  • Faith

    Industrial Liaison Officer

Faith has a broad background in psychology, maternal and child health with specific training and expertise in phenomenology and survey research designs and thematic data analysis in qualitative studies. I have a vast amount of nursing and midwifery clinical/teaching experiences. My wide remit of interests led me to undertake a second masters and PhD degrees in midwifery in the United Kingdom. My important work is in the area of evidence-based practice in childbirth in Nigeria and Africa as vital in the promotion of women’s autonomy and well-being during the birthing process. My Ph.D study titled “Perceptions and experiences of mothers, midwives, and obstetricians concerning birthing position and perineal trauma: A mixed methods study based in Nigeria”, has led to excellent collaborative work undertaken in Port Harcourt, Nigeria. This collaborative work led to an on-going project “The making Normal Birth a Reality in Port Harcourt, Nigeria”, which involves educating and training mothers, midwives, obstetricians and the community at large to implement evidence based normal birth practices which will enable women to birth in upright position to promote better health outcomes and reduce rates of perineal injuries. This is the factor that led to my invention of a birthing chair to support women birth in various upright positions. I am also engaged in other collaborative studies with international counterparts as PI or co-investigator in Canada, UK, and Australia. Based on these previous experiences, I understand the importance of team work among project members and of building a realistic research plan, timeline, and budget to meet the target. Faith is Nigeria's first doctorate in midwifery awarded by University of Chester UK and was award the Alumni Laureate award of the University of Nottingham, UK in 2018
