About

I am a Master's student in Computer Science at the University of Macau, working under the supervision of Prof. Derek F. Wong at the NLP & Portuguese–Chinese Machine Translation Laboratory (NLP2CT). My research focuses on explainable and trustworthy artificial intelligence for large language models, with particular emphasis on hallucination detection and the evaluation of LLM-generated text. I am also interested in multilingual and low-resource machine translation, including cross-lingual benchmarking and evaluation methodologies. I am fortunate to be closely mentored by Junchao Wu, whose guidance has been instrumental in shaping my research journey.

Research & Teaching Experience

NLP & Portuguese–Chinese Machine Translation Lab (NLP2CT) Mar 2024 – Present

Research Assistant — University of Macau

Macau SAR, China

Implemented and evaluated Transformer-based models (BERT, RoBERTa, GPT-style) for multilingual machine translation; developed test plans, triaged model failures, and iterated on configurations across low-resource language pairs.
Built automated evaluation pipelines (BLEU, ROUGE, WER, BERTScore) into reproducible, containerized workflows using Git and Docker, with experiment tracking via MLflow and Weights & Biases.
Conceived and led IndicDetect, a cross-lingual benchmark for LLM-generated text detection across Hindi, Telugu, and Tamil; drove dataset construction, evaluation framework design, and analysis of zero-shot and fine-tuned detector performance.
Co-authored a manuscript submitted to ACL Rolling Review (ARR) 2026, contributing experimental design, writing, and result analysis.

Selected Projects

IndicDetect: Cross-Lingual LLM-Generated Text Detection Benchmark Under Review · ACL ARR 2026

Jun 2024 – Present

Constructed a multilingual dataset spanning human- and LLM-generated text in Hindi, Telugu, and Tamil; designed annotation guidelines and inter-annotator agreement protocols to ensure label quality.
Evaluated multiple detection models, including fine-tuned BERT variants and zero-shot GPT-based detectors, across languages; identified cross-lingual performance gaps and proposed transfer learning strategies to address them.
Packaged the benchmark with a reproducible evaluation harness enabling one-command re-evaluation.

Emotion Aid: Emotion Speech Recognition for Disordered Speech Aug – Dec 2023

Developed a deep learning pipeline for emotion recognition from disordered speech; extracted MFCC, prosodic, and spectral features using Librosa and trained CNN-LSTM classifiers on clinical audio datasets with TensorFlow.
Automated the end-to-end evaluation pipeline covering feature extraction, model inference, and multi-class performance reporting, improving experiment reproducibility and reducing manual effort.
Conducted systematic failure analysis across emotion categories and applied targeted data augmentation strategies, including pitch shifting, time stretching, and noise injection, to address class imbalance.
