Dr. Heinrich Gugger, formerly president of Syngenta Crop Protection, is the new chief executive officer at Paradigm Genetics.

The announcement was made early today.

Gugger replaces Dr. John Hamer, who had served as interim CEO following the firing earlier this year of company founder and CEO John Ryals. Paradigm said Hamer will remain with the company as its chief science officer.

Gugger was president of Syngenta when it was merged with Novartis Crop Protection and Zeneca Agrochemicals. He also worked earlier in his career for Novartis and is a member of the board of the North Carolina Biotechnology Institute.

Ryals was fired by Paradigm on Feb. 26 in a dispute with the board over the direction of the company. He resigned his seat on the company’s board in May.

Paradigm (Nasdaq: PDGM) stock closed at $1.25 a share on Wednesday, up 2 cents. Just a year ago the stock traded at $8 a share, and it was selling at $6 a share in December. The company has laid off much of its workforce in recent months and also went through a reorganization.
