I graduated from the University of Wrocław in the field of medical biotechnology. During my studies, I participated in Socrates/Erasmus program at the University of Reims, France. Afterward, I completed the PhD course at the University of Birmingham in Prof. John Heath’s group. During 2011-2015 I was a postdoctoral fellow at the Cancer Research UK Manchester Institute in Signalling Networks in Cancer group led by Dr John Brognard. In 2015 I received Fuga grant by National Science Centre in Poland that allowed me to continue my research in the Laboratory of Experimental Medicine at the Centre of New Technologies, University of Warsaw. I was also awarded Homing grant by FNP (2017-2019), Sonata grant by NCN (2019-2021) and 3-year fellowship for Outstanding Young Researchers from the Ministry of Science and Higher Education (2016-2019). Currently, I supervise one PhD student and three undergraduate students. I will be taking the position of Group Leader at IMol in 2021.

Piotr received his PhD in 2012 from the University of Cambridge. He pursued his research at the MRC Laboratory of Molecular Biology under the supervision of Jan Löwe. In 2015 he moved for a postdoc in Martin Pilhofer’s group at ETH Zürich. Since May 2019, Piotr has been a junior group leader within the ReMedy International Research Agenda. Throughout his career, Piotr has been interested in investigating membrane-associated molecular machines that are essential in maintaining cellular architecture in health and disease.

Directors of ReMedy International Research Agenda Programme (ReMedy coordinator)


Prof. Agnieszka Chacińska and Prof. Magda Konarska are directors of the programme Regenerative Mechanisms for Health (ReMedy) funded by the Foundation for Polish Science, transferred from the University of Warsaw to the International Institute of Molecular Mechanisms and Machines PAS (February 2021). Profs. Agnieszka Chacińska and Magda Konarska are corresponding members of PAS, members of EMBO and Academia Europea.

ReMedy's activities are focused on research on regenerative mechanisms at the molecular level, including the understanding of the mechanisms of cells' response to disorders caused by environmental, disease or aging factors. This knowledge is expected to help in the development of new therapies and drugs to maintain health and heal, among others, age-related neurodegenerative diseases as well as cancer. Within the ReMedy programme, new group leaders are recruited to form their groups and run independent research enriching the goals of ReMedy. Profs. Chacinska and Konarska serve as mentors to newly recruited group leaders.
