Faculty + Staff

Matthew
Johnston
Associate Department Chair and Associate Professor

Johnston received his Bachelor or Arts and Master of Science in Mathematics from the University of Guelph (2006) and his Ph.D. in Applied Mathematics from the University of Waterloo (2011). Before joining the faculty at LTU, he was a Van Vleck Visiting Assistant Professor at the University of Wisconsin-Madison (2012-15) and a tenure-track assistant professor at San Jose State University (2015-19).

His current research focuses on model analysis of biochemical reaction networks such as signal processing pathways and gene regulatory networks. These models have provided significant insight recently into the biochemical mechanisms underlying circadian rhythms, the cell cycle, and homeostasis, and have also contributed to understanding diseases such as cancer and diabetes.

A recurring feature in this research is clarifying the connection between the topology of the network of interactions and the corresponding dynamical behaviors, using both the deterministic (ODE) and stochastic (CTMC) modeling frameworks.

Use Your Cell Phone as a Document Camera in Zoom

  • What you will need to have and do
  • Download the mobile Zoom app (either App Store or Google Play)
  • Have your phone plugged in
  • Set up video stand phone holder

From Computer

Log in and start your Zoom session with participants

From Phone

  • Start the Zoom session on your phone app (suggest setting your phone to “Do not disturb” since your phone screen will be seen in Zoom)
  • Type in the Meeting ID and Join
  • Do not use phone audio option to avoid feedback
  • Select “share content” and “screen” to share your cell phone’s screen in your Zoom session
  • Select “start broadcast” from Zoom app. The home screen of your cell phone is now being shared with your participants.

To use your cell phone as a makeshift document camera

  • Open (swipe to switch apps) and select the camera app on your phone
  • Start in photo mode and aim the camera at whatever materials you would like to share
  • This is where you will have to position what you want to share to get the best view – but you will see ‘how you are doing’ in the main Zoom session.
