Ellis S.
Dr. Ellis S. brings a unique combination of advanced mathematical training, engineering expertise, university teaching, and more than 25 years of experience teaching and tutoring mathematics.
Ellis began his professional career as an engineer and ultimately served as a Senior Principal Engineer at Raytheon Systems Company, where he specialized in the design and analysis of airborne radar systems. During his engineering career, he also developed and conducted technical training programs for engineers at Raytheon, various University Extension courses, and at Air Force and Navy bases throughout the continental United States, including training for a group from the Israeli Air Force. He holds a PhD in Engineering from UCLA.
Following his retirement from engineering, Ellis pursued his longstanding passion for mathematics education. He earned an MS in Applied Mathematics from California State University, Northridge (CSUN), and went on to teach and tutor mathematics extensively. His teaching experience encompasses mathematics through Calculus, Differential Equations, Linear Algebra, and Statistics. His most recent university teaching position was at California State University, Northridge.
Ellis particularly enjoys helping students who initially find mathematics challenging. His engineering and teaching backgrounds have taught him to approach difficult mathematical ideas from multiple perspectives and to explain them in clear, understandable terms. He emphasizes genuine understanding and problem-solving skills rather than simply memorizing formulas and procedures.
Now retired from full-time teaching, Ellis finds tutoring especially rewarding. He takes great satisfaction in seeing students gain confidence, overcome obstacles, and discover that mathematical concepts they once found intimidating can become understandable and manageable.
His combination of extensive mathematical knowledge, real-world engineering experience, university-level teaching, and a genuine passion for helping students makes Ellis a dedicated and an effective Mathematics tutor.
