I completed both my BSc (Hons) Psychology degree and PhD (Cognitive Psychology) at the University of Leeds. My doctoral research investigated short-term auditory memory and forgetting, which I completed in 2011. I began working at the University of Wolverhampton in 2011 and am currently the Deputy Course Leader for our undergraduate psychology degrees and Senior Personal Tutor.
I teach widely on the psychology courses and lecture on various modules including Research Methods in Psychology: Basic, Cognitive Psychology and Cognition and Individual Differences.
I am a member of the Applied Cognition and Individual Differences research group and conduct experimental investigations into memory and forgetting. I am particularly interested in understanding how short-term representations are encoded, maintained and lost.

Current Research Projects
Retroactive interference in visual working memory. On-going research is exploring how different types of distraction affect visual working memory. There is particular emphasis on the similarity between the to-be-remembered object and the distracting event.
Specificity of proactive interference. Proactive interference occurs when old memories disrupt the ability to form new memories. Some research has highlighted a form of long-lasting proactive interference and a new project, supported by an Experimental Psychology Society grant, is exploring the nature of interfering events from the recent past.
