A postdoctoral investigator position is available in the laboratory of Dr. Esther Guzmán in the Marine Biomedical and Biotechnology Research Program at Harbor Branch Oceanographic Institute at Florida Atlantic University in Fort Pierce, FL. This is a 1-year grant-funded position with the possibility of renewal for a second year based upon performance. The research that will be conducted will fulfill the aims in a grant supported by the Florida Department of Health to identify marine natural products that induce cytotoxicity in triple negative breast cancer cells grown as spheroids.

With over 30,000 students from all 50 states and over 180 countries, 21 intercollegiate teams, 180 plus degree programs, and an administration that thrives on discovery and excellence, FAU is pushing the boundaries of higher education. Florida Atlantic's faculty and staff are trailblazers and innovators with a passion for finding creative solutions while advancing science, art, and technology in all disciplines. Our work environment is a hub of cultures from across the nation and the world, making FAU a place where collaboration flourishes.

Summary of Responsibilities Include:

  • Isolating protein for functional proteomic analysis for selected compounds and analyzing the data provided by the Functional Proteomics Reverse Phase Protein Array Core Lab performing the analysis.
  • Preparing samples to conduct L1000 gene expression analysis and analyzing resulting data provided by the company that performs this analysis.
  • Using databases such as LINCS and Connectivity Map from the Broad Institute and STRING from EMBL to analyze the proteomic and genomic data.
  • Testing selected compounds on heterospheroids of triple negative breast cancer cells with fibroblasts or macrophages to address tumor-stroma interactions in a high content imager.
  • Conducting 3D tumor spheroid invasion assays to determine if selected compounds affect metastatic potential.
  • Validating proteomic/genomic results using siRNA, functional assays or flow cytometry and/or western blotting.
  • Maintain a high level of productivity in the laboratory setting.
  • Proactively seek out new information in the literature and incorporate this information into the individual project as well as the overall program.
  • Prepare manuscripts on research findings for submission to high impact peer-reviewed journals and present work at scientific conferences.
  • Demonstrate a high degree of responsibility in maintaining scientific standards and safe laboratory practices for self and reporting staff if any.
  • Supervise one or more summer interns.
  • Maintain accurate and current records of research and/or project related activities.
