Arun’s research in the area of digital enablement of supply chains has examined how IT resources and capabilities can be combined with other resources and capabilities and with interfirm governance practices to a) promote information and knowledge sharing, b) develop effective supply chain coordination, and c) create IT business value. His research program in this area has involved close collaboration with United Parcel Services, Georgia Pacific, Hewlett-Packard, and SAP.
Arun’s research in the area of digital strategies for IT business value has examined how IT is fundamentally changing business systems and the role of IT strategy, digital strategies for the creation and appropriation of business value, and the performance impacts of IT at different levels of analysis (networks, firm, processes).
Arun’s research in the area of Software Development and Project Management has examined how innovations in software development technologies and methodologies can address problems in software development/maintenance; how formal and informal controls can mitigate different risks in the development process; and how complex software development projects that require collaboration across expertise, role, and cultural boundaries can be effectively managed. These projects have been in collaboration with development groups, Fortune 100 firms with large IT organizations, and leading offshoring vendors and their client firms.
Arun’s research in the area of Information Technology implementation and Use has examined the adoption, assimilation, and use of IT innovations in a variety of organizational and societal contexts, with a lens towards addressing a key problem and generating value. Within the organizational context, he has examined the adoption and use of computer-aided software engineering by individual developers, the adoption and use of executive of information systems by senior executives, the use of electronic medical records by physicians, and different types of use of CRM systems by sales and marketing personnel in hi-tech environments. At the societal level, he has studied the growth in the diffusion of internet technologies, the adoption and use of free internet technologies, the utilization of e-health kiosks to change infant healthcare practices in rural India, and the use of mobile health technologies in the United States and India. He has brought to bear a variety of cross-disciplinary theoretical perspectives including diffusion of innovation, technology acceptance, individual and social cognition, sense-making, social network analysis, organizational innovation, service innovation, and process innovation to inform these studies. Many of these studies have been in collaboration with scholars across disciplinary lines (e.g., medicine, public policy, social networks) and with organizations and government agencies in different countries.
Arun’s research in the area of Information and Communication Technologies for Development (ICT4D) has examined (1) how to address digital inequality in the United States, (2) how ICT interventions can be used to improve health literacy and reduce infant mortality in rural villages in India, and (3) how cost-effective telemedicine and mHealth solutions can be deployed to broaden access to healthcare services and improve the well-being of poor and marginalized people in rural India.
Arun’s work on research methods has examined 1) the specification and validation of measures for structural equation models and composite models (particularly Partial Least Squares) and 2) parameter recovery, statistical power, and predictive utility of Partial Least Squares with composite-based populations.
Arun’s research in the area of Health IT has examined the use of EMR and CPOE systems in the clinical processes of large hospitals, the design of cost-effective telemedicine solutions to broaden access to healthcare in rural India with limited healthcare and technological infrastructures, mobile-health (mHealth) services channel preferences, the cost and quality impacts of health IT capabilities in U.S. hospitals, the search mechanisms that drive IT-enabled innovation in U.S. hospitals, and the role of patient-physician online communities in China for physicians to send signals to patients and for patients to provide feedback on physicians. These projects have been in collaboration with large hospital systems in the United States and India and with scholars across disciplinary traditions and countries.
