I am currently a data scientist at Agoda. Before that, I was a machine learning developer at SAP Asia in Singapore from July 2017 to July 2019. At SAP, I was a member of the ML Digital Core team, where we tried to automate the enterprise financial accounting processes using machine learning. In particular, our product is called SAP Cash Application, which aims at automating the complex accounts receivable processes.
From January 2013 to May 2017, I was a Ph.D. student in Information Systems at the Singapore Management University (SMU) under the supervision of Prof. Hoong Chuin Lau. My Ph.D. dissertation focuses on a general machine learning framework to solve a diverse set of problems in urban environments, such as law enforcement and urban transportation. I am generally interested in applying machine learning and spatiotemporal data analytics to solving problems in urban computing. Check out my complete list of projects.
During academic year 2014–15, I was an exchange Ph.D. student at Heinz College, Carnegie Mellon University (CMU) in Pittsburgh under the supervision of Dean Ramayya Krishnan and Prof. Siyuan Liu. In the summer of 2016, I did an internship at IBM Research – Singapore, where I worked on a project that predicts people’s dwell time (a.k.a. “length of stay”) non-intrusively in retail environments using real-time Wi-Fi data. Check out my full lists of publications at DBLP and Google Scholars.
Prior to that, I had obtained my bachelor’s and master’s degree from the Nanyang Technological University (NTU) in 2009 and 2012, respectively. I did a winter internship in 2009 at the Hochschule für Technik Rapperswil (HSR) in Switzerland as a software engineer, where I worked on a refactoring plug-in for Eclipse CDT. During 2010-12, I worked for the university as a research staff under Ning Chen. In the summer of 2012, I interned at Wunderman, Singapore as a data analyst.
