This project is the first comprehensive examination of African North Americans who crossed one of the U.S.-Canada borders, going either direction, after the Underground Railroad, in the generation alive roughly 1865-1930. It analyzes census and other records to match individuals and families across the decades, despite changes or ambiguities in their names, ages, “color,” birthplace, or other details.

Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to. They were used to facilitate the city’s development in hilly areas. Students may be familiar with the Morningside Park retaining wall , present immediately East of the Columbia campus. Retaining walls facing streets are mapped and inspected. Not so retaining walls supporting soil at back yards. Because the NYC Building Department is not aware of the presence of most, they are not inspected and left to decay. A fatal collapse occurred in October 2020.

New York State regulates construction and demolition waste (CDW)—its generation, recycling and reuse—and collects all data on CDW from private waste haulers and transfer stations/recycling facilities. There is no city source of data for CDW. For the city to innovate policy with respect to CDW, which is a source of embedded carbon, by leveraging its capital program to close material loops, generating environmental sustainability and financial sustainability benefits, it is important to understand where CDW goes after the demolition process through the transfer and recycling processes.

NYC DDC has initiated a machine learning project to develop predictive model for estimating cost of project and work items. Using the latest technique in Machine Learning and Advanced Statistics, NYC DDC to develop a model that predicts the cost of future and active projects and construction work items in different phases of the lifecycle of the project based on historical data. DDC has partnered with Microsoft who is providing the proof of concept guidance and making tools available for the proof of concept development. DDC is seeking assistance of a data scientist from the Town and Gown program to develop the model.

New York Presbyterian/Columbia University Irving Medical Center (NYP/CUIMC) serves a high number of racial/ethnic minority and low-income patients. In this project, we will create a data repository of all patients who have completed a universal screen in a clinical encounter for social determinants of health, including food insecurity. The scholar will handle large datasets extracted from the medical record for database creation and data visualizations. The dataset will include patient demographics, food security, and clinical outcomes. This data resource will allow the scholar to partner with researchers to examine predictors of food insecurity, clinical courses, and health outcomes among a large population of patients, including a time period prior to the COVID-19 surge in New York City. The project will be co-mentored through the members of the University-wide Food Systems Network, a novel collaboration of researchers at the Medical Center, Earth Institute, SIPA, and Teacher’s College.
