Dr. Ehsan Pourkarimi D

Principle investigator

Assistant Professor in Genomics and Precision Medicine

Dr. Ehsan Pourkarimi, did his undergraduate study at ELTE university in Budapest, Hungary. After receiving a Cancer Research UK fellowship, he moved to the United Kingdom. He joined the Lab of Prof. Anton Gartner in the Wellcome Trust Center for Gene Regulation and Expression at the University of Dundee. During his Ph.D., Dr. Pourkarimi characterized the key components of the core apoptosis machinery in C. elegans and challenged the well-accepted model of apoptosis induction. Focused on chromatin biology, his post-doctoral research delved into the effect of chromatin modifiers in cellular response during acute stress conditions. Using the SILAC-based proteomics approach, Dr. Pourkarimi demonstrated the significance of Histone H3.3 variants in aging and also during acute starvation. As a Research Associate in the Lab of Dr. Iestyn Whitehouse at Memorial Sloan Kettering Cancer Center in New York City, Dr. Pourkarimi studied DNA replication.

Using C. elegans embryos, he mapped DNA replication origins, creating the first comprehensive map of DNA replication from a multicellular organism. In 2020 he moved to Qatar as principal investigator and assistant professor in Genomics and Precision Medicine (GPM) and established his research lab in Qatar. His Lab uses cutting-edge technology such as epigenome editing to tackle the fundamental question in chromatin biology, from DNA damage response to understanding the mechanism of epigenetic memory.

Upon his graduation and working a few years as a research assistant at Royan institute, he joined our Lab in 2020 to pursue his Ph.D. studies in Genomics and Precision Medicine. His current Ph.D. project is to identify novel players of DNA damage response in C. elegans. He also models various human disease-causing mutations in the model system to understand their biological relevance in human health and diseases.

Farah Shurrab

PhD Student

Farah is a PhD student in Genomics and Translational Medicine at Hamad Bin Khalifa University (HBKU), conducting her research in Dr. Ehsan Pourkarimi’s lab.

Her research focuses on DNA damage and the DNA damage response (DDR), using the model organism C. elegans to explore the role of proteins involved in DDR. By leveraging translational model systems, she aims to bridge the gap between basic scientific research and clinical application, advancing our understanding of DNA damage and repair and its impact on human health.

Raheleh Vazehan

PhD Student

Raheleh completed her BSc in Cellular and Molecular Biology-Genetics at the Tehran Azad University and received her MSc in Genetics of Human Disease from University College London (UCL). She has worked as a clinical NGS data analyst at a clinical genetics laboratory, and she is currently doing her PhD in Genomics and Precision Medicine at Hamad Bin Khalifa University (HBKU). Raheleh has recently joined Pourkarimi lab, and she will be employing mass spectrometry-based proteomics to study the DNA damage‐induced changes in protein interactions, protein abundance, and post-transcriptional modifications in C. elegans.

Zainalabedin Alrayyes

PhD Student

Zainalabedin completed a Bachelor of Science in Molecular Biology and Genetics at Eastern Mediterranean University in Cyprus.

Following graduation, he worked as a Genetics Assistant at the Genetic Diagnosis Unit of Al-Basma IVF Centre in Palestine, where he gained hands-on experience in genetic diagnostics.

In 2019, Zainalabedin received the prestigious Ireland Palestine Scholarship Programme, where he earned his Master of Science in Diagnostics and Precision Medicine from Dublin City University, Ireland. For his MSc research project, he conducted an in-silico study titled "Prediction of Survival of PDAC Patients from a Signature of DDR Genes in Response to G4 Ligands." This project included a comprehensive review of G-Quadruplex Ligands in cancer therapy and resulted in identifying a unique multi-gene classifier based on DDR genes differentially expressed in response to G4 ligands.

Subsequently, Zainalabedin served as a Health Projects Coordinator at CCP-Japan NGO for two years, further broadening his expertise.

In 2023, he joined Hamad Bin Khalifa University (HBKU) and the Pourkarimi Lab as a GPM PhD student. His research focuses on understanding the role of chromatin remodelers in DNA damage response and apoptosis.

Alanoud Al-Kaabi

PhD Student

Alanoud obtained her Bachelor’s degree in Biological Sciences from Qatar University. In 2017, she joined the Anti-Doping Lab Qatar, where she gained valuable experience in both clinical and analytical laboratory techniques. During her time there, she worked across two departments: liquid chromatography-mass spectrometry (LC-MS) and the biological section, acquiring hands-on experience in a variety of analytical and molecular techniques.

She later joined the Pourkarimi Lab at Hamad Bin Khalifa University (HBKU) to pursue a Master’s degree in Biological and Biomedical Sciences. Her thesis focused on investigating the pro-apoptotic effects of the anticancer drug Thiostrepton using Caenorhabditis elegans as an in vivo model. She combined genetic and drug-based approaches with imaging tools to study cellular responses in C. elegans. The project, conducted in collaboration with Hamad Medical Corporation (HMC), provided insights into the drug’s mechanism of action, particularly its role in apoptosis induction.

Alanoud is currently a Ph.D. student in the Biological and Biomedical Sciences program at HBKU and has rejoined the Pourkarimi Lab to continue her research on chromatin remodeling and cellular stress responses.

Maryam Al-mansoob

PhD Student

Maryam earned her Bachelor’s degree in Biological Sciences with a minor in Chemistry from Qatar University. She completed a research internship at Weill Cornell Medicine and went on to pursue a Master’s in Biological and Biomedical Sciences at Hamad Bin Khalifa University (HBKU). During her Master’s, she joined Pourkarimi’s lab, where she investigated the role of WARS1 in the cell cycle and DNA repair using genomics approaches—a project recognized with funding from the prestigious Qatar National Research Fund (QNRF).

Maryam has now returned to the lab as a PhD student, where her research focuses on unraveling novel components of the DNA damage repair pathway.

Dr. Abeer Jamal

Visiting PhD Student

Dr. Abeer is a Ph.D. student of the Genomics and Precision Medicine program at HBKU. She works at Dr. Nady and Dr. Ehsan's lab to pursue her P.hD. research project. Abeer is interested in using C.elegans as an animal model for studying aging-related human disorders. The first aging-related gene, associated with the genetic regulation of life span has been identified in C elegans. That made Abeer excited to join our lab to functionally characterize her candidate genes using our models' system. C.elegans has been frequently utilized as an ideal living system for aging studies due to their small body size, short lifespan, and homologs of about two-thirds of all human disease-causing genes. Currently, she is humanizing C. elegans to identify how the overexpression of her gene of interest can affect C.elegans lifespan. She leads a collaborative project with our lab and Nady's at HBKU.
