Amin Saberi

Amin Saberi

PhD candidate, HIBALL

Amin studies the link between excitation-inhibition and cortical structure, and their development in typically developing adolescents and those at higher risk for psychopathology.

Sarah Sobotta

Sarah Sobotta

PhD candidate, IMPRS

Sarah is a PhD student with a background in neuroscience and social sciences. In her research, she aims to explore how social and environmental factors affect brain development.

Bin Wan

Bin Wan

Postdoc (bridge until defense)

Bin is studying asymmetry of brain organization. In parallel, he has wide interests in how the human mind (from behavior, ideology to brain circuits) is shaped by nature and nurture. Personal website.

Caroline Jantzen

Caroline Jantzen

PhD candidate, IMPRS

Caroline is physicist and studying brain dynamics. She is currently drafting her PhD proposal.

JiHoon Kim

JiHoon Kim

PhD candidate, IMPRS

JiHoon is studying the structure and function of the prefrontal cortex

Meike Hettwer

Meike Hettwer

Postdoc (bridge until defense)

Meike is a PhD student at Max Planck School of Cognition. Her work aims to understand how brain organization shapes resilience and vulnerability in mental health, in the larger context of transdiagnostic psychiatry and network-based pathology.

Neville Magielse

Neville Magielse

PhD candidate, HIBALL

Neville studies the cerebellum from different perspectives, by looking at cerebellar evolution and functional imaging.

Ekaterina Manoli

Katerina Manoli

PhD candidate, Studienstiftung

Katerina studies the role of the developing and adult cerebellum in social cognition, and more specifically in Theory of Mind. She focuses on structural and functional connectivity between the cerebellum and the cerebral cortex, as well as the effect of cerebellar maturation on the early-life emergence of Theory of Mind.

Bianca Serio

Bianca Serio

PhD candidate, School of Cognition

Bianca is a PhD student at the Max Planck School of Cognition. She studies sex differences and the effects of sex hormones on brain organization, with a particular interest in how these factors relate to emotion and affective disorders.

Alex John

Alex John

PhD candidate, IMPRS

Alex found her interest in the thalamus, its structural connectivity with the cortex, and its role of orchestrating whole-brain activity. Additionally, with her background in biology, she likes to think about how to translate macroscale findings at the systems-level to the biological underpinnings at the microscale.

Mylla Marsiglia

Mylla Marsiglia

PhD candidate, IMPRS

Mylla studies the hippocampus, with a focus on the effects of early life stress (i.e., adverse early life experiences and socioeconomic factors) on the development and functioning of the amygdala and hippocampus.

Deniz Yilmas

Deniz Yilmas

Student intern

Deniz is a student from the USA who is shadowing Bianca and working on sex hormones and the brain.

Clara Weber

Clara Weber

MD postdoc

Clara is an MD and working on the perinatal period to understand emergence of neurodevelopmental disorder.

Yiğit Eriguc

Yiğit Eriguc

PhD candidate, IMPRS

Yiğit is a PhD student at IMPRS CoNI that comes from a psychology/cognitive neuroscience background. He is interested in the relation between cognition and large-scale brain organisation.

Huantao Wen

Huantao Wen

PhD candidate

Huantao is a PhD candidate who comes from a background in clinical medicine. He just started his PhD in the lab and is particularly interested in the brain structural, functional and biomarkers organizational patterns during pathological status, and their relation with clinical symptoms and outcomes.

Jessica Royer

Jessica Royer

guest postdoc

Jessica is a clinical psychologist by training and works on a project trying to understand the brain basis of social cognition.

Sofie Valk

Sofie Valk

Research group leader

Sofie is Lise Meitner research group leader at the MPI in Leipzig, Germany and research group leader at INM-7 Juelich, Juelich, Germany. She is also a Jacobs foundation research fellow.

Satellites and affiliated members

Lars Dinkelbach

Lars Dinkelbach

clinician scientist

Lars is a developmental neuroendocrinologist and a clinician scientist.

Yun Shuang Fan

Yun Shuang Fan

Professor

Yun Shuang was visiting the lab through the Chinese State-Sponsored Scholarship for joint PhD students program. She works on various projects bridging brain organization and Schizophrenia.

Giacomo Bignardi

Giacomo Bignardi

PhD guest, School of Cognition

Giaco(mo) was born in the humanities but was raised by scientists. All grown up, he is trying to accept both past, pursuing a PhD on the biological basis of aesthetics with the Max Planck School of Cognition at the Language and Genetics Department of the MPI for psycholinguistics, in Nijmegen, while being a nomadic guest of the Frankfurt and Leipzig MPIs.

Benjamin Hanisch

Benjamin Hanisch

affiliated clinician scientist

Ben studies neurotransmitters/receptors and their link to hallmarks of brain function and disease, hoping to better understand the genesis and treatment of psychiatric illnesses.

Elham Gholamzadeh

Elham Gholamzadeh

PhD guest

Elham currently works with Nico Scherf and is currently guest in our lab.

Şeyma Bayrak

Şeyma Bayrak

MD and affiliated clinician scientist

Şeyma studies the functional and structural organisation of the human brain. She loves big data and computational challenges and recently the functional neurosurgery.
