Scientific Expertise

“Wonderful as are the laws and phenomena of electricity when made evident to us in inorganic or dead matter, their interest can bear scarcely any comparison with that which attaches to the same force when connected with the nervous system an with life (…)”
Michael Faraday 1838


Scientific expertise(*): Ivan Fernando Gonzalez got a BS in Physics from Universidad de Los Andes (Colombia) working on both experimental High Energy Physics and theoretical Biophysics. He volunteered for four years at the Atmospheric-Muons Telescope, and pioneered in the Biophysics group with his dissertation on a Computational Model of Electroreceptor Cells.

After graduation, he started doing electrophysiology with Carlos Sevcik during a short stay in Venezuela, measuring the effects of toxins from scorpion and venomous fish on the electric function of nerves and muscles.

Later he moved to California to become an expert on the electric sense of sharks and rays with Adrianus J. Kalmijn, and got his PhD in Oceanography from Scripps Institution of Oceanography at UCSD. As a graduate student in oceanography–while training sharks and studying the ampullae of Lorenzini– he also had the chance to learn about our changing ocean and our warming planet.

As a postdoc with Sharona Gordon at University of Washington- Seattle, he learned how to measure the electric currents of neurons and cultured cells, while simultaneously recording movies of fluorescent molecules inside the cell. He spent three years at Gordon’s lab doing basic-research experiments that wanted to unveil the early stages of chronic pain by using pharmacology, electrophysiology, imaging, and optogenetics.
