KU, Haskell students to present research projects April 26

LAWRENCE — Research relating to cancer, genetics, medicinal plants and social relationships will be presented at the 11th annual University of Kansas-Haskell Indian Nations University Research Symposium.

Twenty-nine students are expected to present posters of their science and engineering research from 4 to 6 p.m. Tuesday, April 26, at Haskell Indian Nations University in Tecumseh Hall.

This year’s event is sponsored by the Bridges to the Baccalaureate Program, one of four programs that encourage underrepresented students to pursue research careers in biomedical science. The other three programs are the Research Initiative for Scientific Enhancement Program at Haskell, the Initiative for Maximizing Student Diversity Program at KU and the Post-Baccalaureate Research Education Program at KU.

The presenters include undergraduate and graduate students at both universities. Five Haskell and 24 KU students are presenting their work.

Following this year’s poster presentation will be a reception honoring Marigold Linton, KU’s director of American Indian outreach in the Office for Diversity in Science Training. Earlier this year, President Barack Obama presented Linton with a Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring.

Symposium participants are listed by hometown, level in school, major, Native American heritage (if applicable), science diversity program, parents’ names, high school, project faculty adviser, project title and brief description of the project.
