My general interest lies in the quantitative investigation of cell dynamics and the development of image processing tools for this purpose.
My current research project focuses on leukocyte migration, stimulated by chemoattractants. Recent in vivo studies have shown that these cells alter their speed as they move closer to a source of chemoattractant. Through in vivo imaging in zebrafish and by developing image analysis algorithms, I am studying the driving force behind this leukocyte mobilisation, which is driven by actin dynamics (Video, right). To induce directed leukocyte migration I use assays developed in the Sarris lab such as laser wounding, local bacterial injections or photo-activatable chemokine release.
During my PhD, I developed a software for cell tracking and division for investigation of cell responses to external particle radiation. Analysis of cell fate post-irradiation generates valuable and reliable data for successful charged particle radiation therapy.
