Among the most important and significant research schools within the University we can name the following:
1. A school of Prof.Yuri G.Kabaldin,
Doctor of Engineering, Full Member of Russian Academy of Sciences.
Its main area of focus: Cutting tools' performance enhancement/monitoring at operation in automated manufacturing environment.
The novelty and significance of this school lies in the fact that its methods have been founded upon the structural energy approaches and upon the synergetic approach to the problem of materials' wear and destruction, which Prof.Y.G.Kabaldin has been developing over the recent years.
This approach allows for comprehensively taking into account all the variety of processes and phenomena that occur during machining operations, which helps more reliably and with better results solve the problems of new-tool materials development and of how to make them stronger.
For the purpose of improved operational reliability and performance of cutting tools, a number of methods for integrated-effect treatment of cutting tool flanks have been developed and tested in lab and in a production environment, which includes thermoplastic strengthening and multilayer wear-resistant coating; also methods have been suggested for performance enhancement of ceramic inserts and superhard materials.
Within this scientific-engineering framework, our researchers have performed many commercial contracts that have already totalled 1 mln roubles in price, and completed one of the tasks that are included into the task-plan of the Ministry of Education of Russia.

With time, this field of scientific investigation has split into three independent research areas::
Within this research school led by Prof. N.A.Taranukha, one doctoral degree and five PhD degrees in Engineering and one PhD degree in Physics&Mmathematics have been obtained, and several MA level theses have been defended. Currently, one doctoral and two PhD candidates have been nearly 100% through with their respective theses. One more doctoral candidate and three PhD ones are working on their dissertations.
Prof. N.A.Taranukha is a member of two doctoral dissertation boards.
- modular elements method and behaviour of shells (G.S.Leizerovitch, O.V.Zhurbin, N.G.Tchudinova, I.V.Kamenskich);

3. A research school of Prof. Victor M.Kozin
Doctor of Engineering.
Main area of focus: Integrated study of hydromechanics and ship theory problems.
To effectively solve the problems of and achieve tasks in the domain of hydromechanics and ship theory, the Department of Shipbuilding of the University has been working for 20 years to develop and further improve the only test facility of this kind in the Far East of Russia – a Model Basin for ship model tests. This unique research engineering tool has made it possible for a team of researchers and engineers led by Prof. V.M.Kozin to carry out – for the first time in the Far East – studies in the area of innovative reverberation-based ice breaking technology with the help of air-cushioned ships, which can help make sea navigation in the Northern waters longer; accordingly a wide range of theoretical studies have been undertaken to prove that such ice-breakers can be designed and constructed.
Various studies based on the Model Basin data are complemented by researches in the area of design engineering of new types of ships, like transport vessels for bulky and heavy cargo, barge carriers, compound ships (N.A.Mytnik, PhD in Engineering, Associate Professor), innovative dynamically supported crafts (V.T.Shepel, PhD in Engineering, Associate Professor), open container carriers (senior lecturer A.D.Burmensky) – all of the above being a sizable contribution into the theory of shipbuilding.

4. A research school of Prof. Alexey I.Yevstigneev
Doctor of Engineering, Provost for Research.
Main area of focus: physical and chemical properties of shell molding; new composite ceramic materials made from domestic raw materials and used for the production of moulds for hot investment casting.
On the basis of research done in this area so far, a research school led by Prof. A.I.Yevstigneev has formed itself and today bears the name of: "Development and improvement of special types of molding". A foundation for it was provided by works completed by Prof.A.I.Yevstigneev in the city of Nizhny Novgorod under the leadership of Prof.G.I.Timofeev.
This research school is characterized by its focus on practical aspects and reliance upon local raw materials and resources. Several region's plants and factories have already entered into commercial contracts with the University willing to use these new developments in their processes.

5. A research school of Prof. Ahmet A.Husainov,
Doctor in Physics and Mathematics.
Main area of focus: homology theory and theory of cohomology of small categories. Homology- and cohomology-related subdivisions of algebra, topology, analysis, discrete maths and computing.
6. A scientific school led by Prof. Sergey I.Feoktistov
Doctor of Engineering.
Main area of focus: complete integrated automation of pre-production engineering for aircraft manufacture, using CALS technologies and mathematical modelling of production processes and tooling.
Scientist engineers in this area of research strive to develop bottom end data models for pre-production planning.
Most of the work here is practically oriented and helps to considerably widen the potential of CAD/CAM/CAE systems currently used at aircraft production plants.
In 2001, to efficiently achieve the tasks of pre-production engineering, a research and development laboratory "Automation of preproduction planning processes" (APP) was established in partnership with JSC "Yury Gagarin Aviation Plant" on the premises of the Dep. of Aircraft building technology.
As a result of the lab's work, several basic data models for pre-production engineering were developed, among them:

As a result of the lab's work, several basic data models for pre-production engineering were developed, among them:
- math models for production processes (operations) in press-forging, which (models) describe how the elements of a production system interact with the articles being manufactured;
- engineering models that describe structural and performance properties of items produced by the elastic medium;
- models of a production (process) medium that include a structural and logical description of some elements of production tooling, in particular of bending equipment for elastic medium press forming.
These models have become a basis for object-oriented software automation systems used for the purposes of pre-production engineering in press-forging industry, which makes it possible to design forming tools with regard to the spring back of materials after removal of a resistive load; these systems were developed and successfully implemented.
Today the results of theses researches have led to one doctoral and six PhD dissertations having been prepared and successfully defended.
