Faculty

Cambridge instructors are master teachers, of whom four have doctoral degrees, one is a Ph.D. candidates, and six others have master’s degrees in their areas of teaching. Faculty members are scholars who are willing and committed to bringing their interest and expertise to the classroom and facilitating curiosity in their students. Small class size truly enables these master teachers to be highly engaged with students personally and academically, which is critical to the school’s culture of encouraging independent thought and challenging discussion.

B.S., Exercise Physiology – Texas A&M University

Professor Martin teaches Spanish and has been with Cambridge since 2017. Born in LaSalle, Illinois and raised in Dallas, Texas, Professor Martin had the privilege of studying Exercise Physiology at Texas A&M University. She was able to utilize her degree in the hospital and health club setting. Soon after, Professor Martin had a passion for travel and decided to pursue a position in the airline industry. She worked in Washington D.C., Chicago, Illinois and Dallas, Texas with American Airlines. Through her work, mission trips (Mexico, Bolivia, Honduras, Guatemala), and personal travel experiences, she discovered a love for the Spanish language and culture. She spent some time studying the language in Spain and Costa Rica and as a result, felt the Lord calling her into education, which led her to obtain a master’s degree in Instructional Leadership at the University of Illinois at Chicago. After thirteen years of teaching Spanish and bilingual education at the primary and secondary levels in the public school system, she decided to return to higher education to pursue another master’s degree in Spanish Literature at the University of North Texas with a desire to teach at the college level. However, the Lord had different plans and those plans joyfully led her to The Cambridge School of Dallas. Professor Martin enjoys serving her students and observing them evolve into mature young adults who have a passion for Christ and learning. When she is not sharing her love for the language, she enjoys outdoor activities and traveling (especially to Spanish speaking countries) with her husband, Tom, reading, and spending time with family and friends.

Mathematics

M.A., Christian Education – Dallas Theological Seminary
M.S., Audio Acoustics – University of Salford (England)
B.S., Electrical Engineering – University of Florida

Prof. Nine teaches upper school math and physics and has been with Cambridge since 2015. During undergrad years, her coursework specialized in the mathematics of signal processing, and for her honors thesis project she used C++ to program a microprocessor which optimized the attenuation performance of a loudspeaker limiter circuit. For her master’s level thesis project, she tried to reproduce an acoustical “iridescence” effect, an analogue to traditional visual iridescence. To do this, she used COMSOL Multiphysics software with a Matlab interface to design and calculate the wavenumber and characteristic impedance of a given acoustic metamaterial at varying incidence angles. During her summers between courses, she worked in numerous engineering internships with organizations ranging from NASA to General Electric. Before coming to Cambridge, Prof. Nine spent a few years as an engineer in Boston, MA for COMSOL Multiphysics. There she taught courses and explained to fellow engineers how to best use the finite element modeling (FEM) software to simulate the applicable physics couplings related to their own custom design prototypes. Upon moving to the Dallas area and while working on her seminary courses, she taught Physics and New Testament classes for one year at Heritage Christian Academy in Rockwall, TX. Prof. Nine also has a minor in cello performance and has studied and performed abroad in Salzburg, Austria. She is a member of The Village Church (Flower Mound), and in her free time she likes playing video games, taking long walks, and spending quality time with her husband and two young children, Annelise and Levi.
