Does Praying Work? Let’s Pray Data Science Can Help to Answer
For centuries religion has played an important role in shaping our society as a whole and determining the basis of life/purpose for individuals. Whether it’s several daily prayers, Sunday church, or the determination of what time you can eat, religion dictates day-to-day life for many. In this episode, we explore religion’s relationship to health and civic society. Can religious practices deeply increase your quality of life, or even save it? What does the data tell us?

Personalized Treatments: Is That Possible and What Can Data Science Tell Us?
Today we discuss the most important element of our lives: our health. We do so by diving into personalized medicine, or more specifically, personalized (N-of-1) trials – clinical trials in which a single patient is the entire trial. For this episode, we invited two editors of Harvard Data Science Review’s special issue on N-of-1 trials and data science to help us examine all aspects of these clinical trials designed for a population of one person.
Our guests:

To Drink or Not to Drink: Can Data Help Us Decide?
The effects of drinking is a constant news headline. Every month or so, there seems to be a new study released that weighs the benefits and risks of drinking alcohol. Is some level of alcohol good for your health or should everyone completely avoid drinking? On today’s episode we invited two experts with differing views on alcohol consumption to help us examine the data and decide.
Our guests:
Emmanuela Gakidou, Professor of Health Metrics Sciences and Senior Director of Organizational Development and Training at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington.

Differential Privacy for the 2020 U.S. Census: Can We Make Data Both Private and Useful? (Part 2)
For today’s episode we embark on part two of our discussion on the U.S. Census.
Protecting the data privacy of survey respondents has always been a central consideration for the U.S Census Bureau, and throughout its history, many methods have been developed and implemented. For the 2020 Census, the Bureau adopted a new form of privacy protection—differential privacy which was received with mixed reaction. To further understand why the Census Bureau adopted this new form of privacy protection and to help explore the concerns raised about differential privacy, we invited two experts who represent both sides of the debate and who each contributed to the Harvard Data Science Review special issue on the 2020 U.S. Census.
Our guests are:
John Abowd, Associate Director for Research and Methodology, Chief Scientist at the U.S. Census Bureau, and author of the The 2020 Census Disclosure Avoidance System TopDown Algorithm for HDSR.
danah boyd, founder and president of Data & Society, Principal Researcher at Microsoft, Visiting Professor at New York University, and author of Differential Perspectives: Epistemic Disconnects Surrounding the U.S. Census Bureau’s Use of Differential Privacy for HDSR.

Differential Privacy for the 2020 U.S. Census: Can We Make Data Both Private and Useful? (Part 1)
While most Americans have heard of the U.S. Census and understand that it is designed to count every resident in the United States every 10 years, many may not realize that the Census’s role goes far beyond the allocation of seats in Congress.
For this episode, we invited the three co-editors of Harvard Data Science Review’s special issue on the U.S. Census to help us explore what the Census is, what it’s used for, and how the data it collects should remain both private and useful.
Our guests are:
Erica Groshen, former Commissioner of Labor Statistics and Head of the U.S. Bureau of Labor Statistics
Ruobin Gong, Assistant Professor of Statistics at Rutgers University
Salil Vadhan, Professor of Computer Science and Applied Mathematics at Harvard University

Public Opinions on Immigrants and Refugees: Does the Data Inform or Misinform Us?
In this episode we dive into the data on refugees and immigration. American public opinion seems very divided on these issues, but is it really? Is the U.S. more or less welcoming to refugees and immigrants than other parts of the world? How has disinformation influenced politics? Will the U.S. Southern Border, Ukraine, and other potential refugee crises affect the upcoming political elections in the U.S.? We bring in two experts to help discuss:
Professor Katharine Donato holds the Donald G. Herzberg Chair in International Migration at Georgetown University and is Director of the Institute for the Study of International Migration in the Walsh School of Foreign Service at Georgetown University. Professor Donato is also a co-author of the HDSR article: Misinformation About COVID-19 and Venezuelan Migration: Trends in Twitter Conversation During a Pandemic
Scott Tranter, Senior Vice President, Data Science and Engineering at Dynata and Co-Founder of Øptimus Analytics, which was acquired by Dynata in 2021. He is also an investor in Decision Desk HQ, which provides election results data to news outlets, political campaigns, and businesses.
