Elif Aysimi Duman


Principal Investigator

Elif Aysimi Duman is a biopsychologist, conducting research mainly on gene-environment interactions related to individual differences in social behavior. She received her undergraduate degree in Molecular Biology and Genetics from Istanbul Technical University, followed by taking a year of psychology courses at Bogazici University. She then completed her Ph.D. in Biopsychology at Stony Brook University, New York. In her dissertation, she investigated how early life stress and a genetic variation in the serotonergic system interacts to influence differences in DNA methylation, gene expression and cortisol response. Since 2012, she is working as an Assistant Professor at the Psychology Department of Bogazici University, conducting research in the Psychoepigenetics Lab with students from various disciplines, combining psychological, genetic and epigenetic research approaches to understand individual differences in behavior.

Gizem Dedeoğlu

Graduate Student

B.Sc. Molecular Biology and Genetics, 2014, Bogazici University

Gizem has received her undergraduate degree in Molecular Biology and Genetics from Bogazici University in 2014 and continues her education in Psychobiology in Bogazici University under supervision of Asst. Prof. Elif Duman. Her research interests involves effects of sleep and stress on awakening cortisol of participants; as well as genetic and environmental factors of depression and their interaction. She has worked in a project of Peg Lab investigating gene environment interaction of undergraduate students in 2014 and would work in continuum of the project. She is also actively working in one of the Peg Lab projects investigating childcare chaos and its interaction with HPA-axis activation and DNA methylation. She is the laboratory assistant of two Psychobiology laboratories including Peg Lab and responsible from conducting experiments and management of the laboratories.

Alev Ecevitoğlu

Graduate Student

B.Sc. Molecular Biology and Genetics, 2016, Bogazici University

When Alev was senior in Molecular Biology and Genetics, she was already an intern in the psychobiology laboratories  in Bogazici University; and helped with the ongoing project about Cortisol Awaking Response. After her graduation, she started as a graduate student in Psychobiology field again in Bogazici University. She also participated in Erasmus programme in Biosciences field, at Kent University England. She's interested in stress, depression and psychopathological disorders with relation to their genetic background and especially DNA methylation status. Also, she is questioning how gene-environment interactions are affecting depression and behaviour. Besides, she likes dancing, scuba diving, playing video games and drawing in her spare time.

Kardelen Canan Ergin

Graduate Student

B.Sc. Chemistry, 2014, Bogazici University

After receiving her undergraduate degree from Chemistry, Boğaziçi University 2014, she is continuing her education in Psychobiology as a master’s student. While her academic interests include attention deficit hyperactivity disorder (ADHD) and sleep, her personal interests also include time perception, gaming, autism spectrum disorder, and learning disorders. She is in charge of the psychology part of our psychoepigenetics laboratory. Briefly her responsibilities are behavioral paradigm training, scheduling and keeping track of experimental sessions, workload follow-up and data entry.
In her spare time she enjoys reading e-books, making cross-stitch patterns, playing PC games and rollerblading.

Rezan Nehir Mavioğlu

Graduate student

B.Sc. Molecular Biology and Genetics, 2015, Bogazici University 

Nehir received her BSc degree in Molecular Biology and Genetics (MBG) from Boğaziçi University (2015), and she is currently a master student in our lab. During her bachelor studies, apart from her work in our lab, she worked with Dr. Aslı Tolun from MBG department and investigated the genes responsible from some rare neurological diseases. She also worked as an intern in Vrije University Amsterdam with Dr. Meike Bartels about heritability of optimism in adolescent twins, and in University of Würzburg with Dr. Klaus-Peter Lesch’s team in the effects of fear conditioning in Tph2 knockouts, and effects of some drugs on neurogenesis in mice.

She is curious about how and why individual differences in human behavior occur. She is currently interested in gene-environment interactions in stress-related behavior, and underlying epigenetic mechanisms. In her spare time, she enjoys spending time with her cat, cooking and reading.
