• Collaborated with a colleague to enhance online consulting session reservation system, integrating voice and video chat functionalities by using WebSocket and WebRTC technologies, resulting in 60% decrease in reservation confirmation time

Undergraduate Researcher

• Developed a comprehensive benchmark for evaluating visual language models (VLMs) on perception and reasoning quality in QA tasks
• Developed an intuitive annotation tool that improved the annotator experience, enabling efficient curation of over 1,600 fine-grained annotated samples
• Tested on over 25 VLMs to assess self-critique and correction abilities
• Introduced a novel evaluation metric, namely VISCore, which incorporated answer accuracy, step-wise critique accuracy, and critique quality
• Improved critique accuracy by 8% through agent-based critique generation

Research Intern

• Refined a graph theory solution to minimize tests and time used in identifying infection within a community network using Python
• Developed data pre-generation script using Python, resulting in a 70% reduction in test time for a population size of 20k
• Improved testing script with Jupyter and JSON that enabled test creation and logging with 20% overhead reduction
• Originated a community-aware diagonal splitting algorithm using a divide-and-conquer strategy which factored in community structure; the new algorithm needed 10% less tests compared to 5 other commonly-used algorithms
