Specific Interests

I am interested in the role of metals in biology and toxicology. Essential metals like iron, zinc and copper are required by all organisms to thrive. However, the same properties that make these metals necessary for life also make them extremely toxic. Therefore, organisms have evolved systems to handle metals thus avoiding dangerous and wasteful nonspecific interactions. Several proteins are involved in the tight regulation of intracellular metal concentration and distribution that is defined as metal homeostasis. The study of this sophisticated machinery at the molecular level will ultimately help us understand how organisms acclimate and adapt to multiple environmental stressors including metals. This research uses fish and in vitro models of epithelial barriers (i.e. fish gill and gut). Methods applied span from analytical chemistry to molecular biology and cellular imaging.
