Chemistry teaching at University of Szeged has long‑standing and internationally acknowledged traditions and is closely linked to research activity, which has been practiced on high level for decades. On the first place the name Albert Szent-Györgyi has to be mentioned who received the Nobel Prize in 1937. At the same time and later he was succeeded by excellent scientists such as Győző Bruckner, Gábor Fodor, Árpád Gerecs, Árpád Kiss and Zoltán Szabó, members of the Academy. Although they left Szeged or died, there was no break in the requirements, either in teaching, or in research, as shown by the fact that currently four professors are members of the Hungarian Academy of Sciences.
Here we announce a postgraduate curriculum for students having graduate degree (MSc) in chemistry, chemical engineering, high school chemistry teaching or pharmacy for the following research fields.

Quantitative Structure-Activity Relationships (QSAR) and Quantitative Structure-Property Relationships (QSPR) are discussed in terms of multivariable descriptors. The use of Multiple Linear Regression (MLR) Analysis and Principal Component Regression Analysis will be critically assessed.

Structural bioinformatics
The aim of the course is to make acknowledgements on the tools for the characterization of protein structures, protein-small molecule (ligands/drug-like molecules), protein-protein and protein/small molecules with water molecules interactions. The tools are molecular mechanics methods modelling gas phase/solution media and molecular dynamics in implicit/explicit solvent models. Different methods applied in molecular dynamics will be discussed.The importance of the solution of Poisson-Boltzmann equation will be discussed at different pHs and ionic strengths. The methods of finding scaffolds (by shape and electrostatic complementary) by HTS (High-Throughput-Screening) or fragment types prediction of effective design of molecules will be reported.

Introduction to the quantum theory of atoms and molecules
After a short overview of the quantum mechanical background, the most popular methods of ab initio quantum chemistry are discussed such as Hartree-Fock and electron correlation methods (many-body perturbation theory, configuration interaction and coupled cluster methods) as well as the basics of the density functional theory.

Quantum chemistry of periodic polymers
Using the formalism of the solid state physics, generalization of the fundamental quantum chemical methods (Hartree-Fock, correlation methods and density functional theory) is discussed. Some representative applications of the theory are also presented like structural and electronic properties of conducting and semiconducting polymers, biopolymers and nanotubes.

Density Functional Theory
Following a brief mathematical (functional derivation) and historical (Thomas-Fermi model) introduction of the Density Functional Theory (DFT), the basic theorems (Hohenberg-Kohn I, II) and calculation scene (Kohn-Sham equation) are proved. The derivation of the simplest exchange functional form (X-alpha) is discussed in detail, and the improving methods (gradient correction) as the hybrid and orbital dependent functionals are also analyzed. Finally, the extends of the original theorems (excited states theorems, time depending DFT) are also presented

Introduction to theoretical chemistry
The goal of the two-semester course is to provide a strict theoretical (mathematical) background to learn advanced quantum mechanics, quantum chemistry, computational chemistry and molecular modeling. By the end of the course it is expected from students to have almost all the theoretical tools they need in studying chemistry at the highest level of theory.

Quantum organic chemistry
Application of modern quantum chemistry to organic molecules to elucidate their structures and other physical and chemical properties including electrostatic, magnetic, spectroscopic and thermochemical properties. By the end of the course, the students can start real scientific projects in the field in question.

Quantum-algebraic-combinatoric study of molecules
The joint application of quantum chemistry, abstract algebra and applied combinatorics to enumerate the various isomers (structural, conformational, etc.) of basic molecules. Simple QSPR and QSAR methods are also considered for modeling purposes and compared to more sophisticated quantum chemical models.
