Role and responsibilities within the QRC-PVD:

Currently, I lead one of the preclinical team within the QRC-PVD with a special focus on development and use of preclinical models of blocked arteries (peripheral arterial diseases; PAD) and weakened arteries (abdominal aortic aneurysms; AAA). Translational research involves applying insights and discoveries generated by basic scientific inquiry for the treatment or prevention of human diseases. The long-term objective of the translational research program in the QRC-PVD is to develop new treatments for PAD and AAA. One of the limitations of preclinical work is the lack of appropriate pre-clinical models covering important aspects of the human disease. To address this problem, one focus of the research within the QRC-PVD has been examining the clinical relevance of pre-clinical models. The models currently being assessed within the QRC-PVD include various models of AAA, lower limb ischemia and stroke.

I am also involved in the QRC-PVD Management and Biobank Sample committees to facilitate goal oriented progress of the team. I currently co-supervise 4 PhD students that are working on the topics of therapeutic revascularisation in lower limb ischemia and nutritional intervention in AAA. I invite expressions of interest from capable and committed prospective students interested in becoming involved in peripheral artery research.

I was awarded a PhD in 2006 in Cancer Biology from the Laboratory of Tumour Immunology and Functional Genomics in Regional Cancer Centre, India. The project focused on the viral and environmental interaction of various cell-cycle regulatory proteins which lead to cancer. The work identified crucial molecular pathways which are affected by the DNA virus infection and the relation to the response of the patients to anti-cancer therapy. I did my Postdoctoral research in the Immunology Department in the Faculty of Medicine & Health Sciences in UAE University and worked for 3 years in the Molecular Biology & Genetics Laboratory under the Dubai Government as a Senior Research Scientist. My work mainly focused on analysis of gene expression patterns and epigenetic silencing of genes under physiological and environmental stress. The research involved sophisticated molecular biology techniques including development of cDNA libraries, BAC libraries, SNP analysis and microarray analysis. I joined the QRC-PVD in 2009 and continued researching on the genetic and epigenetic alterations leading to the development of PAD.

Research/projects:

My primary interest is translational research aimed at better understanding the molecular and cellular mechanisms involved in development and progression of PAD and AAA.

Specific interests include:

1. Developing and refining Preclinical models of PAD and AAA.

2. Testing therapeutic interventions in preclinical models;

3. Genetic and epigenetic alterations in the pathology of PAD and AAA.
