Faculty Profiles Physics & Astronomy Department Tufts University Arts, Sciences and Engineering   Name: Ken D. Olum Title: Research Assistant Professor Departmental Affiliation: Physics & Astronomy Department Degrees: Ph.D. MIT, 1997 Expertise: General Relativity and Cosmology E-mail: kdo@cosmos.phy.tufts.edu Other websites: http://cosmos.phy.tufts.edu/~kdo/ Scholarship & Research: I work in general relativity in and quantum field theory, particularly on the question of limits on negative energy densities and their effects. I study cosmic strings, ultra-high-energy cosmic rays and cosmological inflation. I also work with anthropic reasoning in cosmology and related philosophical issues. Some recent papers: Conflict between anthropic reasoning and observation, Analysis 64, 1 (2004). http://arxiv.org/abs/gr-qc/0303070 Static negative energies near a domain wall.
