Kamil Krawczyński, PhD

During his Master’s studies, Kamil Krawczyński completed a 6 months Erasmus Program scholarship at the University of Trieste, Italy. After the doctoral studies, he continued his research career as postdoctoral fellow at the Magee-Womens Research Institute, Pittsburgh, USA. Later he returned to Poland and worked at Mossakowski Medical Research Institute PAS in Warsaw. His main research focus is non-coding RNA, including microRNA and using diverse molecular biology techniques he has investigated their role in the epigenetic and post-transcriptional regulation of gene expression.

He is a co-author of 14 scientific papers. During his scientific career he led 1 scientific project, he was also awarded by the Polish Minister of Science and Higher Education Scholarship for outstanding young scientists.

In August 2024, Dr. Krawczyński joined the Computational Genomics Group at ICTER as a research specialist, where he is involved in the realization of the SONATA BIS 12 project aimed at developing methods for multimodal profiling at single cell resolution.

Research groups

We are interested in creating new approaches for comprehensive inference of developmental trajectories and delineation of cell atlases from single-cell data, understanding the role of cell-to-cell signaling and biological pathways in lineage commitment and transitions between cellular states.
