Cardiovascular Engineering / Urogenital Engineering External Seminar with Ankur Bordoloi.
Natural porous systems, such as soil, membranes, and biological tissues comprise disordered structures characterized by dead-end pores connected to a network of percolating channels. The release and dispersion of particles, solutes, and microorganisms from these structures is key for a broad range of environmental and medical applications including soil remediation, drug delivery and filtration. In this seminar, I will present how we quantify the transport of colloidal particles and bacteria in a structurally heterogeneous porous medium engineered in microfluidic channels. Using experiment, numerical simulation and statistical modeling, I will show how macroscopic transport of such particles is linked to the pore-scale features, emphasizing the effects of dead-end pores.
Dr. Ankur Bordoloi received his PhD (2014) in Aerospace Engineering & Mechanics from the University of Minnesota. He is currently a senior postdoc in the Institute of Earth Sciences at UNIL. Prior to his current position, he conducted postdoctoral research at the University of California, Berkeley and the Los Alamos National Laboratory. Over his academic and research career, Dr. Bordoloi has worked on several problems related to multiphase flows (transport in porous media, droplet dynamics, particle-turbulence interactions, particle-shock wave interactions, plume sedimentation etc.) that have applications in geophysical flows, marine biology, environmental science, biomedical design, and aerospace engineering.
