Lukas Untersteiner

Lukas Untersteiner earned a B.S. degree in Psychoacoustics from the University of Washington and continued to advance his technical education in audio engineering while attending SAE Institute in San Francisco. Lukas has spent many years using his background in acoustics and his talents as a musician playing in bands, engineering recordings, and supervising audio for corporate media projects. But it was his passion for science and technology that also led Lukas into the field of education.

During the past several years Lukas  has divided his time between his music interests and teaching math and science.  He has worked at several tutoring centers around the Seattle area, helping middle and high school students excel in their STEM classes and prepare themselves for standardized tests. 

Lukas describes his pedagogical style as easygoing and conversational, and, as such, is a proven and popular addition to the ME faculty: “I try to keep the student talking as much as possible to keep them engaged. I get my students to analyze their own thinking in order to optimize their problem-solving skills.” Students immediately find his classes engaging and their teacher easy to relate to. Lukas pursues teaching with a passion and commitment because he believes “being a small part of a young person’s intellectual development is very meaningful, and I am grateful for the opportunity.” 

When Lukas is not teaching or working on music projects, you can find him working on his car, playing tennis, or bird watching.
