AI for Financial Services
As an accomplished data scientist with strong engineering foundation, I am passionate about leveraging AI to drive business efficiency and solve complex enterprise problems. With over 7 years of industry experience, I have developed scalable AI products and solutions across finance, e-commerce, and technology sectors. I excel in leveraging machine learning (ML), natural language processing (NLP), and generative AI (GenAI) to drive digital transformation and optimize business processes. At EFG International, I have implemented LLM solutions for internal knowledge search (RAG system) and AI agents for credit memo generation, significantly enhancing productivity for business users. Additionally, I am skilled in fine-tuning LLMs and applying graph analytics to uncover hidden insights and detect anomalies in financial data. I am particularly well-versed in integrating AI into enterprise operations, collaborating with cross-functional teams, and fostering AI adoption through training and mentorship. I earned my Ph.D. in Information Systems in 2017 and have extensive publications and patents in AI and data science. Beyond work, I’m a curious traveler who always enjoys engaging with diverse perspectives and exploring new experiences.

Text to Knowledge Graphs with LLMs
August 1, 2025 – September 1, 2025
This is an application that extracts knowledge graphs from natural language text. It's a Gradio web app that uses either OpenAI GPT-4.1-mini via Azure or Phi-3-mini-128k-instruct-graph via Hugging Face to extract entities and relationships from text, then visualizes them as interactive graphs.
Real-time Dwell Time Prediction Using Passive Wi-Fi Data
May 1, 2016 – July 1, 2016
The vast penetration of wireless devices today gives rise to a secondary functionality as a means of tracking and localization. In order to connect to Wi-Fi networks, mobile devices have to scan and broadcast probe requests on all available channels, which can be captured and analyzed in a non-intrusive manner. Thus, one of the key applications of this feature is the ability to track and analyze human behaviors in real-time directly from the patterns observed from their Wi-Fi-enabled devices. This project aims develop such a system to obtain these Wi-Fi signatures in a completely passive manner coupled with adaptive machine learning techniques to predict in real-time the expected dwell-time of the device owners.
Self-driving Using Reinforcement Learning
December 1, 2015 – April 1, 2016
Reinforcement learning is at the heart of modern AI techniques. In this project, I apply the main ideas of reinforcement learning called Q-learning to an interesting hypothetical application called Smartcab. Smartcab is a simplistic simulation of a self-driving car that ferries people from one arbitrary location to another. This application demonstrates how Q-learning can be used to train smartcabs to desired self-driving behaviors through trials and errors. The application is developed using Python and the Pygame framework.
Fine-grained Traffic Speed Prediction Using Big Data
June 1, 2015 – April 1, 2016
• Collected large-scale and fine-grained traffic speed readings from sensor networks in two U.S. cities: Pittsburgh and Washington, D.C. • Proposed efficient local Gaussian processes based on matrix factorization for real-time and fine-grained inferences of traffic flow throughout the road networks.
Image Classification
August 1, 2014 – December 1, 2014
We perform image classification on the CIFAR-10 dataset, where each image belongs to one of the 10 distinct classes. The images are small, of uniform size and shape, and are RGB colored. We implement an image preprocessing framework to learn and extract the salient features of the training images. With preprocessing, we see a considerable improvement of more than 15% from the baseline. We also experiment with a variety of classifiers on the preprocessed images and find out that a linear SVM performs the best. We finally experiment with ensemble learning by combining a SVM with a multinomial logistic regression, which marginally improves on the linear SVM at a high complexity cost.
Human Mobility Analytics
January 1, 2013 – May 1, 2015
We collected big mobility data of visitors to the resort island of Sentosa, Singapore. The data was collected through bundle packages and associated RFID-enabled devices. We propose various analytical frameworks to model and predict the visitors’ trajectories. Our methods include revealed preference analysis and reinforcement learning. Applications include designing optimal bundle packages and recommending optimal plans to the visitors to avoid congestion.
