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.

After obtaining my Bachelor’s degree in Molecular Life Sciences at Radboud University, I completed the research Master’s in Molecular Mechanisms of Disease at Radboudumc.  I performed an internship at the department of Radiotherapy & Oncoimmunology in Radboudumc where I studied the reprogramming of tumor-associated myeloid cells with a focus on lipid metabolism. In my second internship I worked on the identification of T cell migration regulators in solid tumors at the German Cancer Research Center in Heidelberg, Germany.  In December 2021, I joined the Akkari lab as a research technician. Here I will be investigating the use of pro-senescence therapy in liver cancer and its effects on the liver tumor microenvironment.

I studied Biomedical engineering at the Carlos III University of Madrid. There, I worked at the bioengineering department building a bioinformatics tool to asses genotypic-phenotypic relationships within the Gene Ontology framework. After that, I moved to Amsterdam to do a MSc in Bioinformatics and Systems Biology, a joint master between VU and UvA. During my first internship, worked for 6 months at the artificial intelligence group of the NKI’s radiology department. I worked in a radiogenomics project to find relationships between PET images and mutational status of genes under the supervision of Zuhir Bodalal and Stefano Trebeschi. Now, for my second master internship I moved to the Leila Akkari group to work under the supervision of Masami Ando Kuri. The project makes use of scRNA-seq and spatial transcriptomics data and is aimed to understand how tumor-associated macrophages interact with the tumor and its micro-environment.
