Dr Hakim Mezali

Senior Lecturer in Business Analytics and Quantitative Methods

Professional Biography

Hakim is a Senior Lecturer at Regent's, where he leads modules on Business Analytics and Quantitative Methods. He was previously a lecturer at the University of Hertfordshire and also worked at Brunel University London.

In addition to these roles, has worked for two pharmaceutical companies, where he was involved in clinical trials for their respective modelling programming and statistical departments.

Hakim also holds a PhD from Brunel University London in Mathematical Statistics, PGCert in Education and a BSc Hon in Mathematics.


  • PhD in Mathematical Statistics PGCert in the Higher Education
  • BSc Hon in Mathematics Fellow of the Higher Education Academy, and currently working for the Senior Fellowship.

Relevant Past Employment

  • 2014–2018: Lecture, Business School, University of Hertfordshire, UK
  • 2013–2014: Teaching Fellow, Department of Mathematics, Brunel University, London 
  • 2008–2009: Data Analyst, Banking Sector - Royal Bank of Scotland, UK
  • 2006–2008: Statistical Programmer - Pharmaceutical Sector, Cmed Research Limited UK
  • 2005–2006: Statistical Programmer - Pharmaceutical Sector, GlaxoSmithKline PLC UK


Hakim is presently contributing to Regent's research profile through various research publications. He has also published two journals in the Journal of Operational Research Society (JORS), where the overall quality of submissions was judged on average to be internationally excellent.

He has also published a research conference paper on research informed teaching in statistics, and submitted another paper that is currently under review.

Additionally, Hakim is currently working in collaboration with an external member of staff on the fifth paper. Although he considers himself an early career researcher, he anticipates entering the Research Excellence Framework 2020, by collaborating with other members of staff at Regent's. Hakim's aim is to produce a quality publication, which he hopes will have an impact on society.

Research Interests

Hakim's research interests fall under two categories:

  • Construction of data-driven models to reproduce and explain the impact of complex behaviours on health outcomes and financial modelling of risk and portfolio indexation/enhanced indexation
  • Applied statistics, with particular emphasis on quantile regression methods 

For the modelling of complex behaviours, Hakim is interested in how the course of events over an individual's lifetime can contribute towards an adverse health outcome. He focuses on the problem using an agent-based perspective, whereby interactions in behaviours of interests are modelled at micro levels, which are then aggregated to explain the impact/burden of a particular outcome (e.g. mortality) on the general population.

Furthermore, portfolio-enhanced indexation focuses on selecting a sub-section of stocks from the universe of stocks trading in a particular market, such as FTSE 100, that will outperform the index, which is by default a benchmark on the performance of all stocks making up the index.The decision faced by investors is then to select the "right" stocks and invest an appropriate proportion of their wealth in order to ensure the performance of their portfolio will be better than that of the index.

By utilising the history of returns for each stock within an index, the decision on which stocks to invest in and what quantity can be constructed as a mixed integer optimisation problem. However, most of the approaches to date do not account for uncertainties associated with holding the same stocks for a given period, say three months, into the future from the selection date.

Hakim's overarching goal is to embark on projects that attempt to quantify the uncertainty of selected portfolios by using probabilistic techniques using latent clustering methodologies. He has developed a strong interest and ability to work and collaborate in multidisciplinary research projects.

His research work has been a combination of independent research and fruitful national and international collaborations with colleagues with mutual interests and a complementary background/experiences.

Hakim's plans to secure funding are focused on the following areas of research: developing modelling, optimisation and control strategies, and understanding the current issues facing the NHS, such as investigating its "heavy" users, and using analytical tools and techniques – including database programming and data mining – to help the NHS improve its current patient services.

Another area for which Hakim hopes to secure funding is the development a risk prediction model to predict the probability of a patient being discharged by death, particularly for Chronic Obstructive Pulmonary Disease (COPD). The aim of this project is to develop a prediction model that the Care Quality Commission (CQC) in England would use to calculate the Hospital Standardised Mortality Ratio (HSMR).

Research Supervision

Hakim acts as master-level dissertation supervisor, through which he guides and supports students throughout the development of their dissertation and report.

In addition, will be attending the PhD supervision training at the University of Northampton in mid-September 2019. Alongside attending and completing PhD supervision training, he anticipates having the opportunity to act as a PhD supervisor.


In 2019, Hakim was awarded a Fellowship from the Higher Education Academy (FHEA).

Grants Awarded

In early 2019, Hakim submitted a project proposal on behalf of Regent's to the European Commission titled 'Im-NOVATE'; an innovation for inclusive migrant integration/adaptive public service support platform to the European Commission. This is a multi-million collaborative working project.

Professional Affiliation(s)/Accreditation

Fellow member of the London Mathematical Society and a fellow of the Royal Statistical Society.

External Examining

Hakim previously acted as an external moderator for the INTI International University & Colleges in Malaysia, between 2014-2018. He has also delivered a number of courses at the Hunan International Economics University in Changsha, China.

Conference Papers Given

Hakim has attended a variety of external courses and delivered numerous presentations at national and international conferences.

Other Outputs

Hakim is currently a statistical consultant for the Statistical Services and Consultancy Unit at the University of |Hertfordshire. He has also have delivered short courses in statistics at all levels for the same Consultancy Unit.

Teaching & Course Development

Hakim has contributed to the development and improvement of several courses in the Business Analysis Statistical Group curricula at the University of Hertfordshire Business School. At Regent's, he has helped with the preparation and development of new courses in multidisciplinary areas, in tune with market demand, and taken responsibility to deliver them efficiently.
