Computational technologies and ideas are increasingly pervasive in human life. For millions of people around the globe, computers and mobile phones have become the de facto communication medium. At the same time, access to and proficiency in computing technologies is rapidly becoming a major equity issue worldwide.

The Human-Computer Interaction (HCI) and Social Computing faculty at Cornell Tech study the design, implementation, impact and broader implications of computing technologies in everyday human activities. Particular areas of research interest include accessibility, educational technology, Computer Science education, Information and Communication Technologies and Development (ICTD), Computer-supported Cooperative Work (CSCW) and social computing.

Our faculty are committed to working both locally, in New York City, as well as globally, using the city as a base to connect to international networks in business, governance and civil society. We are also committed to practical impact through entrepreneurship and deep engagement with community and industry partners.



Shiri Azenkot

Shiri is an assistant professor at the Jacobs Technion-Cornell Institute at Cornell Tech. She is also an affiliate faculty member in the Computer Science Department at the Technion–Israel Institute of Technology. Her research interests are in accessibility and interaction on new platforms. She conducts this research with a fantastic group of students who are part of the Enhancing Ability Lab, which she directs. Before arriving at Cornell Tech, Shiri was a PhD student in Computer Science & Engineering at the University of Washington.

Nicola Dell

Nicki is an assistant professor at Cornell Tech and part of the  Jacobs Technion-Cornell Institute. Her research interests are in information and communication technologies for development (ICTD), human-computer interaction (HCI) and mobile computing. Nicki’s main focus is on designing, building and evaluating systems that improve the lives of under-served populations in low income regions. To do this, she partners with NGOs and government ministries to create and deploy systems that have a positive impact in the world. Nicki completed her PhD in Computer Science and Engineering at the University of Washington.

Deborah Estrin

Professor Deborah Estrin’s  Small Data Lab focuses on mobile health and small data systems, leveraging the pervasiveness of mobile devices, Internet of Things, and digital interactions for health and life management. The lab develops digital biomarkers to manage chronic diseases, behavioral biomarkers for use in behavior change applications, and immersive recommendation techniques to create a more user-centric form of personalization. A significant focus is on approaches that support varied and dynamic preferences for data sharing. The lab contributes to open source projects including Open mHealth, ResearchKit™ and ResearchStack.

Mor Naaman

Professor Mor Naaman’s  Social Technologies Lab has been looking at technologies to support the peer economy by increasing awareness, coordination and trust. Communities in urban environments — and underserved communities in particular — could benefit from the positive economic and social outcomes offered via collaborative consumption services. For example, one project examines how trustworthiness is established in services like Airbnb, and another project uses location data traces to reinvent how people socially interact with their local communities.

Tapan Parikh

Professor Tapan Parikh’s Represent group has been developing mobile phone-based information services in India that allow small farmers to access and share timely and pertinent agricultural advice. Based on the results of a randomized controlled trial (RCT) and over five years of deployment, this intervention has been shown to have a significant impact on farmer decision-making and productivity. The system has now been scaled across India through a startup company founded by Prof. Parikh and his students, currently serving hundreds of similar groups across India.
