Dr. Çağdaş Devrim SON is a Professor in the Department of Biological Sciences at Middle East Technical University. During his undergraduate and postgraduate studies at METU, his interest in molecular biology, biochemistry, organic chemistry and microbiology has led to his work in structural biology. During PhD studies, he worked on the interaction of peptide ligands with G protein-coupled receptors (GPCRs). During these studies, he has gained experience in many molecular and biochemical techniques such as western blot, chemical and photoactive cross-linking, mass spectrometry, site directed mutagenesis and fluorescence microscopy. He continued his post-doctoral studies at the University of Tennessee and California Institute of Technology for over four years, working on protein-protein interactions and analysis of these interactions. During this time he intensified his work on new methods to understand the interactions of cell membrane proteins with each other, with other proteins and with small peptide ligands.

In 2009 he start working at Middle East Technical University, currently his work focuses on the identification of motifs that play important roles in protein-protein interactions by applying rapidly developing fluorescence microscopy, bioinformatics and computational biology techniques.

Tolgahan Suat SEZEN

Tolgahan Suat SEZEN

PhD Student

Biochemistry

tolgahan.sezen@metu.edu.tr

He was sophisticated with a heavy emphasis on cellular biology, genetics, and biochemistry. He studied both Molecular Biology and Genetics and Chemistry at Middle East Technical University (METU). Then, he studied Chemistry and Life Sciences Master of Science program at both Paris Science and Lettres (PSL) and Sorbonne University in Paris. Throughout his education, he has studied on β2-Adrenergic receptor (β2AR) regulation by β-Arrestin-2, mechanistic study on autophagy for cellular aging and cancer, lncRNA-protein interaction which leads to cellular stress responses, Rloop dynamics in dosage compensation and RNA splicing, and now, G-protein interactions and KRas dimerization as a part of his PhD study. His Master’s studies have reinforced his interest in integrating not only chemistry but also positive sciences into biology with an interdisciplinary understanding. His primary motivation is improving himself, not only by answering but also raising proper questions.

Biochemistry

zubeyir.nursoy@metu.edu.tr

Zübeyir is a versatile researcher pursuing a Master's in Biochemistry, specializing in fullerenol derivatives for BBB-crossing drug delivery, neuroimaging, and enzyme mimicry. With Bachelor's degrees in Molecular Biology and Genetics (with a minor in Mechatronics) and Mechanical Engineering, he integrates biology, chemistry, and engineering. As a researcher in METU's labs, he functionalizes nanoparticles, conducts cytotoxicity assays, evaluates neuroprotective effects, and develops automated FRET pipelines for molecular interaction analysis using confocal microscopy and programming tools like Python. He has volunteered in STEM education and presented at international conferences. You can find him tinkering with the microscope in the lab — if not, he’s most probably in the library at the Kasım Gülek Collection, indulging in old books.

MSc Student

Molecular Biology and Genetics

betul.yiyen@metu.edu.tr

Betül graduated from Middle East Technical University with a degree in Molecular Biology and Genetics in 2023. Following her graduation, she began her Master’s studies in the Son lab. Her research interests focus on the molecular mechanisms of cell signaling, particularly the role of protein-protein interactions in regulating downstream pathways. During her undergraduate and graduate projects, she worked with heterotrimeric G proteins and Kras, investigating how dimerization events influence MAPK and PI3K/AKT signaling cascades. To explore these interactions, she employs molecular cloning, qPCR, and Western blotting.

She is particularly interested in how disruptions in these interactions affect signaling bias, with the long-term goal of identifying molecular targets for therapeutic intervention. Beyond the lab, she enjoys cycling, baking, and dancing.

Soha Wasim completed her undergraduate studies in Molecular Biology and Genetics at Bilkent University in 2022. She began her graduate studies at METU in 2023, continuing in the same department.

Since joining Son Lab, she has been working on projects involving the interactions between Kras and heterotrimeric G-alpha proteins. Currently, she is investigating the heterodimerization of point-mutated Gnai1 with dimerization-deficient Kras protein. She employs molecular cloning methods, confocal imaging, and FRET.

By mutating critical residues on Gnai1, she aims to create a set-up in which mutant KRas, which is homodimerization-deficient, is made to heterodimerize with Gnai1. Her hobbies outside the lab include weight-training at the gym, creative writing, and dancing.
