• Searching the cosmos for new planets: A conversation with Stela Silva, NASA NPP Fellow
    Feb 18 2026
    Stela Silva, Ph.D., an astrophysicist in the NASA Postdoctoral Fellowship Program, has her eye to the sky, sort of. Working with gravitational microlensing, which she says is "the physical phenomenon that happens when we're observing a star and then another star with a planet passes in front of it," and machine learning she looks for signatures of exoplanets. The chance of finding a star is one in a million, Silva says, and she and her fellow researchers look at millions of stars at the same time trying to detect exoplanets. Silva grew up in Brazil, where NASA seemed as far away as the stars she now studies. But she and her grandfather shared a loved of astronomy, and she worked hard toward her dream of being at NASA.

  • The power of machine learning for data analysis: A conversation with Sara Howard, Ph.D.
    Jan 29 2026
    Sara Howard, Ph.D., is an epidemiologist in the Health Studies group at ORAU who earned her doctoral degree in 2025. For part of her dissertation, she used machine learning techniques to analyze data from the National Supplemental Screening Program, which ORAU manages with several partners for the U.S. Department of Energy, to examine the link between chronic obstructive pulmonary disease (COPD) and occupational exposures. While we often think of COPD in the context of smoking, Howard wanted to look at the potential to be exposed to something other than smoking. Her dissertation, An Epidemiologic Study of Chronic Obstructive Pulmonary Disease in the United States, was published by the University of Tennessee in 2025. In this conversation, Howard talks about data in the context of epidemiology and the rising use of Artificial Intelligence and how, when used correctly, it can be transformative for data analysis.
