Atrina is a Fellow in Psychological and Behavioural Science at LSE, where she completed her PhD and MSc with Distinction and was awarded the Rob Farr Award for Best Dissertation. Her research examines how people make decisions in their everyday lives, with a particular focus on maintaining ecological validity through naturalistic observation and innovative methodologies.

Using Subjective Evidence-Based Ethnography and other multimedia and novel approaches, Atrina's work captures the complexity of human decision-making as it unfolds in real-world settings. This methodological approach allows for a deeper understanding of how people navigate choices in their daily lives, from consumer decisions to sustainable behaviours, while maintaining the rich context in which these decisions occur.

Through her emphasis on naturalistic observation and real-world applicability, Atrina's research aims to bridge the gap between laboratory findings and the complex realities of human behaviour in modern societies. This approach helps ensure that research findings remain relevant and applicable to the actual challenges people face in their daily lives.​​​​​​​​​​​​​​​​

At LSE, Atrina has taught courses in consumer psychology, social and organisational decision-making, and international human resource management. Her commitment to higher education is recognised through her Fellowship of the Higher Education Academy (FHEA) and her Class Teacher Awards.
