︎In a nutshell
Starting with clinical/abnormal psychology, I slowly found a thing for neurobiological mechanisms underlying behavior and cognition. So I started my graduate studies in neuroscience, aiming to be a cognitive neuroscientist. But I started learning about animal behaviors, biological complexity, and so-called “wet neuroscience”. During that time, I realized how weird animals are (seriously tho, aren’t they?) and got attracted to evolutionary perspectives and the beauty of behaviors themselves. Thinking about giving up on human brains and sticking to rats or something, I was introduced to computational neuroscience. Well, my promiscuous attention span couldn’t say no to that either. A couple of seminal papers later, I finally settled on being interested in the neural network models of cognition and behavior. Of course, I still love reading and thinking about neuronal underpinnings of psychiatric disorders and animal behaviors, but now we’re just very good friends who hang out sometimes.

I study the brain-behavior relationship. I want to “understand the brain” by quantifying how much its elements - neural circuits and brain regions - are causally relevant for its function. I use systematic lesioning to quantify elements’ contributions, and since large-scale experimental lesions are infeasible, I use artificial neural network models as toy models of brains. The goal is to see how much information about networks’ inner mechanisms can be gained by decomposing them into pieces and naturally, how to effectively use the results to guide in-vivo experiments.
MSc Neuroscience @Carl von Ossietzky University of Oldenburg.October 2016 - September 2018
The focus of my program was on “Sensory systems” on multiple levels. I had different courses from cognitive neuroscience, to behavioral ecology, neurophysiology, and statistical learning. I joined the Biological Psychology Lab in 2017 and had my thesis on the Cocktail party effect using fMRI.
BSc Clinical Psychology @Roudehen Azad University of Tehran.October 2009 - December 2015
I studied the biological foundations of mental disorders, diagnosis, nosology, clinical interview, basic statistics, and seminal theories in psychology. I had my thesis on inducing agitation and a sense of presence using music. The idea was to find core components of the soundtracks from horror movies. It didn’t really work.
Teacher Assistant @Neuromatch AcademyJuly 2020
Neuromatch Academy is an online school of computational neuroscience during the lockdown due to the Corona pandemic. I was a TA there, learning a lot and finding very nice friends.
Research Fellow @Zatorre lab, McGill University, Montreal Neurological Institute.July 2018 - September 2018
For my MSc thesis, I studied auditory attention in a complex environment (cocktail-party effect) using fMRI and analyzed the data using Inter-Subject Correlation (ISC). I was supervised by Dr. Sebastian Puschmann, Dr. Mor Regev, Prof. Dr. Christiane Thiel, and Dr. Robert Zatorre.
Research Fellow @Basal Ganglia, Motivation and Reward lab, Timone Institute of Neuroscience.October 2017 - April 2018
I studied the role of the hyperdirect pathway in the motivation for reward and cocaine for my MSc research project. I learned how to handle rodents, perform stereotaxic surgeries, implant catheters, and used chemogenetics to target the hyperdirect pathway. I was supervised by Dr. Christelle Baunez, Dr. Alix Tiran Cappello, and Dr. Jannis Hildebrandt.
Research Assistant @School of Cognitive Sciences, Institute for Research in Fundamental Sciences.August 2015 - October 2016
I was involved in two projects, one about the role of Oxytocin in human observational learning and the other about the network differences between patients with ADHD and control subjects. I was supervised by Dr. Hossein Vahabie.

Co-organizer and co-chair of the symposium “Modeling large-scale brain networks and their disconnection in neurological disorders” @DGKNMarch 2023
Mariia Popova and I organized this symposium, which was about the prominent role of large-scale brain network models in providing mechanistic understanding of complex dynamical processes underlying brain-behavior relationships in health and disease.
Co-organizer and co-chair of the symposium “Searching for Causes and Mechanisms in the Brain ” @ICNSDec 2022
Mariia Popova, Claus Hilgetag and I organized this hybrid symposium on the notion of causality and mechanism in neuroscience. We invited philosophers and neuroscientists to discuss their works and try to address the gap in these fields. Read more here, and have a look at the presentations in our YouTube channel.
Co-organizer of the Science Communication Workshop @Interdisciplinary CollegeMarch 2022
With Jens-Steffen Scherer and Valerie Vaquet, we organized a four-sessions workshop on science communication. I was mainly responsible for the session “visual communication” in which I presented methods to translate processes into simple visual diagrams.
Organizer of the Visual Communication Workshop @Institute of Neuroscience, Carl von Ossietzky University of OldenburgJune 2018
I organized and tutored a workshop on visual communication for the interested students. We discussed effective data visualization and how to use simple principles of design to have better figures.
