Dimitri Deheyn is in the Marine Biology Research Division at Scripps Institution of Oceanography, University of California, San Diego.

Deheyn is a marine biologist who has been studying ecotoxicology for more than six years.

Originally from Belgium, he received B.S., M.S., and Ph.D. degrees at the Free University of Brussels where he first became involved in research on marine organisms producing bioluminescence.

After remaining there as a postdoctoral scientist studying impact of dredging on marine organisms, he then moved to Scripps Institution of Oceanography.

Since, his research theme is to develop a bioassay using bioluminescence of marine organism to assess toxicity of metal polluted sediment.

Deheyn is the principal investigator of SIOSED, the Scripps Institution of Oceanography SEDiment research group, an international project funded by the Venice Water Authority through its concessionary Consorzio Venezia Nuova.
