NCI Global Health Equity Panel

“It is in your hands to create a better world for all who live in it.” -Nelson Mandela

Our panelists, Dr. Arachu Castro, Dr. Evelyn Gitau, Dr. Ravi Kannan and Dr. Laetitia Rispel and GHIG fellow moderators, will facilitate a discussion on actions that the broader public health community can take to enhance equity and justice in global health research and practice. Attendees will learn about the panelists’ career trajectories in global health, the role of early career scientists in advancing global health equity and the panelists’ perspectives on ways that NIH can continue its commitment to reducing inequities in collaboration with partners locally and globally. Through deep discussion, attendees will gain an understanding of the challenges scientists face when implementing global health equity initiatives.


The NCI Global Health Interest Group (GHIG), established in October 2021, is a fellow-led NCI interest group aimed at facilitating learning and networking among fellows interested in global cancer research and control with a particular emphasis on work in low- and middle-income countries (LMICs). The group is open to all fellows (postbaccalaureate, predoctoral, postdoctoral, and clinical), across NCI, with interests in global cancer research and control with an emphasis on work in LMICs.

GHIG was founded by CPFP fellows Drs. Waruiru Mburu and Margarita Correa-Mendez with the vision to promote collaboration and knowledge-sharing between fellows, across NCI divisions, engaged or interested in issues of global cancer research and control. Current group leadership includes CPFP fellow Dr. Percy Guzman. With the guidance of GHIG Advisors, Mishka Kohli Cira, M.P.H.; Sudha Sivaram, Dr.PH., M.P.H.: and Lymarie Maldonado-Báez, Ph.D., M.S.; the NCI GHIG supports its members’ professional development in topics such as scientific communication, leadership, and career planning. As well as collaborate with NCI-CGH to provide guidance and input on CGH-led research, trainings, and partnership activities for fellows. The GHIG organizes and facilitates trans-disciplinary global oncology seminars, trainings, and networking opportunities with experts in the field. The first global health equity virtual panel titled, Diversity, Equity, and Inclusion in Global Health, will be held on July 19, 2022, and is open to the NIH-wide community.
