Research Summary

I am interested in developing mathematical and computational models for biological processes. I am currently working on building models for transport phenomena (diffusion and viscosity) in membranes. I am also working on modeling lipid membranes using mesoscale variables such as lipid tilt. I am co-advised by Prof. David Steigmann in the Mechanical Engineering department. During the course of my doctoral work with Prof. Ravi Iyengar at the Mount Sinai School of Medicine I focused developing models for understanding the mechanisms driving the relationship between cell shape and size during isotropic cell spreading. My current research is focused on developing mechanochemical models for endocytosis.
