Daniel Attinger’s numerical and experimental research is focused on multiphase microfluidics, the dynamical behavior of several fluids or phases constrained by a micro-geometry. Multiphase microfluidic systems typically exhibit multiscale heat and mass transport with transient fluid dynamics, in the presence of multiple deforming interfaces. Current micro and nanomanufacturing techniques provide novel tools to engineer multiphase microfluidic systems, with applications in manufacturing, single cell biology, bloodstain pattern analysis, energy transport and the environment.
Attinger’s laboratory tries to understand, control and enhance these multiphase microfluidic transport phenomena. Typical problems in which we have built expertise are multiphase flow in microgeometries, or the impact with phase change of a single droplet on a solid wall. We have for instance demonstrated that appropriately micro-functionalized interfaces can enhance pool boiling heat transfer, or guide the self-assembly of nanoparticles.
Daniel Attinger is the recipient of the ETH Zurich medal for outstanding Sc.D. thesis (2001). He has produced 25 journal articles, 40 conference papers, 2 book chapters, 2 edited books. He has given five keynote lectures at international heat transfer and microfluidic conferences, and about 30 invited talks in Harvard, Berkeley, MIT, Princeton, RPI, IIT Chennai, ETH Zurich and the Hong Kong University of Science and Technology. Since 2004, the US National Science Foundation, has awarded him five grants as a PI, including the NSF CAREER award for young investigators. Attinger is a member of the American Society of Mechanical Engineers and the American Physical Society.
