Areas of Interest: Polymeric biomedical materials and drug delivery, with recent emphasis on blood sepsis diagnostics.
Today I am looking for collaboration in mathematical modeling of instabilities in sheared 2-phase flow.
To rapidly identify pathogenic bacteria causing blood infections, we need to quickly separate red
blood cells from plasma.• We have developed a hollow spinning disk (3,000
rpm).
• 7 mL of blood are spun for 1 minute.
• More dense red cells separate to the outer wall and are trapped behind a weir.
• The plasma with bacteria flows over the edge of the weir and is collected and processed.
Basic Hollow Disk Design
• We need to keep the separated plasma from re-mixing with the red cells during
deceleration.
Slow deceleration and retained separation
Fast deceleration and remixing of red cells
High Speed Camera Observations
• A high-speed camera (1 kHz)has been used to take videos ofthe spinning disk to find thevelocity gradient that mixinghappens between the layers ofRBC pack and the Plasma.
Theory for stability• In general:
• For weather systems:
• For 2 phase flow:
• For our system?

Areas of Interest: Systems Engineering and Design, Alternative Energy
Energy Demand
Solar Devices in Public Places• The BYU Engineering and System Design Lab has an
alternative energy research group exploring how to embed solar devices throughout our community and campus
• “Many small and simple devices can make a big difference”o Solar wearables, smartphones, parking lots, bus stops, etc.
• Currently, we’re developing and testing a solar table concept for the BYU library
Where are we going next on CampusBYU bus stops
Solar Posters/Blinds
Sections of walls on BYU buildings that are never
used
Solar benches
Where are we going next in the Community?
Solar “B” and “U”
Solar devices in developing nations
Solar picnic tables at parks
Where else?- Churches- Parking Lots- Shopping carts- Sidewalks- Car shades
- Stadium seats- Camping chairs- Beach umbrellasetc.
How you can help
• Looking for faculty who have a south facing window that would be willing to have a solar device in their window/offices
• Share information with us about departments that have a conference room with large windows
• Inform us of other groups on campus that are exploring similar ideas
• Collaborate with us on future proposals
• Please contact me if interested!
