Research interests include:

• Sleep deprivation effects on emotional processing
• Age-related cognitive resilience
• Interaction between affective bias and memory integration
• Neurophysiological responses to stress
• Positivity effect in aging populations

His publications since 2015 include experimental studies on:

• Emotional working memory load
• Age-dependent stress responses
• Reinforcement learning under sleep restriction
• Perceptual constancy of facial expressions
• Task-unrelated thought mechanisms

Since 2017, he has lectured on statistics and sleep-related topics while supervising cognition laboratory sessions. His methodological approach combines computational modeling with neuroimaging techniques like MEG to explore sleep-stress-recovery relationships.
