Gwynn Elfring

Gwynn Elfring is an Associate Professor at the University of British Columbia's Faculty of Applied Science, Department of Mechanical Engineering. Holding a Ph.D. from the University of California, San Diego, and postdoctoral experience at the University of California, Santa Barbara, Elfring bridges applied mathematics with engineering through asymptotic analysis and numerical methods.

• Education: B.Eng/M.A.Sc. (University of Victoria), Ph.D. (UC San Diego), Postdoc (UC Santa Barbara)

Research Focus: Biological fluid mechanics (cell locomotion, fluid-structure interactions), complex fluids (rheology in shear-thinning systems), capillary phenomena (surfactant-stabilized emulsions), and active matter (density gradient responses). Key themes include viscoelastic effects, microscale dynamics, and non-Newtonian fluid behavior.

Publications span 2017–2024, with recent work analyzing swimming efficiency in viscosity gradients (2024), active particle motion in density gradients (2024), and rheological responses in micellar gels (2021). Collaborations include J.F. Brady (Caltech) and C. Datt (now at MIT).

• Awards: UBC Killam Accelerator Fellowship (2021), Dean’s Service Award (2017)

Elfring's work combines theoretical modeling with experimental collaborations, emphasizing applications in biomedical engineering and industrial fluid dynamics.
