Research
Current research interests of Dr. Vladimir Lobaskin lie in the area of theory and simulation of soft matter and nanostructured biosystems. His previous scientific contributions are related to structure and interactions in colloidal dispersions, mechanics of biomolecules, and self-propulsion at the microscale.

Ongoing projects include:

Nano and microfluidics: design of functional interfaces, micro and nanopillar systems, flow control on the micro and nanoscale.

Multiscale modelling of biointerfaces and their protective function: computer simulation study of blood flow, endothelial glycocalix, and cellular membranes and mechanisms of systemic distribution of nanoparticles.

Mechanics of microswimming and active motion: theoretical study of mechanisms of self-propulsion on the microscale, bacterial motility, and cooperative phenomena in ensembles of active objects (swarming, formation of metachronal waves, collective propulsion).

Collaborators:

Max Romenskyy (IRCSET funded PhD student) - active motion and swarming
Mark Ross-Lonergan (summer student) - flow visualisation
