My contributions to this paper include simulations of block copolymer directed self-assembly in the "hole-shrink" process, demonstrating that our coarse-grained simulations predict the same morphologies observed through direct imaging of 3D structures from experiments.

This paper uses the string method to investigate the mechanism of the formation of through film cylindrical morphologies in cylindrical confinements during block copolymer directed self-assembly. We find that the assembly process most critically depends on the interaction between the polymer and the confinement sidewall.

My contributions to this paper were using Monte Carlo simulations of block copolymer self-assembly to build phase diagrams of block copolymers confined in elliptical templates. I helped demonstrate that there is a certain window of concentration of homopolymers that stabilize well-separated double cylinder structures in such confinements. My simulations also helped verify that the homopolymer preferentially segregates to certain regions of the film, lending credence to the experimental hypothesis of the mechanism of the homopolymer stabilization of a doublet structure.

In this talk I introduced preliminary results from my 2018 Macromolecules paper on the mechanisms of directed self-assembly during the hole shrink process.
In this talk I introduced preliminary results for a forthcoming paper using molecular simulations to study the unique defects seen experimentally in https://pubs.acs.org/doi/abs/10.1021/acs.nanolett.7b03881 and https://pubs.acs.org/doi/abs/10.1021/acsami.8b05247. Full details will be available in the draft coming soon.
In this talk I introduced preliminary results using molecular simulations to study the phase behavior of the bricks-and-mortar phase formed from a nonlinear block copolymers architecture (prior results can be found in https://pubs.acs.org/doi/abs/10.1021/acs.macromol.5b01210 and https://pubs.acs.org/doi/abs/10.1021/acs.macromol.7b01106); the primary innovation of our work is to use three-dimensional particle-based simulations to probe the phase diagram and dynamic properties of the mesophase.
In this talk I elaborated on preliminary results first shown in the prior talk at APS, on using molecular simulations to study the phase behavior of the bricks-and-mortar phase formed from a nonlinear block copolymer architecture; this talk had a primary focus on calculations of mechanical properties (viscosity, dynamic modulus, and Young’s modulus especially).
In this talk I followed up on my prior talk at AICHE on using molecular simulations to study the phase behavior of the bricks-and-mortar phase formed from a nonlinear block copolymer architecture; this talk had a primary focus on calculations of mechanical properties (viscosity, dynamic modulus, and Young’s modulus especially), with updates to my calculations where appropriate.

In this course I was responsible for leading recitations, grading homeworks, and collaborating on writing exams.
Graduate course, University of Chicago, Institute for Molecular Engineering, 2017
In this course I had a slightly expanded role from the undergraduate counterpart in 2017. In addition to grading homeworks, collaborating on writing exams, and leading recitations, I also helped design assignments and filled in for occasional lectures.
Undergraduate course, University of Chicago, Institute for Molecular Engineering, 2018
In this course I shared some of the responsibilities I had held the previous year (collaborating on writing exams, grading homework, holding office hours) while also adding the responsibilities of designing a short series of lectures focusing on thermodynamic cycles and processes, which I also delivered. Additionally, I helped manage the course’s graduate teaching assistant.
