Education

PhD in Physics · University of Copenhagen · 2014

Built atomic clocks beyond the quantum limit and foundational components for quantum computing networks. Physics teaches you to work with ambiguity — designing experiments, interpreting contradictory data, building frameworks when none exist.

M.Sc in Physics · University of Copenhagen · 2011

B.Sc in Physics · University of Copenhagen · 2009
