Aqueous solutions of oppositely charged polyelectrolytes undergo liquid-liquid associative phase separation into a highly dilute supernatant and a polymer-rich condensed phase called complex coacervate. Artem uses statistical physics approaches to explore various aspects of this phenomenon, such as liquid crystalline ordering in coacervate containing semiflexible polyelectrolytes and the effect of the sequence of charges in polyions on the coacervate properties. His research is also devoted to the development of a theory of complex coacervate core micelles. To a large extent, his theoretical work is done in the context of the collaboration including experimental activity and computer simulations.


Artem was born and raised in Voronezh, Russia. He received his master’s degrees in physics with Honors from Lomonosov Moscow State University in 2013. During his PhD, Artem studied swelling behavior of polyelectrolyte networks under the guidance of Prof. Elena Kramarenko at Lomonosov University, and simultaneously developed a theory of non-uniform and non-isotropic swelling of polymer microgels under the co-advisement of Prof. Igor Potemkin and Prof. Martin Möller in DWI - Leibnitz Institute for Interactive Materials at RWTH Aachen University, Germany. He moved to Pau, France in 2017, where worked as a postdoctoral researcher in the group of Dr. Oleg Borisov in cooperation with Dr. Ekaterina Zhulina.

Artem joined the de Pablo group in November 2018 and is currently a postdoctoral fellow at the Pritzker School of Molecular Engineering working as a theorist on coacervation-related phenomena. In his spare time, he enjoys watching/playing chess and watching ice hockey.
