Background
- Doctoral candidate, TUM Graduate School - CeDoSIA, now part of GC-CIT
- Research Associate (Wissenschaftlicher Mitarbeiter) at TUM SCCS, April 2018 - March 2024. Guest since then, currently on a similar position at the IPVS, University of Stuttgart.
- M.Sc. in Computational Science and Engineering, Technical University of Munich, 2017
I was supported by a DAAD scholarship and I highly recommend to apply if you want to study in Germany. - Diploma in Chemical Engineering, National Technical University of Athens, 2014
- From Heraklion, Crete, Greece
Note: I frequently use the easier (but unofficial) form of my name "Gerasimos" → "Gerasimakis" → "Makis".
Research interests
- Multi-physics, black-box coupling
- Geometric multi-scale modeling (1D-3D, 2D-3D coupling)
- Fluid-fluid, multi-model coupling
- Fluid-structure interaction (FSI), Conjugate heat transfer (CHT), Computational fluid dynamics (CFD)
- Research software engineering, software sustainability, documentation, testing, continuous integration, fostering software communities
Research projects
- Co-developer of preCICE, a free/open-source solver coupling library for multi-physics simulations with long history and users in several countries. As this project grows and targets users outside our research group, I am also interested in good software engineering practices, as part of the research project preDOM. (2017 - 2020)
- Project ATHLET-preCICE, together with GRS (2019 - 2022)
- Dissertation with working title "A Sustainable Software Ecosystem for Complex Geometric Multi-Scale Coupling", also studying preCICE as a sustainable ecosystem of components beyond the core library (2018 - today)
Open and running student projects
If you are interested in a student project (Bachelor's or Master's Thesis or anything else), please contact me directly, with a few details on what you are interested in and describing your experience with simulations and related tools. I am mostly working with preCICE, for which you can also see our student projects with preCICE. See also the page of my colleague Benjamin Rodenberg, as well as the Student Projects at our chair.
Prof. Philipp Neumann in HSU Hamburg is also looking for students to work on preCICE-related topics.
Do you want to know what other students are working on in our chair? You are warmly encouraged to attend their presentations at the SCCS Colloquium! Come to get ideas, meet your potential supervisor, or to learn from the style of others for your own presentation.
Open student projects
I am not currently looking for new projects.
- Valentin Seitz was a student assistant contributing to the restructuring of the CSE Primer course and to the development of the preCICE system tests.

He is now continuing with the preCICE team as a doctoral candidate in IPVS, Univ. Stuttgart.
- Konrad Eder was a student assistant for the ATHLET-preCICE project. He was assisting in testing preCICE and in bringing preCICE to Windows.
- Francisco Espinosa did his Master's Thesis for M.Sc. CSE. The title of his thesis was "A flexible approach to 2D-3D coupling of a Shallow-Water Equation solver to OpenFOAM".
- Qunsheng Huang did his Master's Thesis for M.Sc. CSE. The title of his thesis was "Loose Coupling of Isolated Rotorblade Rotorcraft CFD/CSD Simulations using preCICE". This work was in collaboration with the TUM Chair of Helicopter Technology. He is now continuing as a doctoral candidate in our chair.
- Qunsheng Huang was also a student assistant. After finishing his thesis, he developed tests for the OpenFOAM adapter for preCICE.
- Ayman Noureldin did his Master's Thesis for M.Sc. CSE. The title of his thesis was "A Master-Slave Approach for Multi-Phase Fluid-Fluid Coupling of OpenFOAM and ATHLET". This work was in collaboration with the GRS institute in Garching.
- Dmytro Sashko was a student assistant for the preDOM project. He further developed the web-based preCICE tutorial and he worked on testing, packaging, and distributing preCICE.
- Michel Takken was a student assistant for the preDOM project. He updated the Code_Aster adapter for preCICE for preCICE v2 and Code_Aster 14, he wrote documentation, prepared a tutorial simulation case, as well as a system test with Code_Aster and OpenFOAM.
- Moritz Gnisia was a student assistant. He modernized the code framework of the course "CFD Lab" and developed a CI infrastructure and auxiliary tools for the course.
Teaching
Between 2018-2024, I was continuously involved in several courses, primarily for the M.Sc. CSE. See my deRSE24 talk for an overview. I led redesigning the M.Sc. course Advanced Programming, as well as the onboarding course CSE Primer. For a few years, I also taught in the M.Sc. courses CFD Lab, FSI Seminar, as well as the B.Sc. seminar Scientists & Ethics, and assisted in Ferienakademie. In 2021, our proposal "Beyond CSE Primer: Onboarding for computational degree programs" was funded as part of the TUM Ideas Competition.

Appreciation
Working at SCCS and TUM in general is great, because of (among many other reasons):
- The academic freedom and independence / increased trust at doctoral candidates at SCCS, as well as the relaxed culture, the well-attended lunch and coffee breaks, and Philipp's espresso knowledge,
- The excellent and extremely helpful job done by the RBG (and by extent our local chair SysAds), including providing instances of BigBlueButton, Nextcloud, HedgeDoc, Matrix, managing the equipment in the computer rooms and seminar rooms we use for courses, streaming and recording our lectures (and even workshops) with TUMLive, printing our conference posters, and always replying very quickly and thoroughly,
- The really convenient TUMExam system to organize the personalization, correction, grading, and review of exams,
- The very dedicated team at ProLehre, offering training and advice regarding anything teaching-related,
- and many more.
Last but not least, each and every one at the preCICE team makes work feel easier and more fulfilling.
