Hi! My research interests are in:
- Forecasting Epidemics:
The long term vision of our Delphi research group 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 a long time. In the shorter term, we select high
value epidemiological forecasting targets (currently Influenza and
Dengue); create baseline forecasting methods for them; establish metrics
for measuring and tracking forecasting accuracy; estimate the limits of
forecastability for each target; and identify new sources of data that
could be helpful to the forecasting goal.
challenges: We have participated,
and done very well, in all epidemiological forecasting challenges organized by
the U.S. government to date: Influenza 2013—2014 (CDC); Chikungunya 2015
(DARPA); Dengue 2009—2014 (White House OSTP); Influenza 2014—2015 (CDC);
Influenza 2015—2016 (CDC); Influenza
2016—2017 (CDC, ongoing).

- 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 and India, familiarizing
them with speech interfaces and then introducing them to development-related
services. First deployed in Lahore in
May 2012, Polly reached over 165,000 users all over Pakistan and fielded over
2.5 million phone calls in 8 months. In
2013 we launched Polly in Bangalore, India, and it ended up spreading virally
to West Bengal, New Delhi and other areas of India. In March 2015 we deployed Polly in Guinea,
for person-to-person spreading of approved Public Health messages about Ebola
in many languages, in collaboration with the US embassy in Conakry. In 2016, in collaboration with Information
Technology University (Lahore) we launched two new services in Pakistan: Baang, a voice-based Reddit, and Sawaal, a voice-based quiz game.
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.
