I received an M.A. in psychology (minor: 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 to study psychological processes and neural computation. After working in corporate research for a while at the Nokia Research Center, 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 a lot about color constancy (and spray-painting fruit), and received my PhD in 2009 together with a swanky Doktorhut. To learn more about color and material constancy, I then moved to Philadelphia to work with Prof. David Brainard at UPenn. We did some nice experiments with a high-dynamic range display, which was a pain to calibrate but was well worth it. 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.
