Principal Scientific Contributions• Identification of a new Actinomyces species
Buchanan, B.B., and Pine, L. (1962) Characterization of a propionic acid producing actinomycete, Actinomyces propionicus, sp. nov. J. Gen. Microbiol. 28, 305-323.
The organism, originally isolated from a case of lachrymal canaliculitis, was reclassified as Propionibacterium propionicus and later found by others to infect the middle ear and chest.

Current Research Topics and Collaborators
Specific TopicsMy current research focuses on thioredoxin and is carried out collaboratively. We focus on (1) The diversity of thioredoxin and its role in redox regulation in oxygenic photosynthetic prokaryotes and seeds, and (2) Applying thioredoxin to improve the quality and yield of cereals.Thioredoxin (Trx) is a disulfide protein found in all types of living cells. Discovered as an electron donor for ribonucleotide reductase, Trx has since been found to play a regulatory role in a spectrum of processes throughout biology. The protein is also finding a place in medicine and biotechnology.
- Diversity of Trx systems with an emphasis on their role in anaerobic archaea and bacteria and oxygenic photosynthetic prokaryotes.

I have also collaborated with the late Professor Andrew Benson on producing a video on the historic photosynthesis experiments he carried out in Berkeley in the 1940s and 50s with the late Melvin Calvin. Link to Andrew Benson Video.
