I am on sabbatical in Israel through end of June 2018, so am not able to meet or take on any new engagements.

Do you have a question about 10601A/C for Fall 2018?  Please read this.

Welcome!  My interests are in:


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, winner); Influenza 2015—2016 (CDC, winner);  Influenza 2016—2017 (CDC, winner).

Ř  Try our operational, geographically detailed, real time flu nowcasting service.

Ř  Try our operational, weekly updated flu forecasting.

Ř  We are part of the multi-university MIDAS research group.

Ř  December 2016: CDC has just named us “Most Accurate Forecaster” for 2015-2016.

Ř  October 2017: We did it again!  Our two systems took the top two spots out of 28 submissions in the 2016-2017 flu challenge.


Ř  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.

Ř  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.
