I am a driven and accomplished researcher hailing from Medina, Saudi Arabia.  I am a Ph.D. in Bioscience program at King Abdullah University of Science and Technology (KAUST). Prior to  my doctoral studies, I earned a Master of Science in Bioinformatics and Molecular Biochemistry from George Washington University (GWU), USA.  I also completed my  Bachelor of Science in Chemistry at Taibah University, KSA.


Research Interests

In the STEMD lab,  I  channel  my research focus towards understanding the role of genetic overdosage in a multitude of physiological conditions. Specifically, I delve into investigating the repercussions on infertility, metabolic disorders, intellectual disabilities, osteoporosis, and cancer. I employ meticulously designed in vivo models of Klinefelter syndrome to conduct my  investigations, aiming to unravel the intricate gene-to-phenotype correlations and to identify the underlying transcriptional and epigenetic signatures that contribute to the manifestation of these human diseases.

Professional Profile

My  journey in scientific research began as an undergraduate researcher at Taibah University, where I synthesized and analyzed novel thio-1,2,4-triazole derivatives and screened them for their anti-fungal and anti-proliferative activity.

Then,  I  moved to the United States and joined Professor Alejandro Villagra’s lab as a graduate researcher at GW Cancer Center. Here, I showcased my  analytical prowess by investigating the role of Histone deacetylase inhibitors in the phagocytosis capacity and the Alteration of CD47/SIRPa Pathway in multiple human melanoma cell lines and monocytes derived macrophages.

Additionally,  I served as a Graduate Teaching Assistant in the Chemistry Department at GWU, where I imparted my knowledge in Organic Chemistry I lab and Medicinal Chemistry to undergraduate students.

After my graduation, I  moved on to serve as a Senior Research Assistant at The Li Lab in the Department of Biochemistry & Molecular Medicine at GWU. In this role, I investigated the mechanistic role of tumor DDR1 in the progress of Breast Cancer using CRISPR-Cas9; I oversaw the care and management of mice colonies and contributed to animal procedures. Moreover, I took on administrative responsibilities including, but not limited to, inventory and SAP budget management.
