Dr. Joanna Kowalska

Assistant Professor

University of Warsaw


Professional background: Joanna Kowalska is an Assistant Professor in the Faculty of Physics at the University of Warsaw (Poland). She completed her Ph.D. studies in Biophysics in 2010 under the supervision of Prof. Edward Darżynkiewicz, at the University of Warsaw. In 2018, she has been nominated to a European Inventor Award. Her research interest focuses on the design and synthesis of mRNA 5’ end (cap) analogues as reagents for preparation of mRNA molecules with application in biotechnology and medicine. She is also passionate about chemical synthesis and studying properties of biologically important nucleotides, oligonucleotides, nucleic acids and their analogues. Her research also covers topics of analysis of nucleotides and nucleic acids by NMR and mass spectrometry, as well as their cellular delivery.
