Profile Summary

I am an expert in microfluidics and its application to microbiology, biotechnology, and analytical chemistry. For my PhD, I designed, constructed, and tested microfluidic devices meant to be used in medical diagnostics. The projects that I led and finalized include: a device for highly precise dilution of samples in microliter droplets; a device for passive emulsification of multiple samples with a physical characterization of the device; a device for analysis of minimum inhibitory concentration of an antibiotic for single cells; a device for study of active Janus particles at the oil/water interface. Currently, I am working on physics of biofilms and antibiotic resistance of biofilms. I am the leading author of 5 peer-reviewed scientific publications, and a co-author of another 3. I am a co-author of 2 patent applications. I have successfully applied for research grants: by myself for the Etiuda grant (ca. 25 000 USD) from the Polish National Science Centre or the Bekker grant (ca. 100 000 USD) from the Polish National Agency for Academic Exchange; as a collaborator for Maestro grant (ca. 1 200 000 USD) from the Polsih National Science Centre or for the Team-Net grant (ca. 1 200 000 USD) from the Foundation for Polish Science. I have gained my experience at multiple academic institutions such as Broad Institute of MIT and Harvard, University of Cambridge, Ecole Polytechnique Federale de Lausanne, Dresden University of Technology, Delft University of Technology, Wageningen University.
