Graduate Fellows and Postdoctoral Associates

Pandiyarajan, Chinnayan Kannan (aka. C. K. Pandiyarajan)

Project Affiliation: IRG 2

Dr. C. K. Pandiyarajan holds a Postdoctoral Research Associate position at the Department of Chemical and Biomolecular Engineering, NC State University with Prof. Jan Genzer. He completed his doctoral degree (Dr. rer. nat. with ‘magna cum laude’ in April 2013) on the interaction of blood proteins and platelets with surface-attached hydrogels under the supervision of Prof. Jürgen Rühe, Department of Microsystems and Engineering (IMTEK), Albert-Ludwigs-Universität Freiburg, Germany. As a postdoc, he developed a versatile synthetic methodology to generate surface-anchored orthogonal gradient poly(N-alkylacrylamide) networks exhibiting continuous variation in crosslink density and modulus in two opposite directions. At present, he is working on the development of a random crosslinking model for surface-anchored networks in collaboration with Prof. Michael Rubinstein from University of North Carolina, Chapel Hill, NC.

His research goals are centered on the development of functional biomaterials/coatings for tissue engineering (TE), artificial implants, and medical device applications. He is also interested in understanding the physiochemical properties that govern the anti-biofouling character of polymer networks and brushes (mechanistic view on how proteins/cells arrive and attach onto the surface of a foreign material). At present, he is actively searching for a tenure-track faculty position in the biomaterials or closely related fields. LinkedIn.

Qing Tu

Project Affiliation: IRG 2

Qing has developed unique capabilities to map the mechanical properties of polymeric thin-films and 2-D materials, using acoustic resonance AFM. Qing is in charge of the MRSEC scanning probe instrumentation, and in this capacity he has contributed to MRSEC research, e.g., by working on “Peptide-based Functional Film: Enhanced Adsorption of Elastin-like Polypeptide Block Copolymer on Silica”, and he has had increasing involvement with the SPM-related activities of Seed 9, where he started to map out the mechanical properties and the contact potential differences of crystalline, hybrid organic-inorganic boundaries.

Qixin Shen

Qixin received his B.S. in Physcis from Peking University in Physcis department. . He joined Professor Maiken H. Mikkelsen's group and is a PhD candidate in the Department of Physics at Duke University. His research focuses on light-matter interactions in semiconductor nanostructures and at interfaces. He currently works on gold gratings project to try to find the connection between the strength of nonlinear signal and surface roughness of gold film. He is also interested in researching NV center in diamond.

Renpeng Gu

Project Affiliation: IRG 2

Renpeng Gu is currently a third year Ph.D. student in Dr. Stefan Zauscher’s lab at Mechanical Engineering and Materials Science Department. His research interests include the design, synthesis and characterization of different architectures of stimulus-responsive bioinspired materials. Renpeng has synthesized photo-responsive polynucleotide micelles via copper-free click chemistry. Currently, his main research project is to synthesize triblock DNA copolymers via DNA hybridization and TdT enzymatic polymerization, and study the self-assembly of this material.

Ryan Maloney

Project Affiliation: IRG 1

Ryan Maloney graduated from the University of Illinois at Urbana-Champaign with a degree in Chemical Engineering in 2008. He came to NCSU in 2014 and joined the Hall group. His work focuses on discontinuous molecular dynamic simulations of colloids.

Samuel Alvarez

Project Affiliation: IRG 1

Samuel is currently working in Professor Benjamin Wiley’s lab in the chemistry department. He received his BA in chemistry from Connecticut College in 2012. His research focuses on the role of light on copper nanowires growth and using light to photomap these nanowires into certain patterns. He is also studying the mechanism of how branching occurs in some of these nanowires.

Scott Lindauer

Scott graduated from Clemson University with a degree in Physics. He came to NCSU in 2013 and joined Dr. Karen Daniels' group. His work focuses on microfluidic flow of nano- to micron-sized particles of differing shapes. He considers the dynamics of pile formation and hydrodynamic flow at nano and micron levels.

Stefan Roberts

Project Affiliation: IRG 2

Stefan is a Ph.D. student in Dr. Ashutosh Chilkoti’s lab in the Biomedical Engineering department at Duke University. He received a B.S. in BME from Washington University. His research is presently focused on engineering stimulus responsive behavior into therapeutically active peptide sequences allowing incorporation of both biological activity and stimuli-responsiveness into a single, seamless peptide polymer.

Sumeet Mishra

Project Affiliation: IRG 1

Sumeet is a Ph.D. student in Joe Tracy's Magnetic and Metallic Nanoparticle Research Group. His work is focused on dispersing multifunctional nanoparticles in different polymers and assemble them to obtain directional preference for their properties. This allows for a selective response which could be a shape change or directional actuation.

Ting Ge

Project Affiliation: IRG 2

Dr. Ge is a postdoctoral research associate in Prof. Michael Rubinstein's group at UNC-Chapel Hill. He performs computational and theoretical studies in polymer and soft matter physics. Within MRSEC, his research aims to understand the self-assembly behavior of genetically engineered polypeptide copolymers. Before moving to the research triangle, Ting obtained his Ph.D. from the Department of Physics & Astronomy at Johns Hopkins University.
