Professor Saha’s research bridges public health data science, computational epidemiology, and biomedical informatics, with a primary focus on cancer. He brings together methods from artificial intelligence, digital pathology, radiology, genomics, and electronic health record research to study how disease develops, progresses, and can be detected and prevented at the population level.
Professor Saha was a Research Fellow in the Division of Cancer Epidemiology and Genetics (DCEG) at the National Cancer Institute (NCI), National Institutes of Health (NIH), USA, one of the world’s foremost cancer research centres. Earlier, he held the position of Research Scientist in the Department of Biomedical Informatics at Emory University, USA. Across these positions, he worked in epidemiology, pathology, radiology, medical imaging, genomics, and health data science.
Professor Saha completed his PhD in Medical Science and Technology from the Indian Institute of Technology (IIT) Kharagpur, where his doctoral research focused on computer-assisted detection and evaluation of breast cancer using digital pathology. He holds an MTech in Biomedical Engineering from IIT (BHU) Varanasi, where he received the Gold Medal, and a BTech in Biomedical Engineering from West Bengal University of Technology. During his doctoral training, he held the Innovation in Science Pursuit for Inspired Research (INSPIRE) Fellowship from the Department of Science and Technology (DST), Government of India; the Raman-Charpak Fellowship (IFCPAR/CEFIPRA); and the Newton-Bhabha PhD Placement Fellowship (British Council and DST), which opened the path to achieve international research training at Université Pierre et Marie Curie, France, and the University of Warwick, UK.
A central strand of Professor Saha’s research is cancer patho-epidemiology: understanding how information from routine pathology images, molecular data, and clinical records can illuminate cancer risk and tumour behaviour across populations. His work has demonstrated how deep learning applied to benign breast biopsy images can identify women at elevated risk of future invasive breast cancer, for which he received the DCEG Outstanding Paper Award for a publication in JNCI Cancer Spectrum. In parallel, he contributes to radiation epidemiology research, including the development of computational methods to estimate radiation doses to organs at risk during radiotherapy and the epidemiological study of long-term cancer outcomes in survivors treated with radiation. More broadly, his research spans lung cancer genomics, never-smoker lung cancer characterisation, and multimodal predictive modelling integrating imaging, genomic, and clinical data.
Professor Saha has received numerous recognitions, including the NCI Director’s Award, the DCEG Fellows Award for Research Excellence, multiple NIH Fellows Awards for Research Excellence (FARE), NIH Intramural Informatics Tool Challenge Awards, the NIH Summer Research Mentor Award, and the Outstanding Associate Editor Award from IEEE Transactions on Artificial Intelligence. He serves as Associate Editor for IEEE Transactions on Artificial Intelligence and Pattern Analysis and Applications, and as an Editorial Board Member of BMC Medical Informatics and Decision Making and BMC Artificial Intelligence.
At Ahmedabad University, Professor Saha aims to collaborate in building a research and teaching programme in public health data science and computational epidemiology. He is particularly interested in applying these approaches to disease challenges relevant to India and South Asia — spanning cancer, infectious diseases, and chronic conditions. He will also work in fostering interdisciplinary collaborations across the University’s schools of public health, engineering, life sciences, social sciences, and management.
Professor Saha’s research lies at the intersection of public health, epidemiology, biomedical informatics and data science. His work focuses on understanding the factors that influence disease risk, early detection, health outcomes and survivorship across populations. He is particularly interested in generating evidence that can support disease prevention, improve population health and inform public health policy and practice.
A major focus of his research is cancer and population concerning health challenges that adversely affect the life’s longevity. His work seeks to understand how diverse sources of health information, including clinical records, pathology and radiology data, genomic information and population-based datasets, can be used to better understand disease patterns, identify individuals at higher risk and support strategies for prevention and early detection. Through this research, he aims to contribute to more effective and equitable approaches to disease control and healthcare delivery.
Professor Saha also works on broader methodological and population health questions that extend beyond cancer and life expectancy condition. His previous research has included studies related to infectious diseases, critical care and clinical decision support. At Ahmedabad University, he aims to collaborate with researchers across public health, life sciences, engineering, data science, social sciences, management and clinical disciplines to address health challenges relevant to a new direction focusing the affected or, high/low risk population in India and South Asia.
A cross-cutting theme of his work is the responsible and reproducible use of health data for the public good. He is interested in developing analytical approaches and research tools that strengthen evidence generation, support transparent research practices and enable collaborative efforts to improve health outcomes at the population level.

Professor Saha teaches courses to undergraduate, postgraduate and doctoral students at Ahmedabad University. His teaching uses experiential learning, problem-based learning, interdisciplinary and multidisciplinary approaches, co-teaching and ENABLE pedagogies. He has designed curricula for several doctoral courses, with more in development. He is also building courses for the Master of Science in Health Data Science, which launches in July 2027. These cover core areas of the field, including artificial intelligence, machine learning, deep learning, computer vision, natural language processing and genomics. In the classroom, he puts humility first, which he believes makes for better learning.
Courses taught, currently taught, or approved for upcoming semesters:
Professor Saha has been invited each year since 2021 to teach graduate students at the Innovation Center for Biomedical Informatics, Georgetown University, Washington, DC. He designs and delivers lectures and hands-on laboratory sessions in biomedical image computing, imaging informatics and applied artificial intelligence. His teaching connects methods to real clinical and research data, using active learning and case-based problem solving.
Professor Saha serves on the editorial boards of leading journals in artificial intelligence and medical informatics, and he reviews manuscripts for journals in medical imaging, artificial intelligence, public health, epidemiology, cancer and biomedical engineering.
Professor Saha has served in leadership, program committee and organizing roles for international conferences, workshops and symposia.
