Doctoral Students

The 2CI Initiative is a five-year program to add at least 100 new faculty lines between 2010-2015. Its primary goal is to build nationally and/or internationally recognized strength and critical mass around common research themes to enhance Georgia State University’s overall quality, interdisciplinary richness, and competitiveness.

Langtao ChenLangtao Chen is a Ph.D. candidate in Computer Information Systems at the J. Mack Robinson College of Business. He received a 2CI Fellowship from 2012 to 2015. His current research areas are healthcare IT and big data analytics. He is writing a two-essay dissertation, with one essay already completed and submitted to a top IS journal. Overall, he is making excellent progress toward the degree and toward publications. The first essay is a study of the intellectual structures of the healthcare informatics and healthcare IT scholarly communities. It examines the prominent healthcare IT themes over a 20-year period and the most influential thought leaders of these sub-communities. The paper was presented at Georgia State University at a colloquium in fall 2014. It has also been presented at the University of Georgia and Baruch College, CUNY.

His second essay is a text-mining paper that looks at a dozen or so self-managed online healthcare communities. He has gathered 2.3 million documents and, using text-mining techniques that are available on the Web or ones he has devised himself, testing a causal model that links diagnosis to treatment options and to outcomes. He is looking at the emotional support given and received as well as purely informational exchanges.

Amrita GeorgeAmrita George is in her first year of the CIS doctoral program. HIT fellowship was granted to her in December 2014. Under the guidance of Dr. Balasubramaniam Ramesh, she has since been working on two projects within the domain of HIT development.

Project 1: Cloud based Healthcare IT solutions

Recent innovations in virtualizations and Internet services has resulted in tremendous growth of cloud computing. The key benefits of cloud computing are greater storage, cost reduction, collaborative solutions, and access to innovative services such as analytics. Healthcare IT organizations are increasingly exploring the use of cloud computing to develop affordable quality IT solutions. However, such implementations also involve significant challenges such as security breaches, service unreliability & unavailability, incompatible integration & interoperability, and regulatory compliance. These challenges have prevented wide-spread adoption of cloud based Healthcare IT solutions. Our study examines the enablers and inhibitors to adopting cloud based Healthcare IT solutions.

Technology-organization-Environment Framework that has been used widely to evaluate the adoption of various technology innovations (such as e-business, ERP, etc) will be used as a theoretical lens to examine enablers and inhibitors of cloud adoption for healthcare IT solutions. Further, this research seeks to develop and evaluate a product/platform development framework that will facilitate the creation of cost effective healthcare IT solutions on the cloud. Semi-structured interviews of practitioners involved in the deployment of healthcare IT solutions will provide the primary source of data for the study. Based on the results of a detailed literature review, we are currently finalizing the design of the empirical study of practitioners involved in the deployment of healthcare IT solutions. Data collection and analysis will proceed in an iterative fashion during Summer 2015.

Project 2: Agile Development in HIT development

Agile Systems Development (ASD) is a light-weight systems development approach that promotes adaptive planning, evolutionary development, continuous improvement, and flexibility in responding to change. While agile development has grown exponentially in many industries, their adoption in HIT development is very limited. While agile development provides organizations the ability to respond to turbulence in the markets for products and services, it also impedes their ability to meet regulatory and security requirements. The Technology-organization-Environment Framework provides an appropriate theoretical lens to study such conflicts.

Our study seeks to develop a conceptual framework to explain how HIT development organizations address conflicting demands. A multi-site case study of HIT development organizations will provide the primary data needed for the development of such a framework. Based on a detailed literature reviews, we are finalizing the design of the empirical study. Data collection and analysis resulting in the development of the conceptual framework are planned for Spring 2015.
