SPEAKER:
Dr. Zhongwang Dou, Assistant Professor
Mechanical Engineering, Northern Arizona University

TOPIC:
Towards understanding of biomedical and biological system using particle image velocimetry technique

ABSTRACT:
Engineering approaches are ubiquitous yet emergent when dealing with critical questions related to human health. Particle image velocimetry (PIV) is a novel machine vision technique for non-invasively diagnosing particulate flows. The motion in both particle phase and fluid phase can be spatially and temporally resolved. In this talk, I will discuss how to employ the PIV technique to measure the flow field in biomedical and biological systems, with emphases on both fundamental discovery and engineering applications.
Specifically, I will present three examples, namely (1) flow dynamics in auto-injection drug delivery devices, where fluid shear/strain rate are being compared at different sloshing sensorial; (2) hemodynamics in cerebral aneurysm, where strategies of validation and verification between experiment and simulation are discussed; and (3) swarm dynamics in mosquitos, where the acoustic effect on mosquito flight dynamics are quantified.

BIO:
Dr. Zhongwang Dou is an Assistant Professor at Northern Arizona University. He was a postdoctoral research associate at the School of Mechanical Engineering at Purdue University. In this role, Dr. Dou works on advancing the fundamental understanding of fluid dynamics in drug-delivery medical devices through the development and employment of novel flow measurement techniques. Before joining Purdue, Dr. Dou worked as a postdoctoral fellow at the Department of Mechanical Engineering at Johns Hopkins University, where he
utilized particle image velocimetry to discover the potential feasibility of using acoustics to prevent mosquito-borne disease. Dr. Dou also worked as a research scientist at the Canon Strokes & Vascular Research Center,
focusing on experimental validation of hemodynamics in the cerebral aneurysm. Dr. Dou received his Ph.D. degree in Mechanical Engineering from University at Buffalo in 2017, and B.Eng in Thermal Science and Energy Engineering from University of Science and Technology of China in 2012. Dr. Dou has authored more than a dozen archival publications in journals and conferences such as Journal of Fluid Mechanics, Journal of Biomechanical Engineering, Current Medical Research and Opinion, Scientific Reports, and Experiments in
Fluids.
