Hi, I'm a researcher in molecular biophysics at University of California, San Francisco. Please visit my research page.

About Me

Who is Ignacia Echeverria

I am a postdoctoral researcher at UCSF at Prof. Andrej Šali laboratory. Previously I was a postdoctoral researcher at University of Maryland working with Prof. Garyk Papoian. I obtained a Ph.D. in Molecular Biophysics at Johns Hopkins University and a bachelors degree in Physics at Pontificia Universidad Católica de Chile.

The overall goal of my research is to obtain rigorous mechanistic insight into the structure and dynamics of macromolecular complexes, with special emphasis on how the interaction between proteins, DNA and carbohydrates determine their biologically relevant function.

On my research I use theoretical and computational methods from molecular biophysics, statistical mechanics, stochastic modeling, molecular modeling and scientific and statistical computing to understand how molecules work.
