I work with the bioprinting team and am interested in scaling up our kidney organoid models to print scalable, vascularized tissues. I also aim to develop improved proximal tubule models for disease modeling and drug screening.
Bok Yeop Ahn received his PhD in Chemical Engineering from Korea University in 2006 and joined the Lewis research group in the University of Illinois at Urbana-Champaign (UIUC) as a postdoctoral researcher. During his Ph.D., he worked for the Korea Research Institute of Chemical Technology (KRICT) in the Advanced Materials Division and focused his researches on the transition metal oxide nanoparticles, sol-gel coatings, and alkyl-modified silica core/shell microcapsules. He moved to Harvard University in 2013 and currently holds the title of Senior Research Scientist in the Lewis Research Group through the Wyss Institute and the School of Engineering and Applied Sciences (SEAS). He focuses his efforts on the development of functional inks and direct-write assembly of printed electronics, 3D microbatteries, and 3D bio-architectures.
Boston University, Biomedical Engineering, BS NSF Graduate Research Fellow
I am interested in the relationship between structure and function at the micron-scale in living tissues. My research investigates 3D printed biodegradable elastomeric grafts that can be remodeled into mechanically anisotropic tissues in vitro and in vivo. Currently, I am working with the Massachusetts Eye and Ear Infirmary to design tympanic membrane grafts with tailored motion patterns in response to acoustic stimuli. Eventually, we hope that this technology will improve hearing outcomes following tympanoplasty surgery.
During his PhD, Alex investigated processes for fabricating intrinsically stretchable transistors and pressure sensors for biomimetic and neuromorphic electronics. In the Lewis Lab, Alex is developing printed electronics for bio-interfacing applications.
Helen got a Ph.D from Univ.of Illinois at Urbana-Champaign in materials science engineering division focused on electronic materials processing and characterization. Helen worked for various industrial companies like IBM for hard disk drive development, Cypress semiconductor for non-volatile memory development (MRAM), PerkinElmer Bio for x-ray imaging panel development and ASM for next generation 7nm CMOS logic chip development.
Emily Davidson received her PhD in Chemical Engineering working with Professor Rachel Segalman. There, she studied the impact of confinement within block copolymer microdomains on the crystallization of conjugated polymers, and examined the role of controlled polymer stiffness on the self-assembly of sequence-controlled block copolymers. In the Lewis Lab, Emily's research focuses on 3-D printing block copolymer and shape-memory polymers to control the local anisotropic optical and mechanical properties in 3-D printed structures.
Zoey received his PhD in soft matter physics at the University of Pennsylvania and then moved to the Max Planck Institute for Intelligent Systems where he developed electrically driven liquid crystal elastomer actuators. In the Clarke and Lewis groups, his research focuses on materials and device design to improve performance and fabrication of electrically driven soft actuators. Using materials and methods such as liquid crystal elastomers and 3D printing, he is creating new actuation mechanisms for soft robotics with an eye on the fundamental physics to better understand these systems.
Swiss Federal Institute of Technology, PhD Society in Science - Branco Weiss Fellow
The inherent limits of the existing printing technologies strongly restrict the range of possible inks (i.e.materials) that can be dispensed, hence the potential applications of such technologies. Could we do better? As a Branco Weiss fellow, I will investigate a new concept of printing mechanism based on ultrasound. By using acoustic forces any ink could be potentially printed on any substrate.
During his PhD, Edward synthesized and characterized small-molecule liquid crystals (LCs), studying the structure-property relationships for nanophase segregating groups in polar LC phases. In the Lewis Lab, Edward is working on designing LC elastomer based actuators for applications in soft robotics.
