About Me

Welcome to my homepage! My name is Bojian Hou (also Bo-Jian Hou), a postdoctoral researcher of Department of Biostatistics, Epidemiology and Informatics at the University of Pennsylvania advised by Prof. Li Shen.

I received my B.Sc. and Ph.D. degree in the Department of Computer Science at Nanjing University in 2014 and 2020 separately. I was a member of LAMDA Group led by Prof. Zhi-Hua Zhou during my doctoral study. My Ph.D. supervisor is Prof. Zhi-Hua Zhou.

My research interests mainly focus on trustworthy AI, optimization for AI and AI for science. Specifically, they include:

• Fairness Learning: developing fair and unbiased machine learning algorithms.
• Interpretability: studying the interpretability of the black-box machine learning models.
• Feature Evolvable Learning: studying learning scenarios where data features evolve.
• Semi-Supervised Learning: learning models from both labeled and unlabeled data.
• Online Learning: learning models continuously from online streaming data.
• Natural Language Processing: developing and applying large language models.
• Biomedical Data Mining: developing machine learning methods to analyze biomedical data (especially for Alzheimer’s disease and related dementia (ADRD)).

I am seeking faculty positions for the 2024-2025 academic year, with a focus on computer science, data science, biomedical informatics, and related fields. I welcome inquiries from interested institutions.
