Overview

Mary Agnes Joens assists the firm’s Chemical & Materials Technologies Practice, working with clients utilizing her research experience in fluid dynamics, soft matter physics, modeling of complex systems, and nanoparticle synthesis, characterization, and analysis. Her experience includes assisting with application drafting and prosecution as well as freedom-to-operate and patentability analyses.

Prior to joining Wolf Greenfield, Mary Agnes earned a PhD in Chemical Engineering from the Massachusetts Institute of Technology, where her research focused on non-Newtonian fluid dynamics. Her research projects included the development of frameworks for determining weakly nonlinear viscoelastic responses of complex fluids using novel microrheology techniques and modeling the motion of swimming microorganisms in complex fluids. Mary Agnes also served as a teaching assistant for an undergraduate fluid mechanics course.

As an undergraduate, Mary Agnes worked as a student researcher at the University of Massachusetts – Lowell, and has experience performing synthesis, characterization, and analysis of bimetallic alloy nanoparticles for use in both full-nanopowder and nano-composite solder pastes as well as electrochemical sensors. She has also worked as a fellow in the Particle-Based Functional Materials REU at the University of Pittsburgh, where she developed a Python-based model of ion and liquid transport in airway epithelial cells, which sought to provide mechanistic insight into cystic fibrosis pathophysiology and treatment. Mary Agnes was also a technology specialist summer intern at Wolf Greenfield before joining the firm full time.
