Tatjana Paunesku from Northwestern University in Chicago visited the team at MedILS and co-organized workshop “Application of Microbeam in Cell Biology“


April 11-14th and April 26th, 2022
MedILS, Split, Croatia
Tatjana Paunesku, Research Associate Professor of Radiation Oncology
Northwestern University Feinberg School of Medicine, Chicago IL, USA 

While radiation is commonly used to induce cellular damage, the usual sources of radiation lack the ability to target individual cells or specific components of a cell. A microbeam is a micrometer or sub-micrometer diameter beam of radiation, that allows damage to be precisely inflicted at specific locations within a biological target. In this way, the effect of radiation on specific cellular functions can be evaluated. Microbeam is particularly useful for studying cell-cell interactions in heterogeneous cellular populations since it can target single cells without reaching the neighboring cells.


Prof. Tatjana Paunesku is a Research Associate Professor at Northwestern University Feinberg School of Medicine, Radiation Oncology Department, in Chicago, USA. Her research interests include radiation biology and nanotechnology, as well as design and construction of novel research devices. These include a custom-made microbeam, as well as Bionanoprobe - a new instrument enabling high-throughput and high-resolution imaging that co-registers both biological material and nanoconstructs.

Workshop program
