I am an Associate Professor of Informatics in the Donald Bren School of Information and Computer Sciences at the University of California, Irvine. My research interests lie in the intersection of Human-Computer Interaction (HCI), Computer Supported Cooperative Work (CSCW) and Health Informatics. In particular, I am interested in designing and evaluating interactive systems for clinical documentation, patient-provider interaction and personal information management during chronic care. I received my PhD degree from the iSchool at Drexel University in 2008, and a Bachelor of Medicine degree from China Medical University in 2003.

My research aims to provide empirical, conceptual, and theoretical understandings of information practices in healthcare through in situ examination of how healthcare providers and consumers, e.g. patients and caregivers, interact with computerized technologies in their daily lives or work practices. I have done extensive research exploring sociotechnical impacts and design issues of electronic health records systems, and more recently, patient-facing applications, such as personal informatics tools and chronic disease management systems.

Currently, I am Director of the Undergraduate Minor Program in health informatics. Since Fall 2016, I have served as Vice Chair for Undergraduate Studies in the Department of Informatics.

Portrait of Brian Tran

As we begin to interact with computers in more numerous and complex ways, as well as use automation in contexts that we never have before, how can we best manage the strengths of artificial and human intelligence to enhance people? Understanding technology through the lens of design for usability and productivity can help generate best practices for the effective use of automation.

As an MD-PhD student at University of California, Irvine, I am interested in studying technology use in the healthcare setting and creating tools that will better enable healthcare providers to focus on the most important part of medicine: caring for the patient.

Interests: Human-Computer interaction, Computer-supported cooperative work, Health Informatics, Clinical Documentation Support

Tera Reynolds, MPH, MA

Portrait of Tera Reynolds

I am a Ph.D. Candidate in the Informatics Department at the University of California, Irvine (UCI), under the mentorship of Dr. Kai Zheng. I am broadly interested in how we can improve the design and implementation of technologies that connect, facilitate interaction, and support the independent and collaborative health work of individuals (e.g., patients, general public/citizens) and health professionals (e.g., doctors, public health practitioners). Examples of such technologies include patient portals, Apple Health Records, and COVID-19 Contact Tracing applications. I am particularly interested in examining how we can eliminate digital health disparities. Prior to entering the Ph.D. program at UCI, I earned a B.A. in Biology from Lawrence University, a M.P.H. in Epidemiology and International Health from Boston University, and a M.A. in Information from University of Michigan. I have also worked as a program manager in the public health sector and was a Peace Corps volunteer in South Africa.

Mustafa Hussain, MS

Portrait of Mustafa Hussain

I have a Bachelor's in Computer Science from the University of Utah. But I have the same computer problems as anyone else. Computer problems aren't a matter of intelligence, they're a matter of ergonomics: How well does the interactive software fit the user's needs and expectations?

Physicians have computer problems, too, and that can make the difference between life and death for a hospitalized patient. That's why I'm studying health informatics as a doctoral candidate at UC Irvine: to help physicians help patients, by helping designers to create better interactive software.

Interests: Health Informatics, Computer-Supported Cooperative Work (CSCW), Human-Computer Interaction (HCI), Distributed Cognition

Alessandro Ghigi, MS

Portrait of Alessandro Ghigi

I have several years experience in software analysis, design and development, both at the corporate and at the research level.

I have an extensive experience with back-end (PHP, Python, Node.js, Java Enterprise, Spring Framework, Groovy on Grails, Liferay Portal), and front-end technologies (HTML5, CSS3, SaaS, Bootstrap, JavaScript, jQuery, AngularJS, AJAX, JSP and JSTL).

On the database level, I worked within different environments, including IBM DB2, Oracle, MySQL, PostgreSQL and Microsoft SQL Server. In the past few years, I mainly focused on the management and mainteinance of very large clinical datasets, including a set of parallel activities like data collection, cleansing and loading through ad-hoc scalable ETL procedures, as well as dashboard creation and visualization. Many of these activities involved the use of the Pentaho suite.

Many of my initial job assignments included development of GIS features, or manipulation of GIS data. For this reason, I also have a good experience with the ESRI suite (ArcIMS, ArcSDE, ArcGIS tools), with Google applications (Google Maps API, Google Earth), with Geoserver, and with GIS database support (DB2 Spatial Extender, Oracle Spatial, PostGIS).

I had a chance to widely apply common project methodologies and design patterns, as well as to use UML (use cases, static class diagrams, sequence diagrams) and development tools (Gulp, Grunt, Gradle, Bower, Flyway, Ant, Ivy, JUnit, SVN, Git, Log4J, Eclipse, Jenkins, Trac, Redmine, Jira, Confluence, DocBook, Markdown).

A significant part of my work history has involved leading and working within teams on different projects and interacting closely with clients. Sometimes software has been developed from scratch, starting from the client’s requirements: this gave me a chance also to improve my analytical and problem solving skills and to follow the whole software production lifecycle, from design to testing.
