Just as the University of Illinois Urbana-Champaign provided a springboard for Raghu Ganti to enter the workforce, the IBM-Illinois Discovery Accelerator Institute is helping him change the world of foundation models and other uncharted territory.
Ganti received his master's and doctoral degrees in computer science from Illinois. His advisor was computer science professor Tarek Abdelzaher of the Siebel School of Computing and Data Science. Ganti's research focus was on developing an infrastructure toolset for human-centric sensing applications. The systems were designed to make sense of data generated by people and their environments.
When he came to IBM's T.J. Watson Research Center, Ganti found himself working on a project tracking vessels in the Singapore Port using GPS location data. This work showed him what was possible when large-scale data was combined with the right algorithmic lens. In 2014, his team was able to create a model that allowed for the exact time and location to observe an asteroid impact in Hawaii. Fast forward to Ganti's recent work as an IBM Distinguished Engineer. By 2020, the artificial intelligence landscape had already changed--GPUs were now central to research, and the world was now in the era of training large language models.
Changing technology is at the forefront of Ganti's thinking when it comes to how he approaches his research. One of Ganti's proudest accomplishments is his work on the project that became known as Prithvi — the Sanskrit word for "Earth." The project was developed in collaboration with NASA to build Earth observation models from satellite data. The team was first comprised of Ganti and two other researchers before quickly scaling out to include the broader IBM, NASA, and even European Space Agency.
More recently, Ganti has been leading the efforts of bringing up IBM’s new accelerator, Spyre, in the Open-Source community (PyTorch, vLLM) for enabling AI workloads on Z (IBM Mainframes).
Ganti says his career has been a "fun journey" — one that has taken him into a vast array of problems to solve. His career has been defined by consistent curiosity and a desire to explore the uncharted. In a field that moves as fast as artificial intelligence, those are invaluable attributes.
