Mosquito larva Malpighian tubules with stellate cells labeled for Na/K ATPase.  M.Patrick

The main goal of my research is to identify and characterize ion transport mechanisms of aquatic organisms, both invertebrate and vertebrate, that inhabit challenging environments. I utilize both gene and protein expression assays to identify candidate transporters and determine how they are regulated under chemically disparate environments.



Current projects:

· Identification and characterization of sodium and chloride excretion in the exceptionally salt-tolerant mosquito larvae (Ochlerotatus taeniorhynchus).

· Identification and characterization of sodium uptake in an acid-tolerant fish, the blackskirt tetra (Gymnocorymbus ternetzi).

· Characterization of the osmoconforming response in the euryhaline mosquito larvae Culex tarsalis

· Characterizing the relationship between sodium uptake and ammonia excretion in freshwater larval mosquitoes (Aedes aegypti).
