Amin Rahmat is an Assistant Professor in Soft Matter Modelling at the School of Chemical Engineering at the University of Birmingham. He is a computational scientist leading multidisciplinary research on the interfaces of fluids and solids. His research mainly focuses on developing computational models for microscale multiphase flows and fluid-solid interactions, with particular interest in resolving physics-driven interfacial singularities.

Amin’s interdisciplinary research is at the interface of chemical engineering, applied mathematics, bioengineering, and healthcare. He has the experience of working with academics with diverse backgrounds e.g., from engineering, applied mathematics, chemistry, medicine, etc. He has collaborated with more than 30 international researchers forming an active growing network of collaborations. He has published more than 20 peer-reviewed articles in high-impact journals.


  • PhD in Mechatronics engineering 2017
  • MSc in Mechanical engineering 2012
  • BSc in Mechanical engineering 2009


Dr Rahmat has a background in mechanical engineering with a focus in thermo-fluids. He graduated from his PhD in 2017 from Sabanci University in mechatronics engineering.

After a short postdoc position, he joined the University of Birmingham where he worked in three different schools i.e., Chemical Engineering (2018-2021), Mathematics (2021-2023) and the Institute of Metabolism and Systems Modelling at the Medical School (2023).

He re-joined the School of Chemical Engineering in 2024 as an assistant professor in Soft Matter Modelling.


Dr Rahmat research interests spin around computational modelling of soft matter problems. He mainly develops and extends hybrid multiscale models using particle-based methods e.g., Smoothed Particle Hydrodynamics and Coarse-Grained Molecular Dynamics. In terms of applications, his research divides into the following:

Physics-driven interfacial singularities at material interfaces

Dr Rahmat leads the computational modelling of singularities such as the dissolution and agglomeration of solid materials in fluidic environments, and membrane rupture and topological transformations of deformable microparticles. For more information, you can refer to:

Manipulation and control of interfaces using electrohydrodynamics

Dr Rahmat leads the modelling of dispersed multiphase systems under the effects of external electric fields to develop non-invasive, simple-to-use, cost-effective tools for manipulating dispersed fluidic systems. A few examples are the applications of electrohydrodynamics for droplet coalescence, electrojet printing, droplet deformation and dielectrophoresis in microfluidics.

Hydrogels and smart active stimuli-responsive materials

Dr Rahmat leads the numerical modelling of poroelastic stimuli-responsive hydrogels and other active porous materials with a focus on expanding biomedical applications of stimuli-responsive hydrogels e.g., multistage and directional drug release, soft implants, and wound dressing.
