Dr. Martin has held industrial positions in a wide variety of fields. His early work was in medical physics and biotechnology – developing radiation treatment planning software, modeling the cells of organisms as networks of their biochemical pathways, developing microarray technology for genomics, and developing techniques for predicting the structure of proteins based on their primary sequences of amino acids. Later, he worked in materials science, investigating the properties of an innovative lattice material, intended for use over an extensive range of scales. This work involved creating a detailed mathematical model and large-scale computer simulation of the material. Most recently, he was the senior digital signal processing engineer at Audio Precision, where he developed algorithms and software for use in extremely sensitive and accurate audio test and measurement equipment. Algorithm and software development has always been a strong and consistent theme in his work and he has developed professional-quality software in many languages on a large number of computing platforms.
Throughout his career, Dr. Martin has sustained a passion for teaching and mentoring. He taught courses at the University of Arizona, the University of Colorado, Washington State University, and in previous positions here at Portland State. He has always mentored junior colleagues, assisted with courses as an undergraduate and in graduate school, and sponsored Capstone projects in the department in his position at Audio Precision. His current focus is helping students develop the knowledge and skills they will need to be successful engineers, improving his own teaching techniques, and helping the Department and University improve instruction in whatever small ways he is able to contribute.
He is a member of the Audio Engineering Society (AES) and the Society for Industrial and Applied Mathematics (SIAM) and a past member of the Biophysical Society and the American Geophysical Union (AGU). He has also served as the Vice President of Programming for the Rose City Astronomers (RCA), which is a roughly 1600-person nonprofit educational organization with close ties to the Oregon Museum of Science and Industry (OMSI), since 2011.
