I am currently working as a Machine Learning Engineer at Lirio, a behavior change company. I am particularly interested in using deep learning (DL) and reinforcement learning (RL) methods to determine the best next action (BNA) and select contents to provide personal composed messages (PCM) to our target recipients. I am also interested in other machine learning areas, such as ranking algorithms, information retrieval, recommender systems, etc. Recently, I am stepping my foot into research areas such as natual language processing (NLP), word embedding and semantic analysis.


Prior to Lirio, I was a thesis-track M.S. student in Dept. of Computer & Information Science, Indiana University-Purdue University at Indianapolis (IUPUI). My advisor was Dr. Xia Ning, who has advised my thesis in Machine Learning Methods for Better Drug Prioritization.


I have received my B.S. in Business with High Distinction from Kelley School of Business, Indiana University May 2015, and from Sun Yat-sen Business School, Sun Yat-sen (Zhongshan) University in June 2015.


I am conscientious and responsible in both individual and team work. I also possess strong interpersonal skills, excellent customer service skills, as well as strong attention to details. I am proficient in project management, market research, team development and collaboration.
