Dr. Özer's research projects use mathematics, engineering, material science, control theory, optimization, and computer simulations to better understand controlled physical phenomena ranging from purely elastic to smart material systems. The problems my research group approaches have applications such as MEMs, space robotics, energy harvesters, and other structurally-embedded smart material systems being used in industry.

Calculus is not hard yet fun if it is taught right. Calculus can be enriched for active and problem oriented-teaching and for fostering mathematical experiments and discoveries both in classroom and at home. Illustrations with interactive and real-world demonstrations help students better comprehend calculus concepts. This way students better appreciate Calculus. I have been developing my own Wolfram’s Demonstration Projects, in addition to the (recently popularized) Desmos and Geogebra simulations. With its rules, formulas and derivations, calculus and differential equations can be overwhelming for some students. Without simulations it is so dry. Someone should show them the good side of calculus with visuals and make it more fun. I have produced over 850 short instructional videos for calculus and differential equations. Some of them are free-access and have been watched over 750,000 times at my YouTube Channel: http://www.youtube.com/c/mathbydrozz

Cengage, a textbook publisher, has recently acquired the rights of around 100 videos I recorded only for them. These videos are blended in their e-book, A First Course in Differential Equations with Modeling Applications by D. Zill, via the platform called WebAssign, a student assessment system, and accessed by approximately 165 countries and territories around the world.
