Emeritus Prof. Cindy Greenwood
Hello Everyone, welcome back to another academic year! It’s my great pleasure to announce that we are returning with our weekly meetings for the Math-Bio seminar! As a reminder, these meetings will be happening every Wednesday at 2:00 pm (Pacific Time) in the PIMS lounge (ESB 4133). PIMS tea will follow the seminar at around 3:00 pm.
To kick-start the Math-Bio seminar series of 2025-26 on Wednesday, September 10th, our speaker will be Emeritus Prof. Cindy Greenwood from our math department here at UBC. Below is more information about this exciting talk.
For those unable to attend in person, you can join via Zoom using the link below.
I hope to see you all there!

The rainbow and the brain have in common that frequencies are produced. In both cases there is a function of frequency, f, called the power spectral density (PSD). In both cases invasive investigation spoils the investigated object. This talk will describe using noninvasive electroencephalography (EEG) to evaluate the PSD of the brain, via stochastic modelling of associated brain structure. We explore the popular question: does the human brain manifest the mysterious property called "1/f"? Is the PSD of the brain proportional to the function "f to the power -a", for some a > 0, and hence scale-free? What would that mean about the brain? Independent of these fascinating questions, the exponent, a, has many successful applications as a diagnostic of brain disorders and treatments.
