PhD position – Bioreactor modeling and simulation

Last date to apply: 31.01.2026
Number of Positions: 01

Our Profile

At the Institute of Applied Microbiology, RWTH Aachen University, we develop next-generation biotechnological processes to convert sustainable resources into valuable products, using synthetic biology, fermentation, data analysis, and modeling to address global environmental challenges and advance an industrial-scale, sustainable bioeconomy.

To support our aims, we are searching for a PhD student in computational biotechnology and modeling and simulation of fermentation processes, respectively, as a new member for our recent project FrameBio (Multiscale Frameworks for BioSolutions) funded by the European Union through the Horizon Europe, Marie Skłodowska-Curie Actions (MSCA) grant. FrameBio’s goal is to revolutionize biotechnology by developing comprehensive computational modules that simulate microbial behavior of bioproducts (for food applications, such as Single Cell Proteins) and quantifying its resource dependencies across various scales: Microorganism Design and Engineering – Fermentation Design of Experiments coupled with High Throughput Screening – Commercial Production Scheme Simulations – Supply Chain Design – Planetary Resource Utilization and its Impact on Earths Geophysical Synergies, to predict the broad sustainability impacts of BioSolutions.

This PhD position is part of a Doctoral Network (DN) that will train 13 PhDs in genomics, metabolomics, fermentation and process optimization, and data science and sustainability assessments in a unique venture. Secondments at the Technical University of Berlin and the Bio Base Europe Pilot Plant in Belgium, lasting a total of six months, are integral parts of the PhD program.

Your Profile

The successful applicant has

• University degree (Master’s or equivalent) in bioinformatics, biotechnology, process engineering, mechanical engineering or equivalent programs
• At the time of hiring, applicants must not have lived in Germany for more than 12 months in the last 3 years or have carried out their main activity (work, studies, etc.) there. 
• Good programming skills
• Experience in modeling and simulation of fluid dynamics, preferably for bioreactor environments
• Basic biological knowledge of microbial metabolism and fermentation processing
• Good written and spoken English as well as presentation skills
• Excellent interpersonal, and organizational skills with an ability to work efficiently both independently and in a team
• a creative, open, and resilient mind

Your Duties and Responsibilities

This position is an exciting opportunity to work on a seminal topic and use cutting-edge technologies towards our vision of a sustainable bioeconomy. Your specific tasks will be:

• Setup, validation, and evaluation of Computational Fluid Dynamic (CFD) models for the elucidation of bioreactor heterogeneities.
• Development and application of compartment modeling approaches for approximating CFD results.
• Analyze and interpret data from scale-down and scale-up experiments.
• Collaborate on strain and fermentation process design efforts.
• Participate in scientific conferences, write scientific manuscripts, and supervise student projects and internships.
