Career

As a PhD student at Murdoch University in Australia, Nyegaard lead a team of researchers in analyzing ocean sunfish DNA. While analyzing skin samples in 2013, she identified an undocumented species. She spent the next four years working with other researchers to identify and describe Mola tecta, or the hoodwinker sunfish, in 2017.[1][2] Nyegaard has continued to help identify specimens of M. tecta in New Zealand, Australia, Chile, South Africa, the Santa Barbara Channel, and the west coast of Canada.[1][3][4][5]

While working at the Auckland War Memorial Museum in New Zealand, Nyegaard led the effort to identify for the first time the larvae of Mola alexandrini.[6]
