Dr. Emmanuel N. A. Tetteh’s formal training is in the pragmatism of constructive action research methods, paradigms and modalities of action learning inquiries, experiential research methodologies, community services, human services administration, public administration, and public policy analysis, where he has served in various faculty, voluntary, and professional role of services. As a result, he has a vast range of professional experience, ranging from over 32 years of Christian foreign missions and ministerial projects, faith-based initiatives, pastoral psychotherapy for self-improvement counseling services, community-based service, nonprofit management, security management, higher education administrative services, curriculum development and assessment, and teaching/learning facilitation for adult learners from diverse backgrounds.

In 1998, Dr. Tetteh moved on to higher education administrative support positions in students’ advisements, academic support services, student financial services, attendance data analytic management, coordination of recruitment initiatives, and enrollment and retention management. He then transitioned as of 2001 to higher education teaching positions at both online and brick-and-mortar schools, teaching undergraduate/graduate courses across multidisciplinary curricula such as research methods, human services, business administration, management sciences, human resources management, nonprofit management, philosophy, ethics, public policy, and administration, etc.

Thus, Dr. Tetteh has enormous experience as an expert or purview in action research/participatory action research paradigms, needs-assessment studies, social science research, program evaluation, qualitative research paradigms, mixed methods research, and curriculum development. In addition, he served as dissertation chair and mentor, subject matter expert, and research methodologist on several Ph.D. and DPA doctoral student dissertation committees at higher education institutions.

At Walden University, Dr. Tetteh serves as Contributing faculty in the School of Public Policy & Administration. Dr. Tetteh’s current research interests focus primarily on teaching research methods, action research/participatory action research paradigms, dissertation coaching and mentoring, and public policy and administration. Through action learning/action research and program evaluation projects in his master’s degree program that led to a grounded theory, Dr. Tetteh developed and coined the metaphor of the “Communal Photosynthesis” phenomenon in 2001.

Building upon his master’s thesis action research/program evaluation project, he applied the qualitative heuristic method of inquiry in triangulation with a symbolic interactionism approach to explore further ways by which this Communal Photosynthesis metaphor can provide a theoretical and pragmatic model for homeland security management in the field of service-learning.

In 2015, Dr. Tetteh developed an intriguing action research model grounded in the systemic thinking of his Communal Photosynthesis metaphor. Dr. Tetteh offered a personal reflection on the meaning of action learning/action research and introduced the “creative-reflective methodology,” unraveling the Identify, Act, Reflect, Evaluate, and Produce (IAREP) model for participatory action research. In 2019/2023, he also developed an Internet of Things (IoT) action-learning solution model of big data policy-analytic epistemology published in the Handbook of Research on Big Data and the IoT and Research Anthology on Big Data Analytics, Architectures, and Applications, respectively.

He has presented at numerous Scholarly research conferences, including the Action Learning, Action Research Association, American Society for Public Administration, Collaborative Action Research Network, and Religious Associations. Dr. Tetteh has published peer-reviewed articles, books, and chapters in Research Handbook on data analytics, public policy, and democratic governance in higher education administration. In 2005–2013, he was recognized by the Who’s Who in America for his scholarly contributions to the research discovery field.

Finally, as of 2013, he serves on the Executive Board of Directors for Action Learning, Action Research Association, as its International Vice President and serves as a Designated Official Representative to the United Nations (UN), for which ALARA is granted a Special Consultative Status to engage in several ways with the Economic and Social Council (ECOSOC) and UN subsidiary bodies, the Human Rights Council and, under specific conditions.
