So excited to introduce myself to this community and announce I'm officially on the faculty job market this year! Please don't hesitate to reach out if you are interested in connecting about polymer science, drug delivery, biomaterials, immunoengineering, and global health!
My research vision is to mechanistically define how polymer structure impacts biophysical phenomena, such as interfacial protein interactions and immune responses, to engineer accessible drug delivery technologies
