Ren Yi

Ren Yi started working as a research assistant at Brown University in June 2014 and also served as an instructor from September 2014 to December 2017. In this role, they focused on discrete mathematics and utilized computational math fields such as combinatorics and computational geometry to develop geometric representations for studying theoretical discrete dynamical systems. Ren also designed algorithms for constructing self-similar polytope exchange maps and built interactive Java applets for mathematical experiments and pattern visualization.

In June 2018, Ren Yi joined Coalescence Partners as a Quantitative Analyst. In this position, they designed multi-factor stock selection models based on large fundamental stock datasets using statistical and machine learning algorithms for portfolio optimization. Ren improved and maintained existing models and published weekly stock screening reports for decision-making and investment discipline management. Additionally, they conducted back-testings of trading strategies and distributed monthly back-testing reports for equity research until March 2019.

From March 2019 to September 2020, Ren Yi worked as a Senior Data Scientist at Aspen Technology. Their main responsibilities included understanding data patterns and key drivers in chemical processes, preprocessing customer data, and designing and developing machine learning and mathematical models in Python. Ren focused on improving the accuracy and efficiency of chemical engineering processes.

Since September 2020, Ren Yi has been employed as a Senior Algorithm Engineer at Shixing Information Technology (Shanghai) Co., Ltd. No specific end date has been provided for this role.

Ren Yi earned a Bachelor's degree in Mathematics from Stony Brook University between 2009 and 2012. Following that, they pursued their Doctor of Philosophy (Ph.D.) in Mathematics at Brown University from 2012 to 2018.
