Professor Fichthorn’s research is primarily in multi-scale materials simulation, in which she develops and applies theoretical techniques ranging from quantum density functional theory to molecular dynamics, Monte Carlo methods, and continuum theories to a diverse array of fundamental problems involving fluid-solid interfaces. Applications lie in nanoscale materials, thin-film and crystal growth, colloidal assembly, and wetting. In addition to being recognized by Penn State for her outstanding research and teaching, she is the recipient of the NSF Presidential Young Investigator Award (1990), an Alexander von Humboldt Research Fellowship (1998), she is a Fellow of the American Physical Society (2011), a Fellow of the American Institute of Chemical Engineers (2017), a recipient of the Nanoscale Science and Engineering Forum Award of the American Institute of Chemical Engineers (2019), and a recipient of the Langmuir Lectureship of the American Chemical Society (2020).
