Evidence synthesis and meta-analysis
I am conducting a systematic review and meta-analysis of predictors of adolescent additional-language learning, bringing together evidence from psychology, education, linguistics, and cognitive neuroscience.
Lois Ann Parri
PhD Researcher
Department of Psychology
University of Cambridge
I’m a person-centred psychology researcher interested in how people experience and engage with digital tools and interventions. My PhD applies this to developing an individualised adaptive language-learning tool, with a focus on accessibility, and real-world usefulness.
About
Generalist researcher by experience.
I enjoy work that lets me tackle a variety of ideas, people, methods, and practical delivery. I’m happiest on projects where I can coordinate moving parts, engage with different groups, analyse complex information, and help turn research into something that's genuinely useful beyond academia.
Current work
What I’m working on now
My PhD uses adolescent additional-language learning as a context for a broader question: how can psychological evidence, lived experience, and PPIE inform digital tools that are usable, engaging, and genuinely accessible?
Adolescent Advisory Group
To ensure my research is informed by and relevant to the people it aims to understand and support, I have established an advisory group of adolescents. The group is active, and find more information here.
Psychology-led adaptive learning tool
I am supporting the development of a pilot adaptive language-learning tool, focusing on how research evidence can inform digital learning experiences that are practical, engaging, personalised, and accessible.
Research interests
Rather than one topic, I work across a few connected themes.
My work clusters around how people experience, engage with, and benefit from psychological research and digital tools, particularly in learning and mental health contexts, and how research can be made more person-centred, transparent, and useful in practice.
Digital tools and interventions
Digital tools for learning and mental health, digital working alliance, and how psychological evidence can inform tools that are practical, engaging, and useful.
Experiences, attitudes, and engagement
How people experience and make sense of digital interventions and tools, including acceptability, engagement, usability, trust, and perceived value.
Mental health and person-centred research
Psychosis research, cognitive remediation, digital mental health, participant-centred study design, and research that values people’s lived experiences.
Methods, synthesis, and open research
Systematic reviews, meta-analysis, qualitative and mixed methods, transparent workflows, accessible outputs, and making open science usable beyond specialist audiences.
Skills
What I bring to projects
I bring a mix of research delivery, participant-facing work, analysis, writing, synthesis, and coordination.
Research coordination
Recruitment, scheduling, participant engagement, research administration, documentation, and multi-stakeholder communication.
Mixed methods
Qualitative interviewing, thematic analysis, quantitative statistical analysis, systematic review, meta-analysis, and data preparation.
PPIE and facilitation
Public and patient involvement and engagement, advisory groups, accessible materials, and research shaped with people and communities.
Dissemination
Academic writing, public-facing communication, bilingual communication, and creative approaches to making research more accessible.
