extend across digital libraries, multimedia systems, remote sensing, scientific research and image analysis. UCSB’s account of his work also notes that technologies developed through his research group led to patents and applications in image processing and information security.

Connecting computer vision with biological research

Another important area of Manjunath’s work is scientific image informatics.

Modern biological and medical research increasingly depends on complex visual material, including microscopy images, cellular structures and three-dimensional scientific data. Researchers need tools not only to store these images but also to annotate, analyse, compare and share them in reproducible ways.

Manjunath and his collaborators developed BisQue, an open-source platform for managing and analysing scientific images. It provides researchers with tools to organise image collections, attach metadata, conduct analysis and collaborate around visual datasets.

The platform’s wider relevance is reflected in its adoption within CyVerse, a computational infrastructure supported by the US National Science Foundation for data-intensive science. CyVerse’s documentation identifies BisQue as one of its specialised applications, while UCSB describes its role in managing scientific image data.

This is a useful example of academic research moving beyond journal publications into infrastructure that can support work across scientific disciplines.

Research, entrepreneurship and mentoring

Manjunath’s career has also included technology entrepreneurship. He co-founded Mayachitra, a company focused on computer vision, deep learning, visual search, cybersecurity and digital forensics.

The combination of academic research and commercial development illustrates one route through which university research can be translated into practical technology. It also highlights the importance of collaboration between researchers, students and industry.

Mentoring has been another substantial part of his academic contribution. IISc’s award announcement says he has supervised 53 PhD graduates. His professional distinctions include election as a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), the Association for Computing Machinery (ACM), the National Academy of Inventors and the American Institute for Medical and Biological Engineering.

These recognitions reflect contributions across engineering, computing and the application of technology to biological and medical research.

A wider India–US research connection

Manjunath’s award is more than an individual academic honour. It represents the continuing relationship between India’s research institutions and scientists working in international universities.

For Indian students considering advanced study abroad, his career illustrates how a technical foundation developed at an Indian institution can lead to research leadership in a global academic environment. It also demonstrates that the impact of an overseas academic can extend beyond the university where they work, through open-source platforms, international standards, patents, industry collaborations and the training of future researchers.

That connection should not be overstated: an alumni award does not, by itself, establish a formal research partnership or a new institutional programme between IISc and UCSB. Its significance is the recognition of an alumnus whose career has developed across both academic environments.

The 2026 IISc awards will honour five distinguished alumni, alongside three researchers receiving Young Alumnus/Alumna Medals. The wider group includes scientists and engineers working in condensed-matter physics, defence technology, aerospace engineering, digital infrastructure, theoretical computer science, autonomous systems and biotechnology.

For Manjunath, the December ceremony will bring his international academic achievements back to the institution where his postgraduate journey began. His career offers a clear illustration of how research developed through sustained work in computer science can influence standards, scientific infrastructure and technology applications across borders.
