Hi! My research interests are in:

  • Forecasting Epidemics: Our long term vision is to make epidemiological forecasting as universally accepted and useful as weather forecasting is today. As was the case with weather forecasting, this will likely take several decades. In the shorter term we are establishing baseline forecasts for the most important forecasting targets (starting with Influenza and Dengue), and creating the infrastructure to curate and compare over time all publicly made forward-facing forecasts (part of the multi-university MIDAS research program).

  • Information and Communication Technologies for Development (ICT4D), and specifically Spoken Language Technologies for Development (SLT4D), which is the term we coined for our own subfield of ICT4D: finding ways to use spoken language technologies (like automatic speech recognition, speech synthesis, and human-machine dialog systems) to aid socio-economic development around the world.

  Our current project, Polly, uses telephone-based viral entertainment to reach low-literate people in Pakistan, familiarizing them with speech interfaces and then introducing them to development-related services. This system has been in use since May 2012, reaching over 165,000 users and fielding over 2.5 million phone calls.

  A previous project, HealthLine, investigated the use of a telephone-based automated dialog system for access to healthcare information by low-literate community health workers in Pakistan.

  • Modeling the evolution of viral epidemics: As part of the multi-university MIDAS research program, we use machine learning, large scale simulations, network analysis and stochastic process theory to try to answer research questions such as:

    1. How, and to what extent, can the evolution of infectious diseases like Influenza be predicted?

    2. How, and to what extent, is the evolution of viral disease like Influenza affected by public health interventions such as vaccination, antiviral drug use, school closures, travel restrictions, etc.

We model the spread of epidemics in the population as well as the evolution of the virus itself, such as changes in its virulence, pathogenicity, drug resistance, or antigenicity (immune escape).
