About me

About me

My scientific path began with the research of fundamental issues on the border of materials science and polymer physics. My PhD dealt with the area of crystallization and melting of long polymer molecules under the influence of orienting fields. Then, I went deeper and deeper into the sea of basic problems of phase transitions in polymers. The experimental reality has provided me with more or less clear information on the physical phenomena and those information I tried to face with some models. Sometimes working well, sometimes not. One day I felt that I had accumulated a relatively large amount of fundamental knowledge, and it is high time to move on to more applied research that may be of use to society. Considering the increasing health problems of an aging population on the one hand and the rapidly developing field of tissue engineering as a part of regenerative medicine with extremely high potential and broad perspectives, my natural decision was transferring further activities to the field of tissue engineering defined as an interdisciplinary field that applies the principles of materials science and life sciences towards the development of biological substitutes that restore, maintain or improve biological tissue, function or the entire organ. My idea was supported by the new location of our Institute from 2009, which is now surrounded by other institutes of Polish Academy of Sciences with biological profiles, being natural partners for our cooperation. Additionally, I was inspired to make this shift by my friend and scientific partner, prof. Tomasz A. Kowalewski, who was a pioneer in Poland of  electrospinning as a technique of formation of nanofibrous scaffolds. Bringing my ideas into action I started to build the strong team with interdisciplinary profile as well as to increase of equipment facilities. The change of the activity field forced me to broaden my knowledge, mostly toward biology of cells and the mechanisms of their interactions with materials. It was natural come back to my old fascinations with biology, realizing many years ago during high school education and  during further university education at the Technological University combined with supplementary classes at the Warsaw University of Life Sciences (SGGW). Finally, the dreams came true. Me and my great team are very excited to be able to apply our knowledge to new developments in the field of biodegradable polymers for regenerative medicine with a closer or longer perspective of alleviating human suffering. Finally, I feel that I arrived to the satisfaction and happiness from my professional activity realizing the words of my great spiritual master, Mahatma Gandhi, who said: “Happiness is when what you think, what you say, and what you do are in harmony.”
