Ramanujam addresses pressing challenges in women’s cancers, specifically, cervical and breast cancer. Ramanujam creates technologies that transform complex diagnostic instruments and therapies into accessible, affordable, and appropriate solutions. Several of these products are now being used in several countries in the U.S., Latin America, and Africa. She has developed a network of partners including academic institutions and hospitals, non-governmental organizations, ministries of health, and commercial partners to implement these technologies in diverse healthcare settings globally.

She has used her expertise in imaging and human-centered design to develop the Pocket colposcope which is on the WHO list of devices for cervical cancer imaging. A sister device, the Callascope is a self-use speculum-free imaging device, which allows women to screen themselves privately without the need for an intrusive pelvic exam. She has developed a translational microscope called the CapCell Scope to identify biomarkers of metabolism that reflect tumor behavior, including growth, proliferation, and treatment resistance, aimed at informing drug selection for breast cancer treatment. She has developed an ultra-low-cost injectable liquid ablation therapy that disrupts tumors locally as well as elicits an anti-tumor immune response to address an important gap – the lack of access to surgery to the world’s most vulnerable populations.
