Patrick Walsh

Biography

 Patrick Walsh is working as an Adjunct Professor and Director in Department of Biology, at University of Ottawa,canada. His area of Research focuses on how organisms (primarily fish) adapt their physiology, biochemistry and molecular biology to the environment. The emphasis is on nitrogen metabolism and excretion, particularly on the phenomenon of urea excretion by fish (e.g., toadfish and sharks). This program seeks to understand why fish sometimes produce urea (instead of ammonia) from an ecological and evolutionary perspective, and to understand the molecular mechanisms enabling shifts from ammonia to urea production and excretion. Studies of gene expression using Micro arrays will feature more prominently in the future. He is The author of many articles published in several reputed journals.
