I joined the lab in January 2024 as a postdoctoral researcher. Prior to this, I obtained a B.Sc. in electrical engineering at the University of Tehran and an M.Sc. in electronics at Tarbiat Modarres University, Tehran, Iran. I did my Ph.D. in cognitive neuroscience at the Institute for Research in Fundamental Sciences (IPM) in Tehran, during which I worked with Dr. Maryam Vaziri-Pashkam and Prof. Gholam-Ali Hossein-Zadeh. Using fMRI data, modeling and simulations I studied the mechanisms underlying object-based attention in the human brain. My current postdoctoral fellowship is funded by the Alexander von Humboldt foundation from January 2024 to December 2025.


In my free time, I enjoy hiking, reading, listening to iranian traditional music, calligraphy and cooking.


Please see my CV for further information.

I am interested in studying the mechanisms based on which attention affects neural responses in the human brain. I have investigated the effects of attention on neural responses in the visual cortex with isolated and cluttered stimuli, using computational modeling to reveal the underlying mechanisms of attention. Currently, I focus on how attention affects neural responses over time and to what extent the neural mechanisms of attention are common across modalities. In this research, I use a combination of fMRI, EEG, multivariate pattern analysis, and computational modeling.


I plan to conduct two projects during my stay in the lab.


In project 1, I aim to examine the time course of visual attention. Since the effect of attention on neural responses has been reported to depend on the number of presented stimuli, I will examine its time course with both isolated and cluttered stimuli. To do this, I will conduct an EEG experiment with object stimuli. Participants either attend or ignore presented objects and perform a task on the cued objects. I will then compare different correlates of attention in different task conditions using time-resolved multivariate analyses.


In project 2, I will use an equivalent strategy to determine the time course of attention in the auditory system and compare the temporal dynamics of attention across the visual and auditory systems. I will present auditory words that are either attended or ignored based on the cue the participants receive. I will then investigate the time course of the attention component of the signal in different conditions to determine the relationship between the temporal dynamics of attention and the stimuli.


Finally, I will use the results obtained in the first two studies to computationally model the time course of attentional modulation in the visual and the auditory domains. I will use artificial neural networks and dynamic models based on neural studies to determine if a single model can account for the observed effects of attention on cortical responses in the visual and auditory cortices.
