I am a Research Academic at the Priority Research Centre for Bioinformatics, Biomarker Discovery and Information-Based Medicine (CIBM), University of Newcastle. I have graduated with a PhD in Computer Science from the University of Newcastle in 2013. Prior to that I completed my MSc in Information and Communication Technology from the Institute of Information and Communication Technology, Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 2008. My areas of research expertise include: graph based data mining, network analysis, high performance computing (HPC), GPU-based computing, and bioinformatics. For a more detailed description of my recent research and software codes, please refer to: http://www.ahmedshamsularefin.id.au.</p>

My current research stand point is at the intersection of graph based data mining and high performance/ distributed computing. I am also fascinated by network analysis (including social networks) and I aim to incorporate parallel data mining in network analysis. During my PhD research, I worked with a set of GPU-based methods for constructing minimum spanning trees and k-nearest neighbor graphs (GPU-FS-kNN, PLoS ONE 7(8): e44000), and an external memory-based highly scalable data clustering method for clustering large data sets. The methods guided to uncover some important genes from a well-known breast cancer microarray study. Furthermore, in a different application, it helped to identify a small number (out of a relatively large molecular signature) of transcripts recurrently clustering with different markers of Alzheimer’s disease progression.
I also worked with graph theory. During my MSc. research, I proved that the minimum edge-ranking spanning tree (MERST) problem for general Series-Parallel (SP) graphs is NP-Complete and designed an efficient approximation algorithm which gives a near-optimal solution for the problem. The MERST problem of graphs has important applications such as scheduling the parallel assembly of a complex multi-part product from its components and relational databases.
In short, I do a great deal work and research in big data, data mining, clustering, graphs and visualization. I am an enthusiastic computer programmer with demonstrated abilities in C++, Java, C#, Python, R, OpenMP, MPI and CUDA based application developments.

I completed two teaching related qualifications: ‘Professional Certificate Course in University Assessment’ and ‘Fundamentals in University Teaching Certificate’ from the Center for Teaching and Learning (CTL), University of Newcastle, Australia in 2014. Further in July 2013, I participated in a 'Sessional Academic Development Workshop', offered by the CTL, University of Newcastle. I am also completing a 'Post Graduate Certificate in Higher Education' (with specialization in Teaching and Learning), from the Macquarie University, Sydney, Australia.
I have taught/tutored the following units at the School of EECS, FEBE, University of Newcastle, Australia:
- SENG 1120 Introduction to Software Engineering II (Semester 2, 2013)
- SENG 1110 Introduction to Software Engineering I (Semester 1, 2013)
- SENG 2130 Software Development, (Semester 1, 2012)
- COMP 2240 Operating Systems, (Semester 2, 2011)
Furthermore, I performed the following programming contest related (extra-curricular) activities in my discipline:
- Coached one of the University of Newcastle ACM-ICPC teams ("UoN Stu and Arts") for participating in the 2013 South Pacific Regional Contest, Sept. 21, 2013 (University of Sydney Site).
- Worked as a trainer for the first University of Newcastle ACM-ICPC teams for participating the 2012 South Pacific Regional Contest, 2012 (University of Sydney Site).
I also worked as a successful programming contest problem setter, judge and organizer for local and international contests (e.g., University of Valladolid (UVa) online contests, problem numbers: 10219-10222).
