Advances in fluorescence microscopy, such as the ability to perform high resolution imaging of specific structures in live cells over days, combined with automated methods for image analysis, have provided great insight into common human diseases. These powerful techniques provide a 3-dimensional view of biological specimens, as they change in time during development and in the course of disease.
Our mission is to work closely with researchers at the Institute to give them access to state-of-the-art microscopy and expert advice on how to advance their discoveries using imaging methods.

The imaging lab is working collaboratively with research teams to apply methods that have emerged in recent years, which improve both 3D and 4D image capture and the reconstruction of large-scale tissue areas or whole mount specimens from serial sections.

Quantitative analysis of Plasmodium ookinete motion in three dimensions suggests a critical role for cell shape in the biomechanics of malaria parasite gliding motility.

This project aims to increase sample throughput and minimise manual operations by applying new software tools that increase automation. These methods promise to overcome some of the major challenges in microscopy, such as the capture of live specimens with high spatio-temporal resolution.

The application of quantitative methods for the segmentation and extraction of features in digital images is critical for understanding the statistical importance of observations made in biological imaging. We work with a number of software packages to improve the automation of image segmentation and the export of measured parameters. Where possible, we streamline data analysis using open source and free software, to give researchers greater independence and to encourage wider collaboration. We are also working on ways to manage and process large data sets (up to 100s of gigabytes in size) to ensure we can avoid bottlenecks commonly associated with new technologies, which have continually increasing rates of data output.
