Hee-Tae Jung, PhD

Post-Doctoral Researcher

Hee-Tae Jung is a post-doctoral researcher in the AHHA lab. He received his BS from Yonsei University, MS from Stanford University, and Ph.D. from UMass Amherst, all in Computer Science. He takes a holistic, end-to-end research approach with an essential goal of maximizing the overall quality of the rehabilitation service through technology-assisted therapies. Towards that end, he specifically focuses on three paths. 1) He investigates various ways to use artificial intelligence to rehabilitate patients and monitor their impairments/progress. 2) In a human-computer interaction perspective, he attempts to analyze the interaction dynamics of users during technology-assisted therapies in the real-world setting and to understand the room to advance the contemporary state-of-the-art rehabilitation technology. 3) He conducts clinical studies to understand the therapeutic benefit of technology-assisted therapies in routine clinical settings.

Brandon Oubre

PhD Candidate

Brandon is a PhD candidate who joined the AHHA lab in 2017. He received his MS in computer science from UMass Amherst and has been awarded the Barry M. Goldwater Scholarship and an NSF GRFP Honorable Mention. Brandon is interested in the practical applications of machine learning and wearable sensing technology with regard to monitoring and improving human health. His research currently focuses on analyzing human motion in diseased populations (including stroke, parkinsonsism, ataxia, and knee osteoarthritis). His research goal is to develop technologies that can unobtrusively and remotely measure real-world motor performance in order to enable data-driven and patient-centered care.

Juhyeon Lee

PhD Student

Juhyeon is a first-year Ph.D. student in Computer Science. She joined the AHHA Lab in 2019. Her research interest is applying machine learning techniques to health data to improve the mobile health system. Before joining the lab, she worked as a research engineer at Robotics Lab, LG Electronics. She received the M.S. degree from KAIST and the B.S. degree from Ewha Womans University both in Electrical Engineering.

Yunda Liu

PhD Student

Yunda Liu is a first-year Ph.D. student in Computer Science who joined the AHHA Lab in 2019. His research interests include the applications of machine learning in the area of human health in order to make positive clinical impact. He received both his MS degree and BS degree in Computer Science from South China University of Technology.

Noor Mohammed

PhD Student

Noor Mohammed is a first year MS/PhD student who joined the AHHA lab in 2020. He previously received his MS degree in Biomedical Engineering from Wichita State University where he worked towards developing novel electromagnetic near-field epidermal decoder for biofluid phenomena detection inside human body which was funded by NASA. He also received his MS degree in Biomedical Physics and Technology from University of Dhaka and BS degrees in Mechanical engineering from Bangladesh University of Engineering and Technology- the highest echelons of engineering and science educational institutions in Bangladesh. Noor is interested in the multidisciplinary field of bioelectronics which involves practical applications of sophisticated RF electronics, computational modeling, and embedded hardware development. At present, his research is aiming towards the development of novel intrabody power and communication technology for true wearable batteryless body sensor network. His research goal is to introduce new genre of wearable devices where electronics and human will dwell under synchronized symbiosis which he terms as “Symphony of Symbiotronics”. During his respite, he loves to hike, playing guitar, and photography.

Charles Cao

PhD Student

Charles Cao is an undergraduate research assistant who joined the AHHA lab in 2020. He will join the lab as an MS/PhD student in Fall 2021. Charles is currently pursuing a Computer Science BS degree and a Mathematics BS degree at the University of Massachusetts, Amherst. He has also been working at Stratasys, Ltd., an industrial leading 3D-printing company, as a software engineer internship for more than two years. His research interests include designing embedded digital circuits and implementing embedded firmware, which will help people to enhance their life and health. Charles is currently working on battery-less intra-body power transferring sensor networks. As for hobbies, Charles loves coding for interesting projects.
