These papers have appeared in journals of international and national repute, such as the Journal of Business Research, the European Journal of Marketing, Business Strategy and the Environment, Studies in Higher Education,  the Journal of Marketing Management, and the Journal of Services Marketing, as well as conferences.

Harjit’s research with impact is very much about completing projects that make a difference to the business or the individual. Depending on the project’s remit, over the years, Harjit has used both quantitative and qualitative methods to undertake research for different types of businesses. This has ranged from setting up customer satisfaction-type projects to projects looking at purchase decision-making behaviours. Being in a position to draw on this reservoir of expertise means that Harjit can support businesses in fully understanding the needs of their customers and markets.  

Harjit is running a project that deals with how people make decisions related to their late-life financial needs so that it will be possible to prevent certain cohorts from facing financial difficulties during their later years. Although much econometric data is available about how much people save, it is important to gain more insight into the behavioural reasons that shape their decisions.

More recently, Harjit has set up a project with a colleague that examines sports officials' challenges on the field of play when officiating. The project aims to find ways to reduce the demands placed on officials and make their jobs easier.

Harjit and Dr Lindsey Appleyard were the founding co-director of Credit U, a platform designed to help those facing the most significant risk of being excluded from mainstream financial products have access to community-based regulated financial services to support their specific needs.  

Harjit collaborated with colleagues from another university to establish the UK’s first financial services trust index. This index gauged trust levels across various financial services. Unlike binary questions, the trust index considered the factors that contributed to building trust between financial services companies and their customers. 

Before joining CBiS, Harjit held various university leadership positions.
