Funded RA Positions Available in Mixed-Methods (Quantitative & Qualitative) Health Informatics Research

Prof. Sunghoon Ivan Lee, Director of the Advanced Human-Health Analytics (AHHA) Lab at UMass Amherst, is accepting a PhD student (with full funding) for Fall 2022. Please read the project description and necessary skillsets below. If interested, please reach out to Prof. Lee at along with your CV. You will also need to apply to the Ph.D. program in the College of Information and Computer Sciences (Deadline: 12/15). Applicants are encouraged to specify that they are interested in working with Prof. Lee in their SOP. Please also visit the lab webpage:


Explicitly focusing on individuals undergoing long-term rehabilitation – such as stroke survivors and TBI survivors – we are interested in how personal health information could help patients better engage in at-home rehabilitation and self-management of their conditions outside the clinic. Various health-related personal information has been studied, but current solutions primarily focus on tracking patients’ history of compliance behavior and training performance. We are currently investigating how machine learning-generated personal information with inherent uncertainties could help patients establish stronger engagement to long-term rehabilitation and positively affect their compliance behavior. I am specifically looking for students who are passionate about at least one or preferably combination of the followings: 1) designing machine learning algorithms to extract clinically relevant information from data obtained from patients’ home settings via wearable and mobile devices, 2) investigating real-world needs of the stakeholders (i.e., patients and clinicians), and 3) design a technological solution to provide the information back to the stakeholders (e.g., mobile app to visualize personal data).

Knowledge, Skills, and Abilities

The Ph.D. students will closely work with Prof. Lee and other team members in a weekly basis. They are expected to have excellent oral and written communication, creativity for algorithm and/or qualitative anlaysis, and teamwork spirit. I prefer candidates with at least one of the following skills:

  • Strong understanding and preferably prior experience in human-centered design approaches, such as semi-structured interviews, participatory design with clinicians and patients, and in-lab and deployment studies.
  • Strong understanding of the fundamentals of machine learning and its implications to domain specific data. Having experience in analyzing wearable time-series data to construct regression or classification models is a plus.

Note that we do not require applicants to have domain-specific knowledge in rehabilitation medicine. I welcome students with diverse backgrounds who have strong interests in the subject matter & enthusiasm to advance healthcare using technologies.
