CHADRON – Chadron State College students and faculty attended the Nebraska Academy of Sciences Conference April 21-23 in Lincoln. The students were Isioma Akwanamnye of Lagos, Nigeria, Corey Griffin of Omaha, Riley Hill of Greybull, Wyo., Abigail Klammer of Juniata, Neb., Spencer Knuth of Holdrege, Neb., Joshua Kruse of Gurley, Neb., Jared Nelson of Gordon, Neb., Thea Rosberg of Wausa, Neb., and Emmanuella Tchona of Republic of Benin. The faculty included Dr. Ann Buchmann, Dr. Mary Keithly, Dr. Jeffrey Kiiskila, and Dr. Mike Leite.

Other students who presented virtually included Beau Jersild and Robert Logan Tiensvold of Chadron. Tiensvold won the Nebraska Geological Society prize for best undergraduate paper in the Earth Sciences.

Leite said he was honored to see the student presentations.

“I am proud to have played a part in the education of these talented young scientists,” Leite said.

Klammer and Rosberg are NASA fellows, and Akwanamnye, Kruse, and Tchona are IDeA Networks of Biomedical Research Excellence (INBRE) students. INBRE is a statewide grant program that funds Nebraska undergraduates’ research for two years. Akwanamnye, a graduating INBRE student, has been accepted at Case Western where she will be doing graduate-level cancer research.

Keithly said the students did an amazing job presenting their research.

“They presented high-quality research and connected with fellow scientists from other Nebraska higher education institutions. I was very proud of everyone that participated both in-person and online,” Keithly said.

Recent CSC graduates who conducted research and helped write presentations but did not travel to Lincoln included Lelisse Umeta, Feven Hailemariam, Alisha Huynh, and Joseph Keating.

Faculty who contributed to or supervised research, but did not attend the conference include Dr. Tim Keith and Dr. Tawny Tibbits.
