I am a chemist and materials scientist specializing in polymers, plastics, and applied research. I am getting my PhD in Chemistry and I got a bachelor’s degree in Materials Science Engineering, with experience spanning synthesis, characterization, and the development of functional materials. I consider myself a problem solver, creative, and experimental. But also I have a passion for teaching general and organic chemistry, supporting student learning, and inspiring curiosity in the next generation of scientists. * Teach Chemistry to all ages and levels * Do research and writing/review proposals * Polymer science consulting (Structure/Properties relationship) *I am open to work in any field, learning, and help during interesting projects
