Understanding global health ethics requires insight into factors that influence inequalities in global health such as economic disparities, extreme poverty, limits on human rights, political oppression, and unequal distribution of research funding. I review some ethical issues related to global health, with a focus on global infectious disease research. Significant ethical concerns include inequities and disparities in national and institutional capacity to conduct global health research on infectious disease because these can influence the extent to which low resource countries benefit from the research. Research funding for global health or infectious disease often comes from the governments and institutions of developed countries and is allocated based on their institutional priorities, which may not align with those of the developing country. When they do align, developing countries may lack the necessary research, manufacturing, and logistical capacity to discover, produce, and distribute medicines and/or vaccines for infectious diseases within their countries. Research ethics guidelines evolve iteratively to help global health practitioners and researchers navigate concerns involving global health and infectious disease. There is an ongoing need for legal and regulatory frameworks, support for research capacity building – including ethics capacity, and systems to audit the impacts of capacity building programs. While partnerships are important to carrying out global health research, inequities between high and low resource countries drive ethical challenges in global health and infectious disease work. Recognizing and mitigating these inequities is a core challenge in global health research ethics supported by wider efforts toward decolonization.


Randall Waechter is Associate Professor in the School of Medicine (SOM), Assistant Dean in the School of Graduate Studies, and Associate Director of Research at St. George’s University (SGU) in Grenada, West Indies. He teaches research ethics, develops and oversees graduate degree programs, and oversees all research activities at the University. He is a Cognitive Neuroscientist by training, and has been conducting Global Health Research on infectious diseases and child neurodevelopment from within LMICs for more than 10 years. He also implements and examines the effectiveness of social-emotional interventions in early childhood on mental health across the lifespan.

Jerome T. Galea, PhD, MSW

Assistant Professor, School of Social Work

University of South Florida

The need for mental health services globally is unprecedented, especially in the context of the COVID-19 pandemic. Yet most people in both high and low-resource settings in need of mental health services go without, creating a mental health “service gap.” The field of Global Mental Health is dedicated to closing that gap. Today, Dr. Galea will speak about integrated HIV and mental health care in the context of increasing access to evidence-based mental health services for all.


Dr. Galea is an Assistant Professor of Social Work at the University of South Florida, Lecturer at Harvard Medical School, and a Global Mental Health implementation scientist. He has extensive experience in the implementation of low-intensity mental health interventions in Lima, Peru; Chiapas, Mexico; and Tampa, Florida.

Reflecting on years of partnership, Drs. Breanne Lott and Biniyam Tefera Deressa will share how they are collaboratively working to address one of the greatest global health challenges this century: cancer inequity. With complementary skillsets in public health and clinical care, they have teamed up to conduct research, improve cancer services and data collection systems, and design and implement new & innovative health interventions in Ethiopia since 2019. Foci of their projects span cervical, breast, esophageal, and other cancers, as well as broader issues and initiatives such as developing a cancer registry. This year, they were jointly awarded, together with Dr. Purnima Madhivanan, an American Association for Cancer Education grant for a breast cancer project that, to date, has trained more than 50 health professionals, launched a far-reaching mass media awareness campaign, screened more than 500 individuals for breast cancer, and elevated the voices of survivors for advocacy and engagement with local, regional, and national stakeholders and policymakers. Additionally, they are evaluating the impact of a first-of-its-kind psychosocial support group on the quality of life for breast cancer patients and survivors, for which Dr. Biniyam has been awarded a Global Health Equity Scholar Fellowship.

Drawing from these concrete examples, the pair will discuss practices they’ve fostered for a mutually beneficial global health relationship including their approach to peer mentorship, bidirectional learning, and capacity building. They will also share practical tips on how partners from high-income and low-income country contexts can leverage their strengths such as access to funding, patient populations, and diverse global networks.


Breanne Lott, Ph.D., M.P.H., is an Assistant Professor in the Department of Epidemiology & Population Health at Albert Einstein College of Medicine in the Bronx, New York. Prior to joining Einstein faculty, she was a Global Health Equity Scholar and Postdoctoral Research Associate at UA’s Mel & Enid Zuckerman College of Public Health. She is also a two-time MEZCOPH alumnus, studying Health Behavior Health Promotion (Ph.D., 2021) at the Tucson Campus and Public Health Practice (M.P.H., 2017) at the Phoenix Biomedical Campus. Dr. Lott’s experience in Ethiopia spans the past decade from her time as a Peace Corps Volunteer (2012-2014) to NIH-funded pre- and post-doctoral research and training fellowships as a Cancer Epidemiology Education in Special Populations Fellow (2019) and GHES (2021-2022). She enjoys using social behavioral research and implementation science lenses to ask scientific questions about how cancer is perceived cross-culturally, how cancer screening and prevention efforts are implemented, and how global public health practitioners can reduce cancer burden in underserved populations and under-resourced settings. Most recently, Dr. Lott and colleagues at the Montefiore Einstein Cancer Center have received American Cancer Society support for a cervical cancer screening initiative in the Bronx and she continues to expand her global health network, collaboratively developing projects to investigate HIV-associated malignancies in Rwanda and Cameroon.

Biniyam Tefera Deressa, M.D is an Assistant Professor of Clinical Oncology at Adama Hospital Medical College, in Ethiopia. Currently, he is a Global Health Equity Scholar (GHES) Fellow at Addis Ababa University and University of Arizona.

Accessing care for HIV and cervical cancer prevention are challenging enough on a normal day in north-central Nigeria. And that was before the COVID-19 and all of the challenges that the pandemic brought to healthcare settings and communities globally. This presentation explores some of the specific ways COVID-19 impacted routine care at the AIDS Prevention Initiative Nigeria (APIN) Clinic in Jos, Nigeria and discusses the potential long-term consequences of those impacts on HIV management and cervical cancer prevention in this setting.


Dr. Magdiel Habila is the Associate Director for Outcomes Research, Oncology in the Center for Observational and Real-World Evidence at Merck. Prior to the start of her career at Merck, Dr. Habila completed her Master of Public Health in Epidemiology (2019), MS in Health and Pharmaceutical Outcomes (2022), and PhD in Epidemiology (2022) at the University of Arizona. During her time as a doctoral candidate, Dr. Habila was an NIH-Fogarty Research Fellow with the Global Health Equity Scholars (GHES) program. She completed a mixed methods study examining barriers and facilitators to cervical cancer screening for women living with HIV in Jos, Nigeria under the mentorship of Professor Jonah Musa at Jos University Teaching Hospital and Dr. Madhivanan at the University of Arizona. Dr. Habila’s interests are in cancer epidemiology, specifically breast and cervical cancers in women of African decent and in the ways in which pharmacoeconomics can be applied to addressing cancer-related health disparities.
