Chrisna Nguon, currently a master’s student, has completed his first year of the NSF GK-12 fellowship.  Under the fellowship, Chrisna has been working with Gardner High School bringing resources and experience from the university setting to the high school classroom.  Specifically, he is involved in physics and environmental science classes, teaching students computing concepts with the R programming language.  The concepts the students learn are then applied to data visualization and analysis during lab experiments in class.  Chrisna has also presented and developed short lessons on his research to the high school students.  His research topic involves the computation of the acoustic scattering at the difference-frequency generated from the nonlinear interaction of two high-frequency beams.
