Research Interests  

  • Cell therapy and regenerative medicine
  • Measurement assurance strategies
  • Cell counting and cell viability measurements
  • Bio-mineralization and osteogenic differentiation measurements
  • Bone marrow stromal cell characterization
  • Cell-material interactions
  • Cell shape metrology and machine learning strategies
  • Biomimetic polymer synthesis & characterization

 Cell Characterization

Left: Confocal microscopy image of NIH 3T3 E1 mouse osteoblastic cells after 21 days of culture stained for nuclei (blue, DAPI), actin cytoskeleton (yellow, phalloidin) and mineral (red, calcein blue). Middle: Confocal microscopy image of a human marrow stromal cell (hMSC) in a nanofiber scaffold, outlined for morphology analysis (red, actin cytoskeleton (phalloidin), green, computer generated outline). Right: NIH 3T3 fibroblasts in a hemocytometer counting chamber. Cell counting is a fundamental measurement for the biosciences and efforts are underway to improve confidence in cell counting.
