Personal History:

Dr. Adebamowo’s education includes training in medicine, surgery, oncology and epidemiology. In 1984 he received his MB ChB Hons from the University of Jos in Nigeria, after which he completed post-graduate training in surgery at the University College Hospital in Ibadan, Nigeria. In 2004 he earned a doctorate in Nutrition Epidemiology with a minor in Biostatistics from Harvard School of Public Health, Boston.

Before coming to the University of Maryland, Dr. Adebamowo worked as a professor of surgery, lecturer in nutrition epidemiology and bioethics, and Director of the Institute for Advanced Medical Research and Training at the University of Ibadan in Nigeria, and as the Director of the West African Bioethics Training Program, also in Ibadan, Nigeria.

Dr. Adebamowo currently is a Professor in the Division of Cancer Epidemiology, Department of Epidemiology and Public Health and a member of the Greenebaum Cancer Center and the Institute of Human Virology at the University of Maryland, Baltimore School of Medicine. He also serves as Director of the Center for Bioethics in Ibadan, Nigeria; Director of the West African Framework Program for Global Health; Director of the Nigerian National System of Cancer Registries and Chairman of the National Health Research Ethics Committee of Nigeria.

Dr. Adebamowo is a member of the Population Science Program within the University of Maryland Marlene and Stewart Greenebaum Cancer Center Program in Oncology. Population Science researchers collaborate with investigators throughout the University of Maryland System to identify determinants of cancer etiology and survivorship, characterize cancer-related health behaviors, and translate basic discoveries into behavioral cancer prevention and control interventions. Dr. Adebamowo’s research centers on improving knowledge of the molecular biology of HPV associated cancer (cervical and head and neck cancer) and breast cancer. His research also includes identification of new genomics and epigenomics biomarkers of cervical cancer.

Dr. Adebamowo is presently the principal investigator on several training grants from the National Institutes of Health and the Centers for Disease Control and Prevention. His research is funded by the National Institutes of Health and the Wellcome Trust in the United Kingdom.

Research Interests:

Host germline, somatic, and HPV genomics and Cervical cancer risk in African women

Dr. Adebamowo works with partner institutions in Nigeria and Zambia to implement research studies in viral oncology that are exploring the role of Human Papilloma Virus in cervical, and head and neck cancers. In Nigeria, he has:

  • Established a systematic cervical cancer screening program in Nigeria and is collaborating with others in an effort to cover 70% of Nigeria’s 80 million women with at least once in a lifetime cervical cancer screening program;
  • Built an HPV, vaginal microenvironment and cervical cancer risk research program that has already contributed to the identification of an association between Lactobacillus iners rich vaginal microbiota, specific human genetic variations, and prevalent high risk cervical HPV infection. This has implications for improved understanding of the host and vaginal microenvironment’s role in cervical carcinogenesis as well as for risk stratification in cervical cancer and understanding of disparities in HPV infection and cervical cancer in the United States;
  • Continued to characterize the pattern of persistent high risk HPV infection which supports studies of the epidemiology and secular trend in high risk HPV infection. This is linked to a nation-wide cancer registration system that tracks incidence of cancers including those associated with HPV infection – Head and Neck, Anal and Cervical cancers. So far these studies have demonstrated that the pattern of prevalent high risk HPV infection in Africa may be different from other parts of the world, which may affect efficacy of currently available HPV vaccines.

These research formed the foundation projects for the African Collaborative Center for Microbiome and Genomics Research – an H3Africa funded collaborative center at the Institute of Human Virology, Nigeria.

Obesity, Nutrition and Physical Activity

In recognition of the role of obesity as the major predictor of mortality and morbidity in the world today and the second most important risk factor for cancer in Sub-Saharan Africa, Dr. Adebamowo’s group is studying nutrition, obesity and physical activity epidemiology in Nigeria, including the development and validation of the Nigerian Food Frequency Questionnaire and Food Composition Database.

In collaboration with colleagues at the Harvard School of Public Health (HSPH), Dr. Adebamowo’s group is working on dietary substitution to reduce intake of energy dense, low fiber foods in Nigeria as part of the GNET initiative.

A second collaboration with HSPH is focused on developing a large prospective cohort of 500,000 Africans for non-communicable diseases (NCD) research and training in Africa called PaCT. The objective of this program is to identify risk factors for the emerging epidemic of NCD in Africa, conduct multi-country comparison studies and train a generation of African researchers/scientists.

Dr. Adebamowo is co-PI of a Wellcome Trust funded H3Africa Collaborative research project spanning 12 African countries and focused on the environmental and genetic risk of Diabetes Mellitus in Sub-Saharan Africa.

Nigerian National System of Cancer Registration

Clement has also worked with the Nigerian government to resuscitate the Nigerian National System of Cancer Registration which has successfully returned Nigerian data to the magisterial Cancer in Five Continents publication of the World Health Organization and International Agency for Research against Cancer after more than 30 years of absence. Given that Nigeria constitutes ~20% of Africa’s population, this significantly changes the proportion of Africans who are covered by a population based cancer registration system.

In addition to the generation of incidence data on cancer in Nigeria, the NSCR has become a regional hub for training and capacity development for cancer registries in West Africa and is a member of the African Network of Cancer Registries.

The cancer registration project is also collaborating in using Geospatial mapping to study cancer incidence in Nigeria and linkage research of HIV and Cancer registries databases to improve the epidemiology of AIDS Associated Cancers in Africa.

Nigerian National Health Research Ethics Committee

Since 2005, Dr. Adebamowo has led the West African Bioethics Training program to work in partnership with regional bioethicists, research institutions, teaching hospitals, universities, international NGOs and governments to develop the Nigerian National Health Research Ethics Committee and several institutional research ethics committees. He also led the effort to create a National Health Research Ethics Code for Nigeria and is currently developing additional infrastructure to strengthen health research ethics review in the country through mentoring, training and development of additional guidelines for vulnerable populations, a system of confidential certification and electronic ethics review system. The overall goal is to promote the highest ethical and scientific standard in research and enable international collaborative research.

Training Interests:

Dr. Adebamowo has a deep and abiding interest in training and capacity development, especially of young scientists in Africa. He is a leader in use of video conferencing facilities at IHVN, Abuja Nigeria and the NIH/FIC supported Elluminate web conferencing facilities to teach a wide range of topics to students throughout Nigeria. As PI of 3 NIH training grants, Dr. Adebamowo has supported the training of faculty, scientists and physicians from several institutions in Nigeria in cancer registration, cancer epidemiology, life-course epidemiology, quantitative and qualitative research methods, use of the case-method to teach NCD epidemiology, genetics and epigenetics. This teaching portfolio continues to increase as demands arise for knowledge and new capacity from collaborating institutions.
