Dr Bonnie Law

Dr Law’s research interests include wavelet transform, image enhancement and retrieval. Recently, she has extended her study into new areas on bioinformatics and image forensics. The former involves works on gene expression and DNA sequence analysis while the latter considers source camera identification. Novel results for gene expression data analysis, biclusters detection and source identification have been achieved and published in international journals with good attention from peers, for example a paper in 2008 has been classified as a “highly access” article in BMC Bioinformatics journal (with the number of accesses of 6310 up to 7 Oct 2016).

Research Highlights:

Dr Law’s main research focus includes signal processing, DNA sequence analysis and source camera identification. Digital data has been abundant. Its source will be important in forensics analysis which can help in copyright identification or crime investigation. Dr Law and her group have worked on using various signal processing techniques for reliably identification of the source camera from a photo. In DNA sequence analysis, Dr Law worked actively on multiple DNA sequences compression in which a group of sequences are grouped and compressed simultaneously. Greedy methods have been developed to search for similarities within a group of sequences. Details regarding the greedy method and the software can be found at https://www.eie.polyu.edu.hk/~nflaw/RCC/index.html.
