Having submitted my Ph.D. thesis recently, I am looking for new research opportunities to contribute within the areas of Human-Computer Interaction (HCI) and Ubiquitous Computing (UbiComp) to support health and wellbeing. I have a strong background in mixed-method research design and more than 10 years of experience in designing UI/UX for various industrial sectors.
As a part of a larger project that aims to improve the quality of life of people living with mental illness, two distinct empirical studies were carried out.
- The first study developed a questionnaire-driven conversational agent with state-based and free-form conversational designs and evaluated the accuracy of the self-reports by contrasting 59 participants' responses via each conversational design compared to the paper-based responses to the same questionnaire in a lab setting.
- The second study developed a conversational agent that enabled daily self-report of wellbeing by asking three open-ended questions and an additional questionnaire fortnightly; then evaluated the ecological validity of the system in supporting the self-report of mental health and wellbeing by conducting a four-week mixed-method field deployment study during which 20 people living with affective disorders used the system daily to self-report about their wellbeing.
The goal of this research project was to design a smartphone-based ambulatory heart monitoring system.
- Adopting the user-centered design approach, a series of interviews and co-design workshops with both patients and clinicians were conducted to developed a Requirement Analysis Document (RAD).
- According to the requirements, the prototype of the mCardia system was designed. It included (i) a patient-facing mobile app that enabled real-time reflection on the cardiovascular data such as Heart Rate (HR), HR Variability, and MET level collected via a two-channel Holter device and contextual information, including sleep and step count and (ii) a web app that allowed clinicians to analyze and annotate the ECG data with the contextual information.
Artbox is an NSF-funded app development project with an aim to create an engaging online community of artists and art enthusiasts. The challenge was to engage a diverse group of users, help them make connections with each other, and encourage them to keep coming back to the app.
- Conducted semi-structured interviews with artists and patrons to investigate how they use technology and social media to interact with art.
- Conducted competitor analysis and visited museums, auction houses, and art exhibitions to conceptualize the business model of the app.
- Based on the findings, a unique concept of a local, social, and mobile app was developed and designed.
