Physics. Interested in the galactic environments of living planets – what sorts of galaxies, and what regions in galaxies are likely hosts of life, especially complex life.
Molecular, Cell & Developmental Biology. Studies the origin of the ribosome (and life) from an RNA world and the origin of RNA itself from prebiotic chemistry. He is broadly interested in life as an emergent property of the periodic table.
Biomolecular Engineering. Produces sample nucleic acids in simulations of prebiotic conditions. Studies the role of membranes in the origin of life. David works to understand the assembly of the first living organisms on planet Earth.
