Research Scientist (Computational Sustainability Division), IHPC

The Agency for Science, Technology and Research (ASTAR) in Singapore seeks a Research Scientist for its Computational Sustainability Division. This role involves R&D in computational fluid dynamics (CFD) to tackle urban sustainability and decarbonisation challenges. Candidates should have a relevant PhD and expertise in fluid dynamics, numerical methods, and programming. The position offers opportunities for professional growth and collaboration with industry partners.
Research Scientist (Computational Sustainability Division), IHPC
We invite applications from outstanding candidates to join a dynamic and highly collaborative team of scientists and engineers within the Computational Sustainability Division (CoS) at the Institute of High Performance Computing (IHPC), ASTAR. The successful candidate will contribute to research and development in computational fluid dynamics (CFD), addressing critical challenges in urban sustainability, marine and offshore decarbonisation, low-carbon and renewable energy, and related domains.


The role involves working on a broad spectrum of R&D projects, from foundational capability development to applied research, offering significant opportunities for professional growth and meaningful impact.


The key scope of work includes:



Developing advanced modelling and simulation capabilities for multi-physics, multi-component, and multi-phase fluid flow problems.
Designing and implementing Physics-Informed Machine Learning (PIML) models, including core methodologies for embedding governing physical principles into machine learning frameworks.
Developing physics-based, data-driven surrogate models and data assimilation techniques for flow-related problems and applications.
Working closely with multidisciplinary teams to develop and apply CFD codes across diverse application areas, such as environmental flows, hydrodynamics, turbulent flows, and dispersion modelling.
Collaborating with industry partners, affiliated research institutes, and other key stakeholders to translate research outcomes into real-world impact.

Job requirements include:



A strong academic background in physics and/or engineering, preferably with a PhD in Mechanical, Aerospace, Civil, Environmental, Chemical, Computational Engineering, Applied Physics, or a closely related discipline.
Solid understanding of core physics and engineering principles, including fluid dynamics, transport phenomena, and thermodynamics, with demonstrated expertise in multi-phase and multi-component flows.
In-depth knowledge of numerical methods for fluid flow simulations (e.g. finite volume methods, lattice Boltzmann methods, volume-of-fluid techniques) and experience with high-performance computing.
Experience in developing computational methods, including the use and customization of open-source CFD codes (e.g. OpenFOAM, Nek5000, Palabos); familiarity with optimization techniques (e.g. linear, nonlinear, and real-time optimization) is an advantage.
Proficiency in programming languages such as Python, C/C++, Fortran, CUDA, and/or Julia.
Experience with machine learning techniques, including neural networks and deep learning, is highly desirable.
Strong interpersonal and communication skills, with the ability to work effectively both independently and as part of a multidisciplinary team.
Good written and communication skills.
Self-motivated, resourceful, and committed to high standards of professional integrity.
