I am a postdoctoral fellow at the Department of computing science at Umeå University, Sweden. I received my Ph.D degree from the Umeå University with focus in privacy-guaranteed machine learning with big data. Before that, I got a M.Sc degree in Computer Science, Kyungpook National University in Korea with focus on NLP and Machine Learning. My work has been primarily focused on knowledge - both acquiring knowledge from text, multimodal data, and using structured knowledge to power downstream applications. I am a reviewer for journals/conferences including TheWebConf, ECAI, ICDM, PAKDD, SSR, SC2, COSE (Computer & Security), TPAMI.

My research has been involved around ML/DL solutions for ubiquitous data processing and analysis. Ubiquitous data refers to the various types of data available via IoT applications and user generated contents in daily activities (e.g., multimodal reviews, user activities on mobile devices, etc.). These data are not only scarce, ubiquitous but also located in different devices, locations, and belong to different users. To user generated content research, I have been working on privacy-guaranteed models for protecting user privacy while learning on their data. To data analytics, I have been proposing KaPPA and INFRA, two different analytical frameworks to project personal data for data analytics with new privacy-aware learning methods in the frameworks. Last but not least, different neural models were proposed by us in different research including (but not limited to) ppRNN [6], dpUGC [5], SGTN [4], MG-PRIFAIR [3], MGTN [1], Cformer [7]. These models play important roles in processing ubiquitous data which are not only scarce but also complex in most of the cases.

Collaboration is an important part of my work and I am a board member and publication chair of Vietnam Language and Speech Processing (VLSP) association organizing an International Workshop annually. VLSP encourages research in related areas by providing high quality datasets and letting the research community work on them via data challenges. Locally, I work with a project in Robust Machine Learning that studies new algorithms and neural methods to enhance robustness of ML based applications in multimodal data (e.g., the combination of textual data, visual data, graph data) tasks. Most recently, our work involves applications in healthcare, food of interest, and security on the edge cloud.
