Dr Allam also holds a Courtesy Faculty appointment at Cornell University’s College of Veterinary Medicine

Main research interests:

  • Pathology and immunology of marine invertebrates
  • Early interactions at water-tissue interfaces between suspension feeding bivalves and waterborne microbes (tissue colonization by microbes, particle sorting in suspension-feeders)
  • Marine genomics
