“In today’s world, information is the most critical tool in everything we do,” says Professor Kai Zheng. As a leading expert in the field of health informatics, he is pioneering new ways of harnessing and utilizing information to improve health outcomes and maximize quality of life. “At its heart, my work is about understanding people: physicians, nurses, pharmacists, patients and their caregivers,” he says. “I want to find out how they interact with information through technology and how we can make that interaction more enjoyable and effective.”

Dr. Yunan Chen

Portrait of Dr. Yunan Chen

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.

Brian Tran

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. student in the Informatics Department at the University of California, Irvine, with an interest in health informatics. Under the advisement of Dr. Kai Zheng, I am currently investigating how we can improve the way that we present clinical information (e.g., laboratory results) in patient-facing technologies (e.g., patient portals) to better meet the needs of patients. I have received a B.A. in Biology from Lawrence University, a M.P.H. from Boston University School and a M.A. in Information from University of Michigan. In addition, prior to entering the PhD program, I worked for 3 years as a program manager in the public health sector and was a Peace Corps volunteer in South Africa from July 2007 through September 2009.

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

I am a Ph.D. student in the Informatics Department at the University of California, Irvine. Prior to that, I received my Bachelor degree in computer science at the University of Minnesota. I am interested in retrieving useful information from unstructured natural language data such as EHR, social media posts and online health community journals. My previous projects include retrieving supplement use status from clinical notes using machine learning models and understanding how expressive writing contributes to users' staying in online health communities.

Mayara Costa Figueiredo, MS

Portrait of Mayara Costa Figueiredo

I am a Ph.D. student in the Informatics Department at the University of California, Irvine, under the advisement of Dr. Yunan Chen and Dr. Kai Zheng. I am interested in how technology can be used to improve healthcare and assist patients, especially underserved populations and people with chronic conditions. I am currently investigating how patient-generated health data can be used to support patients and improve patient-provider interaction. My current project focuses on understanding the uncertainties women face when using self-tracking for fertility care and how to better support them. I have a B.S. and a M.S. in Computer Science from Federal University of Pará, Brazil, and prior to my PhD I have worked for 5 years as an IT analyst and project manager in the same university.

Staff

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.

Dr. Yu Chen

Portrait of Dr. Yu Chen

As a researcher, designer, and engineer, my research is mainly grounded in Human-Computer Interaction, Computer Supported Collaborative Work, Ubiquitous Computing, and Health Informatics. I aim to apply social psychology theories in mobile technologies to enhance human welfare. I first gather user requirements using qualitative methods, and then implement system interfaces and functions with standard design and development tools. I evaluate the systems by conducting longitudinal studies using a mix of quantitative and qualitative methods. I received my Ph.D. in Computer and Communication Sciences from the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland in 2015. My supervisor was Dr. Pearl Pu, the director of Human Computer Interaction Group. Before that, I received my Master's degrees in Security and Mobile Computing from both Aalto University in Finland and the Norwegian University of Science and Technology (NTNU) in Norway in 2010 and Bachelor's degree in Information Security from Huazhong University of Science and Technology in China in 2008. I was a research intern in the headquarter of Nokia Research Center in Helsinki in 2009 and 2010.
