Welcome! 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.
Ř Epi-Forecasting 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).

Forecaster” for 2015-2016.
- Information and Communication Technologies for
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.
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
a voice-based Reddit, and Sawaal, a voice-based quiz game.
investigated the use of a telephone-based automated dialog system for access to
healthcare information by low-literate community health workers in Pakistan.
