Postdoc: volatiles mass spectrometry and machine learning

Please apply by November 10, 2019

The USDA Agricultural Research Service, Center for Medical, Agricultural, and Veterinary Entomology (CMAVE) has an opening for a postdoctoral research associate. The project primarily involves developing volatiles-based mass spectrometry and machine learning technology to dramatically improve animal welfare in the egg industry.

The Challenge

About 700 million chicks are hatched annually in the US egg industry. Half of those are male and they are culled the day they hatch because they lack economic value. We are developing a method to determine the sex of the egg when it is laid. Our novel approach uses rapid volatile compound mass spectrometry and machine learning. This will allow the male eggs to be diverted and used for food products before the chick develops the ability to sense pain. Early sex identification also reduces industry costs by reducing the need for egg incubators and labor. The postdoc in this position will build off the existing work and intellectual property of the group to quickly create a viable commercial prototype in 18 to 24 months.

Desired skills

  • good experience in any field of mass spectrometry.
  • Additional knowledge in analytical chemistry, chemical ecology, poultry, or statistics is a plus.
  • An ideal candidate will also have a collaborative, inventive and entrepreneurial spirit, a problem-solving mentality, and an interest in gaining valuable skills in machine learning.

I recognize that each person has a unique mix of experience and individual strengths and I encourage any applicant with a strong record of research productivity and relevant experience to apply, even if your mix of skills is different than what is listed above.
