University of Mississippi senior Megan McKissick presented her research on the theoretical characterization of the rotational and vibrational behavior of various molecules potentially present in space that may be related to the interstellar origins of life. She was one of six undergraduates selected to present at the American Chemical Society Presidential Symposium.

Why it matters

McKissick's research can help scientists find new cosmic molecules that may be related to how life began. Similar carbon-based molecules containing oxygen and nitrogen atoms have been detected near molecular clouds in space and may react on interstellar ice and dust to form amino acids or other biomolecules essential for life processes.

The details

McKissick, a chemistry major specializing in chemical physics, focused her presentation on the two molecules 1,2-diiminoethane and 2-iminoacetaldehyde, which may be related to the interstellar origins of life. Her research can help clarify the molecular origins of life, as these types of molecules can then be transported to planets by meteorites.

  • Earlier this week, McKissick presented her findings at the American Chemical Society Presidential Symposium on March 23.
  • University chapters of the American Chemical Society nominated more than 135 students from across the nation to present at the conference in Atlanta.

What they’re saying

“My research focuses on the theoretical characterization of the rotational and vibrational behavior of various molecules potentially present in space.”

— Megan McKissick, University of Mississippi Senior

“Undergraduate research is the best way for our undergraduate majors to really start to understand what chemistry research really means. Students are able to contribute to real-world projects that benefit society.”

— Nathan Hammer, Professor of Chemistry and Biochemistry, University of Mississippi

“Megan actually was a little overwhelmed on her first day of research with me, but she didn't let that stop her. And now here she is: she has already been author on three publications as an undergraduate student and should have at least two more publications as a result of her work.”

— Ryan Fortenberry, Associate Professor of Chemistry and Biochemistry, University of Mississippi

The takeaway

McKissick's research on potential cosmic molecules related to the origins of life highlights the valuable role of undergraduate students in advancing scientific knowledge and making real-world contributions, even before completing their degrees.
