Madison, Wisconsin, United States
Polymer scientist working on new methods and materials for additive manufacturing (or 3D printing)
Additive manufacturing of silicone, polydicyclopentadiene, or proteins by Heating at a Patterned Photothermal Interface (HAPPI)
Responsible for industry-sponsored projects - Developed optimum conditions for 3D-printing of high performance polymers at room temperature - Formulated new products and studied mechanical and thermal properties of the products
Worked on developing new water-soluble and anti-fouling block copolymers that exhibit thermoresponsive gelation in water as a new polymeric draw solute for forward osmosis
• Developed a new class of peptidomimetic polymers (block copolypeptoids) • Developed novel water-soluble block copolypeptoids that exhibit thermoresponsive gelation, and have applications as injectable hydrogels for drug delivery • Developed crystallization-driven thermoreponsive organogels from amphiphilic block copolypeptoids, and studied viscoelastic properties of the gels by rheology
• To teach lab safety and experimental techniques, and provide short lectures 1. General chemistry lab (CHEM 1212, Fall 2008 & Spring 2009) • Student evaluations: 4.81/5.0 & 4.81/5.0 2. Organic chemistry lab (CHEM 2364, Spring 2010, Fall 2010 & Spring 2011) • Student evaluations: 4.87/5.0, 4.65/5.0 & 4.82/5.0 • Some positive comments from students “Chang-Uk was always active in supervising experiments and helping students when they are confused. He also helps us link concepts to everyday life and make it easier to understand.” 3. Macromolecular chemistry lab (CHEM 4010, Fall 2009 & Fall 2011) • Responsible for short lectures and class materials of experiments for first-year graduate students and senior undergraduate students.
