  • MSc. in Biotechnology (2010- 2011) School of Chemical Engineering and Analytical Science, The University of Manchester, United Kingdom.
  • BSc. in Biochemistry (2005- 2008) King Abdul-Aziz University, Saudi Arabia.

I am currently pursuing a PhD in Biotechnology in the School of Chemistry, and working in the Surface Analysis Research Centre (SARC). My research interests include imaging of biological samples using Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS).

My research is focused on investigating the quantitative and qualitative effects of varying the ion beam sources and sample preparation methods on the SIMS response. Biological samples are studied including heterogeneous mixture samples of amino acids, lipids and drugs in addition to single cells’ imaging.
