Nimmi Ramanujam

Ramanujam's research on women's cancers has centered on translational and laboratory research of relevance to breast and cervical cancer.[13][14] While her guiding principles are similar across breast and cervical cancer, the technical challenges needed to tackle these cancers are inherently different. In the case of cervical cancer prevention, her focus is to develop strategies that reduce attrition to treatment including early screening and diagnostics.[15] In the breast cancer care cascade, clinical care has principally pivoted towards a focus on how to inform the effectiveness of cancer therapy whether it is surgery or systemic therapy, and that is where she has focused her efforts via molecular and metabolic imaging.[16] A third area in her research program focuses on low cost ablative strategies for local control of cancer in resource limited settings.[17] She has also created two companies, Zenalux[18] and Calla Health,[19] to commercialize her breast and cervical imaging products, respectively. Additionally, she has created three social innovations programs, WISH to impact cervical cancer prevention in low resource settings, IGNITE to scale social innovation education to students globally and the Calla Campaign to bridge inequities in sexual and reproductive health inequities through story-telling and art.[20]

She has received recognition for her work through the TR100 Young Innovator Award from MIT, the Global Indus Technovator award from MIT, Era of Hope Scholar awards from the DOD, the Stasnell Family award from the Pratt School of Engineering at Duke, the Emerging Leader in Global Health Award from the Consortium of Universities in Global Health, the Social Impact Abie Award from AnitaB.org, the Biophotonics Technology Innovator Award from the International Society for Optics and Photonics, and the Women in Molecular Imaging Leadership Award (WIMIN) from the World Molecular Imaging Congress (WMIC).[21] She is a fellow of several optical and biomedical engineering societies including OSA, SPIE and AIMBE. She has also been elected to the National Academy of Inventors and is a Fulbright fellow.[22] She is co-editor of the Handbook of Biomedical Optics.[23] She has presented the global impact of her work at the United Nations. She has been a TedX speaker.[24]
