Nelson Christensen is the the George H. and Marjorie F. Dixon professor of physics.. He has been teaching at Carleton since 1999. He holds He is a graduate of Stanford University and MIT.
His doctoral research used laser interferometric antennas to measure Stochastic gravitational radiation. That led him to join the LIGO Scientific Collaboration searching for the gravity waves Einstein predicted in 1916.
Christensen and several of his students were authors of papers included in the LIGO report which identified gravity waves in 2016.
