Annie Y.Y. Chang is a Scientific Collaborator at Federal Office of Meteorology and Climatology MeteoSwiss. She is proficient in German and English. Colleagues describe her as "Annie was a major contributor to our team's success while she was at Urbantech Consulting. She was quick to learn and improve our standards for water resources calculations, was attentive to instructions and rapidly grasped hydraulic and hydrologic modelling procedures. She was a great listener, brought a problem-solving approach to challenging issues, and demonstrated strong management capabilities. The two of us ran an extremely busy water resources group for several months and executed many functional servicing and detailed subdivision / water resources design studies in that time. Above all, Annie's personality made her a perfect fit for our team - she is hard working, committed to quality, and is an overall wonderful person." and "I have had the pleasure of working with Annie during her tenure as a Research Assistant on the Energy Matters Summit. Annie successfully implemented and managed two projects by providing valuable insight, keeping detailed records, and assisted with analyzing demographic information. She is a keen learner and hard-working, and it was demonstrated in the projects she completed. I highly recommend Annie because she is driven, detailed-oriented and an effective communicator. She would be an asset to any organization."
