Plasmas have vary wide range of scientific and practical applications in our modern societies, including astrophysics, nanofabrication, nuclear fusion, sterilization of medical instruments, surface funtionalization, home lighting, etc. Plasmas are known to be very complex due to the interaction between several particle species, including positively and negatively charged ions, atoms, molecules, radicals, electrons, photons, and eventually nanoparticles, and to its high responsivity to self-induced and external electromagnetic fields, including laser fields. In particular, electrons, due to their small mass, generally have a complicated energy distribution but knowing it is essential to quantify most critical processes taking place in plasmas. For this reason, numerical modeling has always been an intrinsic and essential component of plasma physics. This research program aims at developing further several aspects of numerical plasma physics. The benefits of this research will include, for example, understanding (i) non-equilibrium plasma discharges, which exhibit distinctive properties compared to equilibrium plasmas and which can potentially be exploited in various applications, and (ii) the generation of nanoparticles in magnetized plasmas for applications in astrophysics and nuclear fusion. This research program will be a unique opportunity to train highly qualified personnel in this fascinating field of study.

等离子体在我们的现代社会中具有广泛的科学和实际应用，包括天体物理学，纳米纤维，核聚变，医疗仪器的灭菌，表面功能化，家庭照明等。由于几种粒子种类之间的相互作用，等离子体被认为是非常复杂的，包括带正电和带负电的离子，原子，分子，自由基，电子，光子，以及最终的纳米颗粒，以及其对自感和外部电磁场（包括激光场）的高响应性。特别是，电子由于质量小，通常具有复杂的能量分布，但知道量化等离子体中发生的大多数关键过程至关重要。因此，数值模拟一直是等离子体物理学的内在和重要组成部分。该研究计划旨在进一步发展数值等离子体物理学的几个方面。这项研究的好处将包括，例如，理解（i）非平衡等离子体放电，与平衡等离子体相比，它具有独特的特性，可以在各种应用中利用，以及（ii）在磁化等离子体中产生纳米粒子，用于天体物理学和核聚变。这项研究计划将是一个独特的机会，培养高素质的人才在这个迷人的研究领域。
