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
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.

extent, can the evolution of infectious diseases like Influenza be
- 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).
