Bio

Alya A. Arabi is an Assistant Professor of Chemistry at Zayed University, UAE.  She received her PhD in Chemistry from Dalhousie University, Canada in 2012.  Prior to starting her graduate studies, in 2008, Alya was awarded a Bachelor of Sciences Honours degree with highest aggregate in 2008 from Mount Saint Vincent University, Canada. Alya is the recipient of prestigious academic awards including the Killam Predoctoral Scholarship (2008-2010), Alexander Graham Bell Canada Graduate Scholarship (2008-2009), and Natural Sciences and Engineering Research Council Graduate Scholarship-Doctoral (2009-2012). In 2012, Alya was lecturer at Mount Saint Vincent University in Canada. She then moved to the United Arab Emirates (UAE) to accept in February 2013 an adjunct faculty position at Abu Dhabi University for one year. In March 2014, she joined the College of Natural and Health Sciences at Zayed University, UAE. Alya’s research interests lie in the investigation of chemical and biochemical systems using computational tools.

Research and Professional Activities

 

My research interests, as computational chemist, focus on the investigation of chemical and biological systems using electronic structure methods and Quantum Theory of Atoms in Molecules. I have worked on characterizing, at an atomic scale, the homolytic cleavage of a phosphate group and the heterolytic cleavage of an adenosine 5’-triphosphate (ATP) model. ATP is the energy currency of all living cells, and the objective was to nail down the atomic source of this energy in phosphate bonds.

I have also studied the effect of high electric fields on the double proton transfer (DPT) in base pairs of the genetic code carrier, DNA. DPT is a reaction that is believed to cause point mutations in the DNA, and subsequently carcinogenic tumors. The results were that DPT rate increases by a factor of four in the presence of high homogeneous electric fields. This project is currently being extended to study the effect of intercalating molecule in DNA base pairs.

Another topic of interest is the investigation of bioisosteres, which are functional groups that can be interchangeably used to enhance some properties of pharmaceutical drugs without affecting their biological activity. The purpose of this project is to uncover the reason why bioisosteres function the way they do. These isosteres were found to have identical average electron densities and overlapping electrostatic potentials. I am currently extending this research idea to a larger set of bioisosteres.

I am also collaborating with other groups on three topics related to cardiovascular diseases as a result of diabetes, stereochemistry of organic molecules and heavy metal contaminations in the UAE.
