Working Paper 1 : Sustainability Accounting Literature: A Review of the Concept and Definitions of Sustainability Accounting  

Obasanjo David Okekunle, Neeta Shah and Charles Agyeman

This is a chapter in my PhD thesis that I am currently working on for publication. This paper employs a systematic literature review, following Mathews' (1997) methodology, to examine the development of sustainability accounting over 53 years, from 1971 to 2023.  

Working Paper 2: ESG disclosure Quality and Performance - Does Crisis Time Differ? Evidence from Africa and the UK

Obasanjo David Okekunle, Akindapo Abass Alimi and Saheed A. Shittu

This study examines how the quality of ESG disclosure, evaluated by the Bloomberg ESG Disclosure Score, affects the financial performance of Africa’s top 250 listed companies. It also explores how governance quality moderates this relationship before and after the COVID-19 pandemic, especially in comparison to the economy most affected by the pandemic.

Students as Researchers Project Strand 2: The Impact of Authentic Assessments on Student Outcomes in Accounting and Finance 

£15,000 project funded by Quintin Hogg Trust Fund, University of Westminster.

This study investigates how authentic assessments influence student outcomes in Accounting and Finance.

Students as Researchers Project Strand 1: Sustainable Development Goals (SDGs) Prioritisation and Disclosures by UK Universities

£5,000 project funded by Quintin Hogg Trust Fund, University of Westminster.

The project used content analysis to examine how UK universities disclose their sustainable development practices. The top 30 UK universities, ranked by the Times Higher Education (THE) World University Rankings in 2025, were selected through purposive sampling. Analysis of SDGs reports was conducted using Python scripts and manual methods, with results presented through descriptive statistics and visualisations. I developed the Python scripts and research methodology used in this project.

STEP-UP Project : Digital Research Technical Champion Scheme

The STEP-UP scheme is a project in collaboration with four partner universities, Imperial, UCL, King’s College London, and the University of Westminster, to promote best practices in digital research. Read more about the STEP-UP project here.

As the digital research technical champion for the STEP-UP scheme, I engaged researchers at my school with related digital research tools and ideas. In collaboration with the champions at my university, we have conducted a survey to understand the challenges researchers across the University of Westminster face regarding digital research tools. I have also undertaken one-to-one sessions with researchers to understand their challenges and referred them to appropriate resources.
