My scientific interests on understanding the external cues regulating cancer malignancy stem from early on in my scientific training, with the realization that despite the groundbreaking discoveries of oncogenes and tumor suppressors, effective therapeutic options are still limited. That is because tumor progression relies on more than genomic alterations, and cancers evolve within a complex tissue microenvironment. Thus, to impact therapeutic outcome, our understanding of cancer dynamics and diversity must not solely view cancer cells as the fundamental unit, but as part of an integrated and reactive system centered around heterotypic communication with their environment. To understand tissue-level complexity, I have sought to diversify my skills and expertise throughout my training in an effort to determine the multifactorial cues that underlie tumor behavior. I come from a diverse and multidisciplinary scientific background that ranges from immunology and parasitology, to virology and cancer biology. My personal background is also quite diverse, with roots in Africa and the Middle East, and I have lived in the south of France, England, New York City, Switzerland and now Amsterdam. During these experiences, I have enjoyed meeting new friends, discovering different life styles and culture, and learning how to Zumba!

After completing a Bachelor in Human Movement Sciences and a Premaster in Biomedical Sciences, I obtained my Master’s degree in Oncology in 2016 at the VU University in Amsterdam. During this Master, I performed two internships. During the first one, at the division of Oncogenetics, VUmc and Cancer Center Amsterdam, I studied the regulation of sister chromatid cohesion. After that, I went to the group of Dr. Michele Pagano at the New York University Medical Center, where I investigated the role of cyclin F in protein degradation. In March 2017, I started my PhD in the Akkari lab at the Netherlands Cancer Institute, where I work on the dynamic roles of innate immune cells in brain tumor resistance and recurrence post-therapy.Next to working at the NKI, I like spending time on my hobbies. I’ve been playing saxophone and guitar for many years, ranging from jazz to classical music. In addition, I like many different sports, especially soccer, and enjoy photography as well.

I graduated from the Department of Genetics and Bioinformatics at Bahcesehir University, Turkey. After completing my undergraduate studies, I obtained my master’s degree in Molecular Biology and Genetics at Middle East Technical University, Turkey. In my thesis study, I analyzed the transcriptomic profiles of bacilysin biosynthetic operon silenced mutant of Bacillus subtilis and its parental strain. After my first encounter with immunology during my master’s, it was clear to me that I wanted to continue my academic career in tumor immunology as I developed a strong interest in potential ways to improve current methods of treatment. I joined Dr. Leila Akkari’s research group in October 2022 to investigate the interplay between glioblastoma cells and tumor microenvironment in response to therapy, particularly in the context of tumor-associated macrophages.

During my Master’s degree in Biomedical Sciences I chose to specialize in Oncology. I conducted my first internship in the group of Dr. Jeroen Guikema at the AMC where I investigated the role of proteotoxic stress in therapy response in Multiple Myeloma. For my second internship I joined the group of Dr. Leila Akkari where I worked on non-alcoholic steatohepatitis (NASH) associated Hepatocellular Carcinoma. Here, I investigated the role of different macrophage populations in the progression of NASH with the goal of identifying novel treatment approaches involving metabolic modulation. In November 2022, I then started as research technician where I continue working on this project while also getting involved in the Glioblastoma research theme of the lab.

I graduated with my bachelor’s degree from the University of Applied Sciences in Leiden in 2024. During my studies, I fell in love with the immune system, with the dendritic cell being my (slightly controversial) favourite immune cell.

This didn’t stop me from applying for an internship at the Akkari Lab, where macrophages take centre stage. During my internship, I worked on the impact of pro-senescence therapies on the tumour microenvironment in hepatocellular carcinoma, a project I very much enjoyed. Funnily enough, my favourite organ is the liver, so it turned out to be a perfect match.

I have since returned as a technician, with murine models as my main area of expertise. I still work on the project I interned on, but I am now involved in several others as well. Working on many different projects has brought me a lot of new knowledge and joy.

Outside the lab, I enjoy crafting (some of which can be spotted around the lab), lifeguarding, hiking and skiing, usually at slightly too high speeds.
