Curriculum Vitae

Tobias Averbeck studied chem­ical engineering at the TU Dortmund Uni­ver­sity since October 2011 and finished his bachelor thesis with the topic “Investigating the generation of an equipment module database for pumps” at the laboratory of plant and process design under the supervision of Prof. Schembecker in 2018.

He continued with the consecutive master at TU Dort­mund Uni­ver­sity and completed his master thesis on the topic of “Mixed-level Fractional-factorial Experimental Design for the Reaction Optimization of a Suzuki-Miyaura Cross-Coupling” at the laboratory of equipment design under the supervision of Prof. Kockmann and Dr. Brunschweiger in 2020.

Since February 2021 Tobias works as a re­search associate at the laboratory of Industrial Chem­is­try with Prof. Vogt and Dr. Seidensticker.

Research Topic

Thermodynamic equations of state such as NRTL or PC-SAFT are often used to model phase equilibria and mixing behavior, but they also often reach their limits and therefore offer the possibility to improve the prediction by augmentation with experimental data. Since there is by far not enough experimental data available for every possible combination of solvents and substrates, we apply both probabilistic and deep learning methods to predict them.

The current research focus is on the prediction of three-dimensional, i.e. temperature-dependent, mixture data using neural networks for nonlinear matrix completion.

The predicted data is used in the following re­search to determine the phase behavior of ternary systems, especially thermomorphic multi-phase systems (TMS), by means of thermodynamic models.

Surprisingly, water has played only a minor role in TMS so far. This potential needs to be tapped and evaluated. The homogeneous catalytic alcohol amination serves as a model reaction here.

Location & approach

The campus of TU Dort­mund University is located close to interstate junction Dort­mund West, where the Sauerlandlinie A 45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dort­mund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dort­mund-Dorstfeld” (closer to North Campus). Signs for the uni­ver­si­ty are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dort­mund.

To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.

TU Dort­mund University has its own train station (“Dort­mund Uni­ver­si­tät”). From there, suburban trains (S-Bahn) leave for Dort­mund main station (“Dort­mund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The uni­ver­si­ty is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.

You can also take the bus or subway train from Dort­mund city to the uni­ver­si­ty: From Dort­mund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dort­mund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dort­mund main station to the stop “Dort­mund Kampstraße”. From there, take U43 or U44 to the stop “Dort­mund Wittener Straße”. Switch to bus line 447 and get off at “Dort­mund Uni­ver­si­tät S”.

The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.

The H-Bahn is one of the hallmarks of TU Dort­mund University. There are two stations on North Campus. One (“Dort­mund Uni­ver­si­tät S”) is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
