About
We offer consultations and collaborations to help create research workflows including custom building experimental parts, preparing samples, imaging & other light based techniques, and designing bespoke image analysis pipelines.
Overview
Our infrastructure incorporates a range of light-based biotechnology techniques, providing images across volume, time and spatial resolution scales. We have a well equipped lab space and workshop for preparing samples and experimental parts, a number of image and data processing tools, and can offer expertise to help with experimental design, light based measurements and image analysis solutions.
In addition to supporting the work of other researchers, we are also involved with a number of collaborations and projects of our own, and seek to foster interactions with industry partners to bring emerging imaging technologies to the campus.
Current Projects
We are working to adapt existing or developing novel technology including:
- Small molecule and genetically encoded biosensors
- Experimental multiplexing techniques
- Advanced image analysis tools
to quantitatively study intracellular signal transduction and synaptic transmission. We aim at contributing to a better understand how information is processed at subcellular, cellular, and networks scales and how this processing is altered in neurological disorders.
