Daniel Coumbe has held research positions at Syracuse University in New York, Jagiellonian University in Poland, and the prestigious Niels Bohr Institute in Denmark. Daniel has published 14 peer-reviewed research papers on theoretical physics, including articles in world-leading journals such as Physical Review Letters and Classical and Quantum Gravity. Dr. Coumbe is the author of a graduate-level textbook on quantum gravity, Magnifying Spacetime: How Physics Changes with Scale. He has taught college-level courses in physics and mathematics and has given numerous presentations at international physics conferences.
Daniel was born in England but currently lives in Denmark with his wife and two children.
