About me

I did my PhD at the faculty of Computing and Engineering at the University of Ulster in Northern Ireland, UK. My PhD’s focus was on strengthening steganography in digital images. My thesis, completed in 2009, was a worthwhile contribution to knowledge in the subject area and also produced two successful international patent applications. I have in records 21 international, peer reviewed, Journal papers, 27 peer reviewed international conference papers, 3 patents, a book and a book chapter (invited). I was awarded a research grant from University of Ulster’s Innovation centre worth £7,430 and Invest NI & European Regional Development Fund worth £77074.20.

My research interests lie at the intersection of Image processing, Computer vision, Information security, Medical sciences and biology (e.g., 3D reconstruction, Optical projection tomography, Steganography, Medical image analysis, Quantitative imaging bio-markers, Pattern localisation and recognition, Characterization and validation of imaging bio-markers, Evaluation of the association between image-based phenotypes and genomic biomarkers, Algorithms for the computer-guided analysis of multi-dimensional microscopy-data sets), Computational support for tissue-related target/ biomarker discovery, development and analysis.

At BTH, I am participating in a large research project, “Scalable resource-efficient systems for big data analytics”, where close research collaboration with industry is key for the project execution. I will invest my expertise in image processing into rather a larger project that focuses on Big Data, for more info Click here . More specifically, I will be working on Research theme B: Big data analytics for image processing. The research profile, Scalable resource-efficient systems for big data analytics, combines existing expertise in machine learning, data mining, and computer engineering to create new knowledge in the area of scalable resource-efficient systems for big data analytics. The value of the new knowledge will be demonstrated and evaluated in two application areas (decision support systems and image processing).

Reviewer's comment: "This manuscript presents an interesting and novel approach to enhance mammographic density assessment from 2-dimensional images. It has been long been considered a weakness that the common assessment methods using film mammograms ignore the third dimension of breast thickness. Therefore, this paper makes a new contribution to the field of mammographic density research..."
