Applications of Molecular Modeling to Study Interfacial Phenomena II

Recent advancements in nanoscience and engineering have focused on fabricating multifunctional and adaptive structures that mimic the behaviors of living systems. However, there still exists an enormous performance gap between synthetic and natural materials due to challenges in controlling morphology and properties (i.e., stiffness, conductivity, opacity, etc.) across multiple length scales. Nanoscale tunability enables the fabrication of dynamic materials that exhibit programmed and decentralized responses similar to those found in nature. My Ph.D. work and current research aim to address this multiscale challenge by fabricating functional structures from soft, polymeric materials with locally tunable morphology and physicochemical properties for electrocatalysis, mechanobiology, and soft robotics.
In this poster, I present electrochemical polymer pen lithography (ePPL), a novel method for performing electrochemical reactions at the nanoscale to deposit metallic structures over large areas for electrocatalysis. I also discuss how the same lithography platform can be employed to perform localized photochemical reactions to fabricate cellular scaffolds with features on the sub-cellular and microscale, recapitulating the complex topography and stiffness of the natural extracellular matrix. My postdoctoral work is highlighted, which focuses on 3D printing of architected poly(ionic liquid) composites that feature spatially programmed anisotropic mechanical and electrical properties for ionotronic applications. I will also introduce soft actuators printed via extrusion-based printing methods where controlled alignment of small particles affects the shape morphing behaviors observed on a bulk, centimeter scale.
Extending beyond controlling materials properties across multiple length scales, I aim to develop electroactive reconfigurable material systems and processing methods to address global challenges in climate, energy, and sustainability. I plan to utilize the reversibility in the redox process to modulate the chemical, mechanical, optical, and electrical properties of polymer structures. Building on my ePPL work, I will create high-throughput, lithographic-based platforms for the rapid in situ synthesis, characterization, and screening of electroactive polymers to accelerate a comprehensive understanding of the polymeric systems. Through the integration of polymer chemistry, materials screening, and multiscale processing, I will take a convergent, interdisciplinary approach to engineering high-performance sustainable materials. I envision building an interdisciplinary lab dedicated to promoting a circular economy and a self-sustainable society.
Teaching Interests
My teaching philosophy is rooted in the belief that learning is not merely a passive acquisition of knowledge, but an intrinsic, dynamic, and continuous process akin to the very act of eating. Just as our bodies convert food into energy, true learning goes beyond information intake and involves a transformative process of consumption, digestion, absorption, and conversion to transform acquired knowledge into practical solutions. I aim to promote this dynamic, transformative, and holistic learning to produce next-generation chemical engineers and polymer scientists who drive innovations that benefit the world. My teaching will focus on four main strategies: (i) motivating studentsâ interests in science and engineering, (ii) fostering an interactive and inclusive atmosphere, (iii) integrating state-of-the-art technologies, and (iv) providing personalized and equitable mentoring.
Methodologically, I am well-equipped to teach existing courses related to introductory chemistry (general chemistry, organic chemistry, electrochemistry, and thermodynamics) and polymer chemistry (synthesis and characterization). My interdisciplinary training from Northwestern University has also prepared me to build specialized courses based on my research, including soft materials, nanoscience, nanotechnologies, microfabrication, and 3d printing. For example, I propose to build a course aimed at first- or second-year graduate students and advanced undergraduates titled âFrom nanopatterning to 3D printing: engineering polymer for functional systems.â This course will explore the fundamental principles of polymer patterning and printing methods, properties of compatible polymers, and structure-property relationships of printed structures. A key learning module will involve students fabricating a utilitarian product with CAD software and through a conventional 3D printer, employing materials learned in class. This module will allow students to contextualize their learning tangibly through hands-on experiences.
