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.

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.


Ahmad Us SaleheenAhmad Us Saleheen

Dr. Us Saleheen received his PhD in Physics from Louisiana State University. He is an experimental condensed matter physicist, specializing in materials synthesis, characterization, and optimization. In his doctoral research at LSU, he investigated the magnetic properties, thermodynamic properties, magneto- and barocaloric properties, and complex phase transitions (structural and magnetic) in a wide variety of material systems. 




Damien Tristant

Damien Tristant

Dr. Tristant earned his PhD in Nanophysics from Paul Sabatier University in Toulouse (France) in 2016, under the supervision of Dr. Iann Gerber (Density Functional Theory) and Dr. Pascal Puech (Raman Spectroscopy). He previously worked as a postdoctoral research associate at Rensselaer Polytechnic Institute. His main research experience uses computation to examine the thermodynamic, electronic, vibrational, optic, magnetic and transport properties of materials at the atomic level. 



Yu Li

Yu Li

Yu Li received his bachelor's degree in Applied Physics from Shandong University and master's degree in Physics from Renmin University of China. He studied neutron scattering with Dr. Pengcheng Dai at the University of Tennessee, Knoxville, and obtained his PhD in Physics after moving to Rice University in Houston, TX. He has broad interests in correlated electronic material in which various fascinating quantum emergent phenomenon have been observed and advanced theoretical concepts tested.  

His past research focused on fundamental interactions between charge, spin, orbital and lattice in iron-based superconductors, such as Mott physics, Hund's coupling, spin-orbital coupling, spin-lattice coupling, and the resultant novel quantum phases, for instance, unconventional superconductivity and electronic/spin nematicity. His current interests include searching for topological objects such as skyrmions  in various non-centrosymmetric magnetic material and studying their dynamic behaviors.
