13 WINTER/SPRING 2018 B enne Holwerda has snagged some coveted time using the famous Hubble Space Telescope, and he doesn't even have to budge from campus to use it for his research. The associate professor of physics and astronomy is one of two Kentucky university researchers who competed for and successfully won time on the telescope for this year's 25th cycle of observations. "The award of Hubble observing time is an exceptional accomplish- ment worthy of recognition," wrote Kenneth Sembach, director of the Space Telescope Science Institute, in announcing the honor. The STSI carries out the scientific program for the Hubble instruments, which were built under the auspices of the National Aeronautics and Space Administration and the European Space Agency. The space telescope, launched in 1990, is considered a valuable asset for astronomers studying the universe. Scientists using data and photos from its earth orbit have published more than 15,000 scientific papers. Holwerda will use his information from the "schoolbus-sized" telescope for three research projects, and he'll receive alerts when it is observing the data he seeks for each of those. The astronomer is looking at two overlapping galaxies and studying the role of dust in the energy of the small galaxies. He examines the "smudgy smog that is interstellar dust — a byproduct of stars that die or go supernova. It affects how the galaxy looks … I'm looking for how much the stars get reddened or dimmed by dust." "I'm using the background galaxy as a light-table  —  a projector to highlight the foreground structures," he said. Holwerda also plans to map the luminosity, size and color distribu- tions of star clusters in and around the disk galaxy UGC 2885, which late scientist Vera Rubin discovered in the 1980s. Holwerda met her and hopes that in doing this work his team can make a Hubble Space Telescope image as a tribute to her work.

The selection as a CHOT site includes a three-year agreement of up to $500,000 per year in funding from the NSF and industry partners to support the implementation of evi- dence-based strategies within health care organizations. "CHOT members are working to solve health care challenges three to five years ahead of the rest of the industry ," said Christopher E. Johnson, professor and chair, Department of Health Man- agement and Systems Sciences in the School of Public Health and Information Sciences. "We are trying to project into the future the direction of health care. Interdisciplinary applied research will be the catalyst for solving problems and making changes." Johnson will serve as the UofL CHOT site director, along with J'Aime Jennings. UofL CHOT is working to secure local industry partners and organizations to join the center through a $50,000 yearly commitment for three years. Passport Health Plan, Sanofi and UofL Hospital are among those who have signed an agreement. Potential projects include interven- tions for those facing opioid addictions and the role of behavioral health in helping individuals secure employment; analyzing readmission in the long-term care population; using health informa- tion technology to improve access to services; and evaluating use of artificial intelligence as a diagnostic tool.
