Research Interests

My research program aims to develop new technologies to interrogate and manipulate biological systems at the scale of individual cells. Our work leverages advances in materials, fabrication, instrumentation, and computation across multiple domains and length scales. Current research activities include the following areas:

  • Microfluidics
  • Cell Sorting
  • Cell Biomechanics
  • Single cell sequencing
  • Single cell secretion
  • Image cytometry
  • Machine Learning
  • Laboratory automation
