Marcelo Simas, PhD, has 20 years of experience in survey research in social sciences, travel behavior measurement, and data science applications. This includes systems responsible for aggregating data from tens of thousands of smartphone app users and hundreds of thousands of web survey participants, as well as data warehouses for survey research data, online statistical data processing, and data visualization. Simas serves as the technology architect on several household travel surveys for regional and state transportation authorities. He leads systems development and integration to support data collection as well as data management-related activities.
For NSF’s Survey of Doctorate Recipients, he led the effort to design and implement a secure research data warehouse (RDW) to support project activities. The implemented RDW uses modern open-source based tools and technologies and is designed to support multiple data collection cycles. For the USDA’s Second National Household Food Acquisition and Purchase Survey (FoodAPS-2), Simas oversaw the design and implementation of native smartphone apps used to streamline data collection by allowing survey participants to use their own devices.
