Marco Viero

I am an observational cosmologist and member of the [SPHEREx space telescope](https://spherex.caltech.edu) group at Caltech. Previously I was a Kavli Fellow at Stanford University where I researched the early Universe. I use statistical methods to study intensity fluctuations in the extragalactic background light — a technique known as intensity mapping — to pull out signal from an otherwise noise-dominated background. I did my Ph.D. at the University of Toronto, M.Sc. in physics at the University of Pennsylvania, and B.Sc. in mechanical engineering at Cornell University. I also spent time in the bike industry; at Wahoo Fitness in Atlanta as a data scientist and engineer, and at Parlee Cycles, where I designed carbon fiber race bikes.
