Patrick MATHEWS DELGADO

Studies of the different interactions in the biology, morphology, larval morphogenesis, phylogeny, and coevolution of Sacculina carcini and their crustacean hosts.

Research topics:

• Biodiversity of parasites of aquatic organisms, particularly on fish parasites: Morphological, ultrastructural and molecular phylogenetics analysis.
• Host-parasite interaction: Histological, hematological and ultrastructural analysis.
• Production and development of micro and nano particles for application as drug delivery materials for the treatment of fish parasites using various techniques Isothermal titration calorimetry, small angle X-ray scattering, dynamic light scattering, scanning and transmission electron microscopy and confocal microscopy, histology, hematology, histochemical and immunofluorescence.
