Laura Burns
R&D Director, Omega Yeast
Brewing isn’t a typical career path for research scientists with doctorate degrees, but for Laura Burns it was a practical way to apply academic learning in a creative environment. After finishing her doctorate, she worked in brewhouses from Tennessee to Chicago before landing at Omega Yeast, where she’s assumed the title of director of research and development. There, she’s helped develop new yeast products to solve problems for brewers, and she’s worked diligently to understand why and how yeast create certain flavors and textures in beer.

What students say
Very well presented, there are so many exciting advances taking place in the brewing scene and the way yeast, hops, and malt all interact with one another is kind of mind blowing. Lots of food for thought with this class.
This has been the best presentation of yeast and thiols. Great Job!
An awesome and in-depth explanation on yeast and how it’s use in beer is changing the game. Mandatory info for hazy beer makers
