Clark has published more than 100 peer-reviewed journal articles, book chapters, and comments, and his combined work has been cited more than 5,000 times.
[3] Clark's research explores the epi-demographic history of populations living in Africa and develops new mathematical and statistical methods for demography and epidemiology.
The openVA suite is freely-available, open-source software that implements all commonly-used tools to automate cause ascertainment using data from verbal autopsy interviews.
The openVA Pipeline integrates the cause-ascertainment algorithms into an automated workflow that moves deaths with verbal autopsy from an Open Data Kit (ODK) server through cause assignment and on to the District Health Information System version 2 (DHIS-2).
It is feasible for countries without traditional vital statistics systems to implement verbal autopsy and use these tools to fully automate cause ascertainment and descriptive analysis of the burden of disease.
