During my PhD study, my research focus was initially on designing and implementing novel machine learning and deep learning algorithms for recommender systems that can handle massive datasets. Recently I have been more interested in natural language processing research, especially its application within financial markets. Moreover, I am quite interested in the interaction of computer vision and NLP, which I think is quite promising. My research works have been published at top machine learning conferences KDD, ICML, NeurIPS, AISTATS and CVPR. I also review papers regualrly for ICML, NeurIPS to contribute back to the community. I was jointly advised by Professor Cho-Jui Hsieh and Professor James Sharpnack.
