I am currently a lecturer (~Assistant Professor) in the School of Computing at Macquarie University. Previously, I held a lecturer position in the College of CSE at James Cook University and worked as a research fellow at the University of Sydney and the University of South Australia. I earned my PhD from the University of Sydney, Australia. Before transitioning to academia, I worked in the industry for over 10 years in various technical and leadership roles. My research in Natural Language Processing (NLP) is structured around three interconnected themes: (i) Trust and Safety, (ii) LLM Alignment, and (iii) NLP for Social Good. A central focus of my current work is LLM Alignment with Human Preferences, Values, Cultures, and Safety, exploring how large language models can reason more reliably, reflect diverse worldviews, and operate responsibly in real-world contexts. This involves developing frameworks for value-sensitive, safety-aware, pluralistic, and culturally aligned modeling, ensuring that systems behave in ways that are ethical, contextually appropriate, and aligned with human intentions. I lead the NLP for Social Good Lab - SocialNLP, where we develop safe, aligned, and socially impactful language technologies with real-world applications. I actively publish and contribute to the academic community by serving on program committees, including as Program Co-Chair (WebConf 2026 Web4Good), Senior Area Chair (EMNLP 2025, EACL 2026), and Area Chair for ACL, EMNLP, AAAI, and ACM MM, as well as reviewing for top journals and funding agencies. I am honored to be the recipient of several national and international awards and fellowships, including 5 Best Paper Awards and the DAAD AINet fellowship (2023–2024). My work has been adopted by industry and covered in Australian media.
