About Us

The Information Retrieval & Intelligent Semantics (IRIS) Lab in the Department of Information Technology at IIIT Allahabad serves as a focused and dynamic research environment dedicated to addressing cutting-edge challenges in Multilingual, Cross-lingual, and Multimodal Natural Language Processing, Information Retrieval, Computational Biology, Health Informatics, and Artificial Intelligence.


The lab actively explores emerging paradigms such as Generative AI, Agentic AI, and Trustworthy AI, with an emphasis on building robust, scalable, interpretable, and ethically grounded intelligent systems.


The vision of IRIS Lab is to foster inclusive, intelligent, and socially responsible AI technologies that advance fundamental research while delivering meaningful real-world impact. By prioritizing multilingual and cross-lingual intelligence, the lab aims to bridge linguistic and cultural divides, enabling AI systems that are accessible and effective across diverse populations and low-resource settings.


A major thrust of the lab lies in interdisciplinary and application-driven research. In Computational Biology and Health Informatics, IRIS focuses on the fusion of clinical text, biomedical literature, medical images, and biological data to support tasks such as disease prediction, clinical decision support, public health analytics, biomedical knowledge discovery, and precision healthcare.


IRIS fosters a highly collaborative research culture, bringing together faculty members, researchers, doctoral scholars, and students to address complex real-world problems at the intersection of AI, language, and data. The lab actively promotes open research practices, high-quality publications, open-source contributions, and technology transfer through national and international collaborations with academia, industry, and government agencies.
