Graduate Fellows and Postdoctoral Associates

Ugonna Ohiri

Ugonna graduated from The University of Maryland, Baltimore County with a B.S. in Computer Engineering. He came to Duke in 2013 and joined the Jokerst Group. His work focuses on using PN-junctions to design and fabricate directed particle self-assemblies. These assemblies, created from a variety of anisotropically ordered particles, may provide a breakthrough into the range of architectures that can be designed on the colloidal scale for an enhanced understanding and improved development of new materials with useful optical, electronic, chemical, and physical properties. 

Wyatt Shields

Project Affiliation: IRG 1

Wyatt is a graduate student in Prof. Gabriel Lopez's group in the biomedical engineering department. Wyatt’s research explores acoustic and magnetic methods for bulk and single cell manipulations in continuous flow devices as well as the programmed assembly of soft matter. He is interested in the synthesis of new materials from silicone elastomers with tunable acoustic and biochemical properties for rapid sensing and sorting assays. Wyatt is also actively engaged in the development of complex microparticles with patchy and non-spherical morphologies for assembly and field-controlled actuation.

Yiliang Lin

Yiliang is a Ph.D. at NC State University. He graduated from Zhejiang University (China) with a B.S. in Polymer Science and Engineering in 2013. Yiliang is currently co-advisored by Dr. Dickey and Dr. Genzer in Department of Chemical and Biomolecular Engineering. His research mainly focuses on synthesizing, modifying and patterning of gallium-based liquid metal nanoparticles for various applications such as soft electronics and drug delivery.  The goal is to explore a simple way to fabricate soft electronics utilizing the soft nature of liquid metals.

Yuankai Liu

Project Affiliation: Seed 5

Yuankai received his B.Eng. in Microelectronics from Zhejiang University in 2013.  After moving to Duke University, he joined Dr. Stiff-Roberts’s group in the Department of Electrical and Computer Engineering as a Ph.D. student and his research focuses on thin film deposited by resonant infrared matrix-assisted pulsed evaporation (RIR-MAPLE) and its applications in organic photovoltaic devices.

Yuxin Xie

Project Affiliation: IRG 2

Yuxin is a Ph.D. student at North Carolina State University. He graduated from Central South University (China) with a B.S. in Applied Physics. He came to North Carolina State University in 2013 and joined Dr. Yingling’s group. His work currently focuses on using molecular dynamics simulations studying LCST behavior of Poly (N-isopropylacrylamide). The goal of studying using these temperature-sensitive polymers is to have a better understanding of behavior of LCST and phase transition.
