This amazing picture was taken by my wife at Skyline Trail, Mount Rainier, 2023.
PS: Prepare enough water for this trail but make sure you are not the one carrying it.
My name is Tiantian Feng, and I completed my Ph.D. in the Computer Science Department at University of Southern California in 2024, and I am currently a postdoc researcher in SAIL lab at USC. I am fortunate to be advised by Professor Shrikanth Narayanan. I will be soon joining the Chinese University of Hong Kong, Shenzhen (CUHK-Shenzhen) as an assistant professor, and I am activity recruiting prospective students to join my research group. Feel free to send me your information at tiantiaf@gmail.com.
My research is about AI+Human Lifespan+Digital Health, and my approach is full-stack AI that includes sensor technology, machine learning, and human experiences to understand natural human conditions in healthcare applications across life span. Notably, I have involved in projects studying children with autism, workplace behavior of hospital professionals, aging population with cognitive decline, people with hearing loss, and mental health (e.g. Postpartum depression (PPD)).
I also have a particular interest in building technology that is private and broadly accessible. I have been focused on developing datasets and benchmark that are shareable across different community. My research invovles applications such as speech understanding, wearable computing, multimodal understanding, and bio-signal processing, etc. Additionally, I have hands-on experience in industrial sensor design and deploying sensors in research studies. I have interned at both Meta and Amazon as the research scientist.
Don’t hesitate to contact me if you would like to collaborate.
