Project Description

There are many bioinformatics datasets available publically. Extracting consistent information from these require development of novel techniques and tools. This has many applications in medical (and biological) fields with direct consequences for developing drugs, helping doctors to deliver services, and finally curing patients.
Clustering analysis has a growing role in the study of co-expressed genes for gene discovery. Conventional binary and fuzzy clustering do not embrace the biological reality that some genes may be irrelevant for a problem and not be assigned to a cluster, while other genes may participate in several biological functions and should simultaneously belong to multiple clusters. In addition, most algorithms cannot generate tight clusters that focus on their cores or wide clusters that overlap and contain all possibly relevant genes. The primary aim is to develop a clustering paradigm with better performance specifically for biological studies with a view to gene discovery.
This project will involve programming, signal processing, machine learning, mathematical analysis, and good writing ability for presentation of technical work. An ideal candidate will have a very good Master degree or a First Class Bachelor degree.

Funding Notes

Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: View Website. Recently the UK Government made available the Doctoral Student Loans of up to £25,000 for UK and EU students and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.)
