Research Interest

Dr. Bridges’ laboratory studies the transport and toxicity of mercury. Her current projects include: the effects of toxic heavy metals on renal function in patients with chronic kidney disease, the effects of mercury-cyanide exposure on zebrafish, and the susceptibility of diabetic patients to heavy metal toxicity.
