Role Profile
The School of Chemical Sciences (SCS) at Dublin City University (DCU) invites applications for a Postdoctoral Researcher as part of a new collaborative project between DCU, HT Materials Science Ltd (HTMS) and Exergyn Ltd. This project, DLCool, has been awarded under the seventh round of the Disruptive Technologies Innovation Fund (DTIF7). The main goal of the DLCool project is to accelerate the development and deployment of next generation heat transfer fluids for use in solid‑state heat pumps, direct to chip cooling and other applications, such as EVs and battery storage systems.
The focus of the successful candidate will be to develop AI tools which accelerate the identification of candidate fluids, by applying machine learning, in particular physics‑informed neural networks (PINNs), to optimise the thermal properties of nanofluids for use in direct cooling systems. Expertise in the development and application of PINNs in material design is an essential pre‑requisite for this role.
As an industry‑academia collaboration, the candidate will work on real industry problems and contribute to developing technologies which will have a profound effect on environmental challenges worldwide.
Duties and Responsibilities
Develop AI tools for identification and optimisation of heat transfer fluids.
Apply physics‑informed neural networks (PINNs) to optimise thermal properties of nanofluids.
Collaborate with industrial partners in HT Materials Science Ltd and Exergyn Ltd.
Contribute to the design and testing of direct cooling systems for EVs, battery storage systems, and solid‑state heat pumps.
Qualifications and Experience
PhD in materials science, mechanical engineering, physics, or related field with focus on machine learning or computational materials.
Expertise in developing and applying physics‑informed neural networks (PINNs) for material design.
Strong programming skills in Python, machine learning frameworks (PyTorch, TensorFlow) and scientific computing.
Experience with high‑performance computing and simulation of nanofluid behaviour.
Excellent communication skills and ability to work cross‑discipline.
Essential Training
* Orientation
* Health & Safety
* Data Protection (GDPR)
* Cyber Security Awareness
* AI Literacy
Other Training May Need To Be Undertaken When Required
