Title:  Postdoctoral Associate- Metabolomics and Mass Spectrometry

Division:  Pediatrics
Schedule:  Monday - Friday, 8:00 A.M. - 5:00 P.M.
Work Location:  Houston, TX
Salary Range:  $54,840 - $57,852
FLSA Status:  Exempt
Requisition ID:  13562


A Postdoctoral Associate position is available in Dr. Xia Gao’s laboratory in the Department of Pediatrics at Baylor College of Medicine. We are interested in the interactions of nutrition, metabolism, and the development and treatment of metabolic diseases such as obesity and cancer. The goal is to identify nutritional interventions and metabolic pathways for prevention and treatment of metabolic diseases.


We employ untargeted and targeted metabolomic analysis and isotope tracing studies using newly vested in-house Thermo Exploris 480 LC/MS instrument. Along with this powerful analytical tool, we use various in vivo mouse models and in vitro models to define the role of nutritional input and the underlying mechanisms in disease development and control. For instance, we have recently (Nature, 2019) employed metabolomics approaches to show that dietary methionine restriction is an effective and feasible dietary intervention in healthy humans and mice to alter circulating metabolism without overt side effect. Dietary methionine restriction has shown promising in various mouse cancer models alone or in combination with chemotherapy or radiotherapy. 

Job Duties

  • Performs research under the general direction of the Principal Investigator.
  • Plans, directs, and conducts metabolomics and metabolic flux studies, and others as they emerge.
  • Collects and analyzes data, and prepare slides, figures and manuscripts for publications.
  • Develops new research directions.
  • Trains new lab members, junior lab members, and students.

Minimum Qualifications

  • MD or Ph.D. in Basic Science, Health Science, or a related field.
  • No experience required.

Preferred Qualifications

  • Three years of relevant experience typically as a Research Assistant, Research Technician or PhD. 
  • Ph.Ds. interested in our research and with prior experience or expertise in analytical chemistry and metabolism are encouraged to apply.
