Wald is involved in the research, development, and operations of real-time information systems at the USGS National Earthquake Information Center.[7] He has developed and manages products such as ShakeMap and the community-science system Did You Feel It?. He is also responsible for developing other systems for post-earthquake response and pre-earthquake mitigation, such as ShakeCast and PAGER.[8] He has also contributed to the USGS Ground Failure product.[9][10] As well as management of these systems, Wald's research also focuses on characterization of rupture processes from complex earthquakes, analysis of ground motions and site effects, and modeling earthquake-induced events.[11]
On top of his publications, Wald is also known for hosting events and giving lectures about geophysics topics, including a "Provost’s Lecture" at Stony Brook University[12] and an EERI Younger Members Committee webinar.[13]
