Grigor Nika

Grigor Nika is an Assistant Professor of Mathematics at Karlstad University (SE) since 2022. He holds a Ph.D. in Mathematics from Worcester Polytechnic Institute (USA, 2016), with prior postdoctoral positions at WIAS Berlin (DE), WPI (USA), and CNRS/Ecole Polytechnique (FR). His research focuses on theoretical and computational aspects of materials science, including multiscale modeling, homogenization techniques, and electromechanical systems. He specializes in developing effective medium theories for heterogeneous materials, analyzing chiral effects in elastic media, and simulating semiconductor device thermodynamics.

Key research areas include:

• Non-local continuum mechanics frameworks
• Magnetorheological fluid dynamics
• Thermal flux modeling at small scales
• 3D-printed metamaterial design
• Biomaterial biomechanics

Notable contributions include pioneering work on second-gradient elasticity with chirality effects and innovative topology optimization approaches for auxetic materials. His recent articles explore advanced numerical schemes for phase-field models and data-driven parameter estimation for stochastic systems.

Collaborations involve interdisciplinary teams from mathematics, engineering, and materials science. He has designed experimental validation protocols for micro-architected polymers and contributed to flood exposure modeling studies in Sweden. Current research emphasizes energy systems applications through mathematical modeling and simulation strategies.
