Center Director

Dr. Ramanujam is an innovator, educator and entrepreneur. Her mission is to develop technology that will have wide reaching impact in women’s health. She directs the center for Global Women’s Health Technologies at Duke University where she empowers trainees at Duke and beyond to create impactful solutions to improve the lives of women and girls globally. 

Dr. Ramanujam has spent the last two decades developing precision diagnostics and most recently precision therapeutics for breast and cervical cancer, with a focus on addressing health disparities. She has more than 20 patents to-date and over 150 publications for screening, diagnostic, and surgical applications. She has raised over $30M of funding to pursue these innovations through a variety of 

funding mechanisms including NIH R01s and R21s, NIH Bioengineering Partnerships, NCI Academic Industry Partnerships, NIH Small Business grants and USAID funding. As the founding director of the Center for Global Women’s Health Technologies at Duke, she has developed a consortium of over 50+ partners including international academic institutions and hospitals, non-governmental organizations, ministries of health, and commercial partners; this consortium is working to ensure that the technologies developed at the center are adopted by cancer control programs in geographically and economically diverse healthcare settings.


Dr. Ramanujam’s research on women’s cancers has centered on translational and laboratory research of relevance to breast and cervical cancer. 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. 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.  A third area in her research program focuses on low cost ablative strategies for local control of cancer in resource limited settings. She has also created two companies Zenalux and Calla Health 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.

Dr. Ramanujam has received institutional awards for her work including the Global Indus Technovator and TR100 Young Innovator awards (MIT) and the Stansell Family award (Pratt School of Engineering, Duke). Additionally, she has been recognized by both private and government organizations including multiple Era of Hope Scholar awards (DOD), the Emerging Leader in Global Health Award (CUGH), the Social Impact Abie Award (, the Biophotonics Technology Innovator Award (SPIE), the Women in Molecular Imaging Leadership Award (WMIC),  and a Fulbright Global Scholar Award. Dr. Ramanujam is a fellow of several optical and biomedical engineering societies including OSA, SPIE and AIMBE. Most recently, she was awarded the Michael S. Feld Biophotonics Award and was appointed as the IEEE Distinguished Lecturer. She has presented the global impact of her work through presentations at the United Nations and TEDx events.

Executive Director

Marlee holds a B.S in Biology and M.S in Molecular and Cellular Biology from the University of Massachusetts. There she developed fluorescence reporter systems to monitor DNA damage in Escherichia coli. She is currently the Executive Director at the Center for Global Women's Health Technologies within the Biomedical Engineering Department at Duke. She is also a member of the Center for Global Women’s Health Technologies where her research focuses on the development of the Pocket Colposcope for cervical cancer screening in resource poor settings. She also directs DukeEngage Orange County, an immersion program that aims to empower young girls by giving them tools to help navigate social, economic and gender barriers. In 2016, she became a team leader for Bass Connections Peru. In this project, a diverse team of faculty, staff and student map the various stakeholders involved with the implementation of the Pocket Colposcope in Peru. 

Marlee Krieger began her appointment as the Executive Director of the Center for Global Women’s Health Technologies in October, 2018. Since being named Executive Director, Marlee has built and leads a diverse set of multidisciplinary educational programs, spearheads the Center’s international collaborations which focus on the clinical implementation of technologies developed at Duke, and has become widely successful in securing financial support for Center related research and education. Her research efforts focus on generating a deeper understanding of the scaling and adoption of novel healthcare innovations as well as the potential barriers to ultimate market acceptance.

Marlee directs the Calla Fellows Program, a 12-month rigorous internship for exceptional post-baccalaureates interested in women’s health and transformative technologies. 2019 marks the fourth year of this highly successful and competitive program. She also directs DukeEngage Orange County, an learning-based immersion program that aims to empower young girls by giving them tools to help navigate social, economic and gender barriers. In 2016, she began a Bass Connections program in Lima, Peru. In this project, a diverse team of faculty, staff and student map the various stakeholders involved with the implementation of the Pocket Colposcope in Lima. Marlee also serves as the Director of DukeEngage Orange County, which reflects the partnership with two non-profit organizations, Girls Inc. and Global Girls Glow. Each year, Marlee leads a team of eight Duke students to southern California to work with these community partners on empowering middle- and high-school aged girls through STEM education and artistic expression. Additionally, for the last four years, she has directed a Bass Connections program called, “Analysis of Bringing Elements of Referral Services to Community Care.” The goal of the program is to work with a team of healthcare providers, policy makers, lawyers and most importantly, students, to demonstrate that novel technologies developed at Duke using a process called human centered design can be economically viable in the community health setting. Like her involvement with DukeEngage and Bass Connections, many of the Center’s clinical, educational, and community outreach initiatives can be directly attributed to the leadership and organization that she has brought to the center.


Marlee is a founding member of the Center for Global Women’s Health Technologies, where she has served since 2007. She works closely with all members of the GWHT lab, including administrators, post-doctoral researchers, graduate and undergraduate students, and post-baccalaureate fellows to foster their professional development in conjunction with the continued growth of the Center. Additionally, she works with many members of the Pratt community as well as faculty, staff and students in numerous other departments across campus including, DGHI, Surgery, Ob/Gyn, Pathology and FUQUA and the Margolis Center for Health Policy. She obtained her undergraduate degree in Biology at the University of Massachusetts, where she also received a M.S. in Molecular and Cellular Biology.
