Profile

I received a Master of Science (M.Sc.) degree at KTH Royal Institute of Technology in Communication Systems (ICT) and a Master of Arts (M.A.) degree at Uppsala University in Computational Linguistics (NLP). I am now pursuing my PhD at Stockholm University, focusing on the area of AI + Education. My significant interest is applying modern pre-trained language models in educational scenarios. I have published papers about applying word embeddings in collaborative learning and BERT in auto-grading projects in AIED, EC-TEL, ICALT, MIS4TEL and will continue my research journey with other exciting models, such as GPT and DALLE.

Before my academic career, I worked at Ericsson 5G Incubator(Sweden) with innovation projects in the Open Source world. I mainly took part in the ONAP(Open Network Automation Platform) and O-RAN(Open Radio Access Networks). I also worked with Digital Services and Cloud transformation projects. Those cloud techniques have also been applied in my research, .eg., designing high-performance AI/ML APIs based on large language models in a cloud-native way.

I love travelling and playing with blockchain smart contracts during my spare time. I am writing posts about AI & NLP, cloud (MLOps), and Web 3.0 in this blog.

Working Experience

I am currently a PhD student and researcher at Stockholm University. I also worked on multiple projects at Ericsson AB, Sweden, for five years before my academic life.
