Hello, I'm Yuanyuan.

I am a UX researcher, applying Socio-technical Systems Theory and mixed methods in understanding user behaviors in healthcare. I received a PhD degree on Human-centered Computing in the department of information systems at the University of Maryland Baltimore County. I was advised by Dr. Helena Mentis in the Bodies in Motion Lab. I have been a visiting student in the Ubiquitous Computing Lab at University of California, San Diego (UCSD) from 2017 to 2019. I am passionate in understanding and translating novel technologies into healthcare.

Résumé

Projects

UX Research

XR for Surgical Telementoring

Designed an extended reality envrionment for remote knowledge sharing in trauma surgery.

Knowledge Sharing in Surgical Telementoring

Identified challenges in remote knowledge sharing in a simulated surgical training.

Augmenting Expertise in Surgical Training

Designed and evaluated a touchless video annotation system for knowledge sharing.

Understanding Language Use in Surgery

Communication analysis of in-situ laparoscopic surgeries in a teaching hospital

Touchless Interaction in Imaging Manipulation

Investigated the efficacy of touchless devices in surgical imaging manipulation.

Gait Detection for Slow Walking Population

Compared the accuracy of three tri-accelerometers among slow-walking population

OHC Contexts for Health Outcomes

Conducted a literature review on the efficacy of OHCs as an intervention for health outcomes.

Data Science

Analysis for Covid-19

Leveraged EHR and enterprise data to identify covid-19 patients and assess vaccine uptake and vaccine efficacy

Ventilator Usage for Capacity Planning

Identified and tracked mechanical ventilator usage for capacity planning.

Connecting CBO Data and EHR Data

Denormalized CBO Database and integrated CBO data with EHR for SDOH analysis.

Case Manager & Length of Stay

Identified the association between the patient being seen by a case manager and his/her length of stay.

Echocardiogram & Length of Stay

Determined if echocardiogram prolongs the length of hospital stay and ways to improve.

LSTM-Attention Model for Pragmatics Research

Demonstrated the feasibility of using deep learning technique for identification language use patterns.

Outcome Prediction with Clinical Trials Metadata

Employed clinical trials metadata to classify primary outcomes before trial implementation.

OR Collaboration Data for Predicting OR Time

Developed a predictive model for OR times to support OR personnel assignment.
