Research Interests

Increasing evidence supports the hypothesis that human exposure to environmental pollutants may have great impacts on human health. Specifically, it is now postulated that exposure to chemicals collectively named “obesogens” may contribute to the obesity epidemic and metabolic disease.  Further, it is recognised that chemicals may be carcinogenic and therefore contribute to the development of cancers in humans. 

Research Program

The research conducted in Dr. Atlas’ laboratory comprises two major projects. 

  • To develop in vitro models to investigate the effects of chemicals on fat cell formation, adipogenesis, and to investigate the effects of these chemicals on the phenotype of the mature fat cells. 
  • To investigate the carcinogenic effect of chemicals on the mammary gland in 3D models, using mammary epithelial cells.
  • Using 3D primary hepatocyte spheroid to investigate hepatic toxicity of chemicals.
