· Fully participated und took charge of the planning, research, analysis and reporting of a supramolecular organogels research project in Max-Planck-Institute. Determined the plan as well as the future direction of the project together with colleagues in terms of the trend in the market, the R & D cycle time, as well as the R & D cost. · This project aims in developing a unique supramolecular organogel with tunable thermal and mechanical properties as well as microscopic structures. This gel possesses a series of great features including the low cost, the easiness of production and the respondence to external stimulation, etc. This gel shows great potential in batteries, pharmaceutical, mechanical engineering, and cosmetics industries. The research results are expected to be published in the summer of 2019. · Participated in the seminar and evaluation of the projects of other research groups in Max-Planck-Institute for several times. Familiar with the complete set of standard R&D process from requirements collection, project design, feasibility analysis, risk assessment to feedback and management.
