I received the PhD degree in biomedical engineering (bioelectrics) from Science and Research Branch, Islamic Azad University, Tehran, Iran in 2014. In Sep 2014 I awarded the facility to work with Iran?s National Elite Foundation on design of an EEG-based emotion recognition system. I am now a postdoctoral scholar with mentorship of Drs. Mednick and Bazhenov at the University of California, Riverside. I am also a faculty member in the Department of Biomedical Engineering, Dezful Azad University, Iran. My research and teaching interests include theory and application of biomedical signal processing and pattern analysis in neuroscience, affective computing, and medical diagnostic.

The research I have performed during my PhD was on recognition of music-induced emotions by information fusion of forehead biosignals (acquired from Frontalis as well as left and right Temporalis muscles) and electrocardiogram. My work has suggested that appropriate fusion of these biosignals increased classification accuracy. In addition, by applying a novel feature which is extracted from the correlation of heart rate variability and forehead biosignal features, we could reveal the difference between perceived and felt emotions.

My work currently focuses on understanding mechanisms of memory consolidation using both experimental work in humans and computational models. A growing body of research shows that sleep facilitates the consolidation of memories. The central aim of the project that I will be involved with is to utilize different interventions to investigate the specificity of sleep-dependent memory by 1) sleep feature 2) memory, and 3) the applied agent (e.g., pharmacological agents).
