Upcoming Presentations

#

Sean D. Peterson is an Associate Professor in the Mechanical and Mechatronics Engineering department at UW. He joined the engineering faculty in June 2009 after spending two and a half years as a Visiting Assistant Professor in the Mechanical and Aerospace Engineering department at the Polytechnic Institute of New York University, where he retains an Affiliated Faculty position. He grew up in San Diego, California, and received his graduate degrees from Purdue University.




Postdoctoral Researchers

#

Paul Hadwin, Ph.D.

Paul is working on inferring human vocal fold tissue parameters from clinical measurements, including vocal fold kinematics and glottal flow rate, using Bayesian analysis. Paul is an applied mathematician and is working on employing Bayes' theorem to the mechanics of speech.


#

Peng Zhang, Ph.D.

Peng is developing multi-functional seed particles for particle image velocimetry (PIV). The seed particles are hydrogel based and enable environmental sensing, with the primary focus on measuring pressure. When used in conjunction with standard PIV, these novel particles will allow simultaneous measurement of pressure and velocity within a fluid domain. Peng is co-supervised by Dr. Maurizio Porfiri at NYU:Poly.


Ph.D Students

#

Jon Deng
Degree expected August 2022

Jon is involved in a multi-institutional grant from the National Institute of Health in the US to elucidate the underlying mechanisms contributing to vocal hyperfunction. Jon is focused on translating clinical measures of individuals into simplified numerical models, with the ultimate aim of providing clinically useful output data that would be otherwise difficult or impossible to measure clinically.


#

Jia Cheng (Winston) Hu
Degree expected December 2019

Winston is examining the impact mechanics of a vortex ring impacting an annular disk for energy harvesting applications. Previous work in this area has involved cantilevered beams. Winston is performing a set of experiments examining the energy harvesting capabilities of ionic polymer metal composite annuli impacted by vortex ring trains.


#

Cederick Landry
Degree expected August 2021

Cederick is part of the research team exploring advanced compression technologies for improving lower limb circulation during a variety of activities, ranging for rest to heavy exertion. Specifically, Cederick is exploring alternative actuation modalities to generate compression to the leg within a small time window of the cardiac cycle. Cederick is also exploring optimization of the compression timing and protocol using machine learning.


#

Supun Pieris
Degree expected August 2022

Supun is examining the coupled fluid-structure interaction of a fence in a boundary layer flow. Of interest is the vibrational characteristics of a fence due to various naturally-arising frequencies in the flow, including from the upstream separation shear layer, shear layer vortices originating from the top of the fence, and low frequency pulsation of the large downstream separation bubble. Supun is co-advised by Dr. Serhiy Yarusevych.


#

Alireza Pirnia
Degree expected May 2019

Alireza is investigating the dynamics of a flexible beam subject to the pressure field induced by a passing train of vortices. This theoretical and experimental work has two primary motivations: (i) to elucidate the influence of intra-glottal vortices on the dynamics of the vocal folds; and (ii) energy harvesting from the fluid when the beam is replaced by a smart material. Alireza is co-advised by Dr. Byron Erath at Clarkson University.


#

Caddie Zhang
Degree expected April 2020

Caddie is part of the research team investigating droplet dynamics on a solid surface subjected to an air jet. Caddie is primarily responsible for conducting the experimental campaign exploring the imposed aerodynmaic loading and the resulting influence on droplet shape and motility. Caddie will be using measured aerodynamic loads (both direct and indirect) to develop semi-empirical models of droplet dynamics. Caddie is co-advised by Dr. Serhiy Yarusevych.


Master's Students

#

Allie Fawcett
MASc Degree expected August 2018

Allie is working on an advanced active compression system to aid in the return of blood from the lower limbs. Specifically, she is focused on developing the sensor platform and feedback controller to ensure that compression occurs at the optimal time and at the proper levels.



#

Ben Pocock
Degree expected August 2018

Ben is studying the one-dimensional dynamics of a cylinder spring-mounted in a cross flow. Ben is using a novel cyber-physical system, wherein fluid loading is measured experimentally and fed into a reduced-order model of the dynamics to determine the appropriate displacement. The cylinder is then actuated in real time in response to the load. This enables parametric evaluation of governing parameters by changing the spring (and mass ratio) in software.


#

Alex Stothart
Degree expected August 2020

Alex's research is at the interface of engineering and sport. Alex is working with STAC Performance on refinement of their Virtual Wind Tunnel technology. His initial focus is to explore the impact of dynamic rider motion through their pedal stroke on total cyclist drag, which will serve as the basis for a study on rider position optimization.
