Recent news

  • Dr Paliy receives Fulbright Scholar award:

    Dr Paliy has been selected as Fulbright Scholar for the 2022-2023. He will travel to Giza-Cairo in Egypt to work on a collaborative project with his colleague, Dr. Laila Hussein. Together they will investigate how supplementing diet of Egyptian teenagers with prebiotic fiber can improve children gut health and affect their intestinal microbes.
