Biography

 I received an M.A. in psychology with a minor in philosophy from the University of Helsinki in 2004, writing my master's thesis on the interaction between brightness and color information in the simultaneous contrast illusion. Working with Dr. Pentti Laurinen on my master's thesis made me realize what a powerful tool psychophysics is for studying psychological processes and neural computation. After working in corporate research at the Nokia Research Center for a while, I decided to go back to academia and was offered a PhD studentship with Prof. Karl Gegenfurtner at the University of Giessen. During my time in the lab, I learned color psychophysics and computer rendering, and received my PhD in 2009. To learn more about color and material constancy, I then moved to Philadelphia to work with Prof. David Brainard at UPenn. I learned to calibrate a high-dynamic range display and used it to understand the perception of glossiness and lightness under different natural light fields. While in Philadelphia, I also worked with Prof. Sarah Allred at Rutgers on the relationship between color memory and perception, and finally did a two-year project in Prof. Russell Epstein's lab learning about fMRI adaptation and MVPA methods. I've held an assistant professorship in Durham since September 2015.
