• The struggle is worth it: A conversation with Kalidas Mainali, Ph.D., ORISE postdoctoral fellow at the USDA ARS

  Kalidas Mainali, Ph.D., is an ORISE postdoctoral fellow at the U.S. Department of Agriculture Agricultural Research Service. He is stationed at the USDA ARS Eastern Regional Research Center in Wyndmoor, Pennsylvania, where Mainali is studying methods for creating biofuels and other valuable resources from agricultural waste. Mainali is a native of Nepal who also studied in Scotland, so he brings a wealth of world-wise experience to his research, but says that he ultimately decided to pursue his Ph.D. in the United States because of the extensive research opportunities available here. In this conversation, Mainali talks about his educational journey, his relationships with his mentors, and his plans for the future.

• Introducing Natasja Brown, co-host for the 2025-26 Albert Einstein Fellowship podcast series

  The 2025-26 cohort of Albert Einstein Distinguished Educator Fellows has begun their fellowship year in Washington, D.C. Natajsa Brown, an educator from Ocean Springs, Miss., is serving as co-host for this cohort's series of ORISE Featurecasts. In this conversation with host Michael Holtz, Brown introduces herself and what led her to apply for the AEF. As you'll hear, it's going to be a great season of conversations. Welcome, Natasja! Natasja Denise Brown is a passionate science educator with twelve years of experience teaching students from 7th grade through the university level. Most recently, she has taught high school accelerated biology at Ocean Springs High School in Mississippi while also serving as an adjunct instructor at Mississippi Gulf Coast Community College, where she taught Biology I and II. Her dedication to students extends far beyond the classroom. She founded the middle and high school Science Bowl teams at her school, coaching them for the past six years to achieve first place or runner-up finishes nearly every year in the state. In the most recent national competition, her team ranked among the top 32 in the nation. In addition, she has served as the freshman student council sponsor, advised the Red Cross Club, and contributed to the National Honor Society faculty committee. The Albert Einstein Distinguished Educator Fellowship Act gives the U.S. Department of Energy (DOE) the responsibility for managing the Albert Einstein Distinguished Educator Fellowship. The DOE Office of Science’s Office of Workforce Development for Teachers and Scientists (WDTS) manages this program for DOE in collaboration with the Oak Ridge Institute for Science and Education (ORISE) and the partnering Federal agencies, which, at the time of this recording, included the Department of Defense (DOD), the Department of Energy (DOE), the Library of Congress (LOC), the National Aeronautics and Space Administration (NASA), the US Geological Survey (USGS), the Department of Homeland Security (DHS), and the National Science Foundation (NSF). The DOE sponsors five placements in congressional offices. To learn more about the Albert Einstein Distinguished Educator Fellowship, visit https://science.osti.gov/wdts/einstein.

• Science isn't science until you share what you've found: A conversation about the value of scientific peer review

  Peer review evaluation of an individual or groups work by another individual or group with expertise in the same field or a related field. Peer reviewed work may include proposals to conduct scientific research, ongoing research itself, or a submitted papers based on ongoing or completed research. In this episode of the ORISE Featurecast, host Michael Holtz talks to Colleen Iversen, Ph.D., a former ORISE research participation program participant who now serves as a peer reviewer for ORISE. Their conversation covers the importance of the peer review process to the advancement of science, the newly developed ORISE Peer Review Resource Hub, the need for young investigators to become peer reviewers, and how peer review makes you a better scientist and proposal writer. Access the Peer Review Resource Hub here: https://orise.orau.gov/peer-review/resource-hub/index.html Dr. Colleen Iversen is an ecosystem ecologist who uses a variety of field and laboratory techniques to understand and predict how ecosystems – from upland forests to flooded peatlands to thawing Arctic tundra – are shaped by their environment. Colleen is a Distinguished Staff Scientist in the Environmental Sciences Division at Oak Ridge National Laboratory, Group Leader of the Plant-Soil Interactions group, and Director of the NGEE Arctic project. She is an Editor at the international plant journal New Phytologist, and she was an elected Early Career Fellow of the Ecological Society of America and a member of the inaugural cohort of ‘New Voices’ at the National Academies of Sciences, Engineering, and Medicine. Colleen sees science communication as the foundation for a shared understanding of society’s future, and she has shared her scientific vision on Public Radio International’s ‘Science Friday’, and in the Alda School’s ‘Flame Challenge’, as well as in organized symposia, sessions, and workshops.
