DhitalChetan Dhital

Dr. Dhital earned his master’s degree in physics from Nepal and a PhD in physics from Boston College. He previously worked as a postdoctoral researcher at Oak Ridge National Laboratory.

Research interests: Study of novel electronic and magnetic phenomena in non-centrosymmetric intermetallic compounds, transition metal oxides, superconductors, heavy fermions etc. The research method includes both synthesis and characterization using magnetotransport, magnetization, magnetic force microscopy and neutron scattering techniques.

Award: GMAG graduate dissertation award for magnetism from American Physical Society (2014). Publications: more than 20 peer reviewed papers.


GuptaSudipta Gupta

Dr. Gupta received his master’s degree in physics from Indian Institute of Technology (IIT), Guwahati, India and a PhD in physical chemistry from the University of Muenster, Germany while working in Prof. Dieter Richter’s group at the Juelich Centre for Neutron Science (JCNS), Germany. Before coming to LSU he was a postdoctoral researcher at Oak Ridge National Laboratory (ORNL) in the Biology and Soft Matter Division.

Research Interests:

Constrained structure and dynamics in soft matter that includes complex fluids like synthetic polymers, biological macromolecules, colloids, glasses and polymer nano-composites. To understand the basic interactions governing their nanoscopic structures, which is manifested in their nanoscopic and macroscopic dynamics, in order to establish a structure-property relationship. Primary characterization methods include neutron scattering and spectroscopic techniques (SANS, NSE, Backscattering, TOF, etc.) Other techniques include different X-ray and light scattering, rheology and dielectric-spectroscopy. 

Fellowship: Fellow of International Helmholtz Research School of Biophysics and Soft Matter, Germany.  


KarnaSunil Karna

Dr. Karna received his master's degree in Physics from Tribhuvan University, Nepal and a PhD in Physics from National Central University, Taiwan. Before joining LSU in Feb 2017, he was a Research Scientist at the Center for Condensed Matter Sciences, National Taiwan University, Taiwan. His research covers systems that display novel physical properties, such as geometrically frustrated magnetism showing quantum spin behaviors, multiferroicity, Fe-based superconductivity, intermetallic compounds and ionic conducting materials. The strategies are to prepare polycrystalline and grow single crystals of them, and study them by X-ray diffraction, low temperature measurements, and neutron scattering techniques.

Zhenhua Ning

Dr. Ning’s research interests include electronic structure of solids using density functional theory based on either linear augmented-slater-type orbits or linearized augmented plane waves basis and KKR-Green’s function method with local density approximation (LDA) and meta-generalized gradient approximation (mGGA), simulating disordered alloys where coupling of charge, spin and lattice are important, calculating spectrum using either time-dependent density functional theory with mGGA or solving Bethe-Salpeter equation with GW correction. He earned his PhD in physics from University of Illinois at Urbana-Champaign. During this period, he participated in research on semiconductors at Academia Sinica in Taiwan. He earned his masters’ degrees in physics from both Peking University and University of Massachusetts Dartmouth.

Dr. Zhang began his work at LSU in April 2015. His research focuses on dielectric, ferroelectric, multiferroic materials, Fe-based superconductors and complex magnetic materials exhibiting spin glass, magnetocaloric effect, magnetoresistance, exchange bias effect, spin-orbit couplings, and strongly correlated electron behaviors. His most recent position was as a postdoctoral research associate in the Division of Materials Science & Engineering at Ames Laboratory and in the Department of Physics & Astronomy at Iowa State University. He earned his master’s and doctoral degrees at the Institute of Metal Research, International Centre for Materials Physics, at the Chinese Academy of Science, where he received the Shi Changxu Scholarship. During his studies he participated as an exchange PhD student in the Magnetic and Superconducting Materials Group at Leiden University in the Netherlands. He also served as a Marie Curie Fellow at the Centre National de la Recherche Scientifique in Caen, France and as a Newton International Fellow at the University of Glasgow, UK. He has first-authored 20 peer-reviewed papers.
