Colleagues describe them as "In all the years that I have had the opportunity to work with interns and new graduates, very few have stood out as Yannan has. It has definitely been my privilege to oversee her work and see her rapidly scale the learning curve of our industry. I have been fortunate to work with a lot of smart people but very few have brought the complete mix of curiosity, high-energy, persistence and attention to detail as I have seen working with Yannan. During the year that she worked with our team, we repeatedly exposed her to new and open-ended problems, and she was always able to come back with not one but an ensemble of solutions. Without being explicitly prompted to, she always benchmarked her results on multiple methodologies and came with rigorous recommendations. Yannan already came with a strong background in statistics but she was very quick to understand our systems and data and apply the appropriate methods. In particular she worked on a series of projects that required matching documents or information fields to create engineering alerts. These projects are challenging because the consumers do not want to see an over-abundance of alerts nor miss any key signals. Yannan brought a combination of keyword-matching methodologies to the project that has been widely appreciated by the users and is a candidate to replace a legacy system. Yannan has demonstrated exemplary skills in machine learning and programming with a sound understanding of current practices in NLP. I strongly recommend Yannan's work ethic and professional character - she will make an excellent addition to any analytic team."
