Dr. Mary Bossus Jones completed her Ph.D. in December 2012 at the University of Montpellier 2 under the supervision of Dr. Catherine Lorin-Nebel and Pr. Guy Charmantier. Specializing in fish physiology, she used an integrative approach from organisms to molecules in order to study osmosensing and osmoregulation in the European sea bass. She previously earned a Master's degree in marine biology and ecology at the Center of Oceanology of Marseilles and a three-year degree in life sciences (equivalent to a BSc) in physiology and bioengineering at the University of Provence.

After getting her Ph.D., she pursued a first postdoctoral position at the University of Portsmouth on a project entitled "Neuroendocrine disruption in Crustacea," developed by Dr. Alex Ford. It was part of a larger program allowing collaborations between the UK and France. During this time, she was looking into the effects of selective serotonin reuptake inhibitors (SSRIs) on the behavior and gene expression of amphipod crustaceans.

Her second postdoctorate was at the University of Arkansas, where she mainly studied the paracellular pathways and endocrine regulation of osmoregulation in two euryhaline species, the rainbow trout and the Japanese medaka. 

Dr. Bossus Jones started teaching at Lyon College in August 2016.

Currently, her research focuses on the following subjects:

Osmoregulation in aquatic organisms

  • How do fish and invertebrates regulate ions and water movement in freshwater and in sea water?
  • Why are some species able to migrate from freshwater to seawater and vice versa?

Effect of anthropogenic pollutants on aquatic organisms

  •  How do pollutants from human origin affect the physiology and behavior of aquatic organisms?
