Amazon and IIT Bombay (IIT-B) today announced the inaugural award recipients of the Amazon IIT–Bombay AI-ML Initiative. The awards recognize researchers whose work fulfills the goals of the initiative: to advance artificial intelligence and machine learning research within the speech, language, and multimodal-AI domains.

The Amazon-funded collaboration, launched in March 2023 and housed in the IIT Bombay Department of Computer Science and Engineering, aims to promote partnership among faculty and leading scholars and foster a diverse and sustainable pipeline of research talent.

In line with the goals of the initiative, the award winners are conducting research in multiple domains including large language models (LLMs), machine learning, federated learning, and natural-language processing (NLP).

"We are pleased to witness the unfolding of this relationship and the significant potential it embodies,” said Sachin Patwardhan, dean of research and development at IIT Bombay. “The selection of nine project proposals under the Amazon IIT-B AI-ML Initiative further accentuates our shared commitment to advancing knowledge and innovation."

The research award provides selected professors at IIT Bombay with up to one full year of funding to pursue independent research projects. The nine research projects selected will be run by IIT Bombay faculty and researchers.

“We are excited about the progress we have made with our partnership with IIT-B,” said Snehal Meshram, senior manager of product management technology with Alexa. “Through the diverse project proposals, we have ensured investments in key research areas that will mutually benefit Amazon and IIT-B. This is just the beginning of what we anticipate to be a long and fruitful collaboration.”

The winners of the awards are as follows:

Pushpak Bhattacharyya, professor of computer science and engineering, and Preethi Jyothi, associate professor of computer science and engineering

Bhattacharyya and Jyothi’s research revolves around speech-to-speech machine translation with a focus on Indian languages. They intend to develop a multilingual and multimodal pretrained model for Indian languages and specific linguistic phenomena seen in India (such as disfluency and code mixing). The goal is a model that demonstrates effectiveness in a speech-to-speech translation system, while the project will also release curated training data specific to the Indian use case.

Abir De, assistant professor of computer science and engineering, and Soumen Chakrabarti, professor of computer science and engineering

De and Chakrabarti’s research focuses on multimodal representation, retrieval, and transformation using graph-structured objects. The proposal aims to develop methods for information retrieval on a large corpus of graphs, which should allow for multimodal retrieval (text and images).

Avishek Ghosh, assistant professor, systems and control engineering, and Swaprava Nath, assistant professor of computer science and engineering

Ghosh and Nath’s proposal aims to leverage game-theoretic constructs to incentivize contributions from users in federated learning, where a large number of users submit locally computed results that are merged in a centralized server.

Preethi Jyothi, associate professor of computer science and engineering

Jyothi’s proposal aims to build techniques that will make cross-lingual transfer more efficient and effective, using both automatic-speech-recognition (ASR) and NLP pretrained models.

Ankur A. Kulkarni, associate professor of systems control and engineering

Kulkarni’s proposal aims to develop game-theoretic mechanisms for strategic classification, such as when inputs to a machine learning model have been purposefully altered during testing time.

Ajit Rajwade, associate professor of computer science and engineering

Rajwade’s research will examine nearest-neighbor search in large datasets via group testing. By combining multiple samples in a particular way, the research will determine whether fewer tests are needed.

Ganesh Ramakrishnan, professor, computer science and engineering, and Kshitij Jadhav, assistant professor, Koita Centre for Digital Health

Ramakrishnan and Jadhav’s research will apply LLMs in the healthcare domain and explore both explainability and verifiability. Their work will incorporate domain-specific training, retrieval augmentation, and alignment to feedback from healthcare experts.

Sunita Sarawagi, professor, computer science and engineering

Sarawigi’s research will explore the integration of LLMs with structured databases. Her proposal aims to investigate a series of problems, including converting text to SQL, the continuous improvement of LLMs, and relating trends in structured data to real-world events, and to provide these capabilities in custom LLMs that are developed over private data.

Virendra Singh, professor, department of electrical engineering

Singh’s research will use natural language to align reinforcement learning (RL) agents toward human-like behavior. His proposal aims to develop techniques to make RL more sample efficient, using auxiliary NLP tasks such as providing textual descriptions of the actions taken by RL agents.

At Amazon Selection and Catalog Systems (ASCS), our mission is to power the online buying experience for customers worldwide so they can find, discover, and buy any product they want. We innovate on behalf of our customers to ensure uniqueness and consistency of product identity and to infer relationships between products in Amazon Catalog to drive the selection gateway for the search and browse experiences on the website. We're solving a fundamental AI challenge: establishing product identity and relationships at unprecedented scale. Using Generative AI, Visual Language Models (VLMs), and multimodal reasoning, we determine what makes each product unique and how products relate to one another across Amazon's catalog. The scale is staggering: billions of products, petabytes of multimodal data, millions of sellers, dozens of languages, and infinite product diversity—from electronics to groceries to digital content. The research challenges are immense. GenAI and VLMs hold transformative promise for catalog understanding, but we operate where traditional methods fail: ambiguous problem spaces, incomplete and noisy data, inherent uncertainty, reasoning across both images and textual data, and explaining decisions at scale. Establishing product identities and groupings requires sophisticated models that reason across text, images, and structured data—while maintaining accuracy and trust for high-stakes business decisions affecting millions of customers daily. Amazon's Item and Relationship Platform group is looking for an innovative and customer-focused applied scientist to help us make the world's best product catalog even better. In this role, you will partner with technology and business leaders to build new state-of-the-art algorithms, models, and services to infer product-to-product relationships that matter to our customers. You will pioneer advanced GenAI solutions that power next-generation agentic shopping experiences, working in a collaborative environment where you can experiment with massive data from the world's largest product catalog, tackle problems at the frontier of AI research, rapidly implement and deploy your algorithmic ideas at scale, across millions of customers. Key job responsibilities Key job responsibilities include: * Formulate novel research problems at the intersection of GenAI, multimodal learning, and large-scale information retrieval—translating ambiguous business challenges into tractable scientific frameworks * Design and implement leading models leveraging VLMs, foundation models, and agentic architectures to solve product identity, relationship inference, and catalog understanding at billion-product scale * Pioneer explainable AI methodologies that balance model performance with scalability requirements for production systems impacting millions of daily customer decisions * Design and execute model distillation strategies—distilling large frontier LLMs and VLMs into compact, production-grade models—that preserve multimodal reasoning capability while dramatically reducing serving latency, cost, and infrastructure footprint at billion-product catalog scale * Own end-to-end ML pipelines from research ideation to production deployment—processing petabytes of multimodal data with rigorous evaluation frameworks * Define research roadmaps aligned with business priorities, balancing foundational research with incremental product improvements * Mentor peer scientists and engineers on advanced ML techniques, experimental design, and scientific rigor—building organizational capability in GenAI and multimodal AI * Represent the team in the broader science community—publishing findings, delivering tech talks, and staying at the forefront of GenAI, VLM, and agentic system research
