Integrated Multiscale
Porous Media Research

Get Started Our Projects

The Integrated Multiscale Porous Media Research (IMPRES) Group, established and led by Professor Dr. Vahid Niasar in 2014, is dedicated to delivering innovative engineering solutions for a wide range of porous media topics. Our expertise spans subsurface hydrology, reservoir engineering, renewable energy, fuel cells, and batteries.
At the IMPRES Group, our team of researchers is at the forefront of developing cutting-edge computational and experimental techniques. We aim to investigate various aspects such as multiphase flow, reactive transport, solid-fluid and fluid-fluid interfaces, as well as non-classical theories of porous materials. By addressing these fundamental problems in science and engineering, we contribute to advancing knowledge in the field.
Our mission is twofold. Firstly, we strive to deepen our understanding of fundamental porous media processes. By exploring these processes at pore level, we gain valuable insights into their intricate mechanisms. Secondly, we are committed to improving numerical upscaling methods for multi-scale coupled problems. This enables us to bridge the gap between microscopic and macroscopic scales, facilitating more accurate and efficient modeling of complex systems. Our diverse research portfolio encompasses a wide range of topics, including:

  • Optical and X-ray imaging of porous materials,
  • Pore-scale modelling using GPU-accelerated pore-network modelling, Lattice-Boltzmann, and Volume-of-Fluid methods,
  • Darcy-scale, reservoir scale modelling and simulations,
  • Physics of porous media, flow and reactive transport in porous media.
Industrial Applications:
  • Subsurface energy engineering,
  • Geological CO2 and hydrogen storage,
  • Reservoir engineering and enhanced oil recovery,
  • Electrochemical energy engineering, e.g., fuel cells and flow batteries,
  • Soil physics and contaminant hydrogeology.

Testimonial of IMPRES alumni

Since 2014, I had the opportunity to collaborate with several talented PhD students and PDRA staff in IMPRES group.

The three years that I spent working with Prof. Niasar and the IMPRES group and the later continuous collaborative work, have been a pure pleasure on all levels. Serious scientific work is being done, including collaborations with renowned (inter-)national partners, in combination with a social and friendly environment, promoting all aspects of a professional well-being.

Dr Nikolaos Karadimitriou

Former PDRA during 2014-2017; Now

A collaborative, supportive environment with culture of curiosity and adventuring in the unknown with enthusiasm. It was a nice mix of science and socials.

Dr Rimsha Aziz

Former PhD student during 2015-2018; Now

During my time in IMPRES, I had the opportunity to improve my skills, develop new ones under Prof. Vahid Niasar’s supervision. I was part of a highly talented team with a wide array of different skills and a keen eye for quality research.

Dr Omar Emmanuel Godinez Brizuela

Former MPhil and PhD student during 2015-2020; Now

The experience in IMPRES group was great and eye-opening, and the chance to go to the Diamond Light Source twice was a cherished moment. Above all, the word of wisdom that I gain throughout my PhD journey is ‘Understand the subject matter and never memorize’

Dr Sharul Nizam Hasan

Former PhD student during 2016-2020, Now

As a post-doc, IMPRES was where I transitioned from being a research student to an independent academic starting a faculty position a year after my PhD. Along the way we produced excellent soil sustainability research working with groups across the North Sea.

Dr Daniel Magnone

Former postdoctoral researcher during 2017-2018; Now

Being part of the collaborative modelling group enhanced my exploratory research into novel concepts for predicting polymer electrolyte fuel cell performance. The connections I developed here have had long lasting impact on my career going forward.

Dr Daniel Niblett

Former PhD student during 2017-2021; Now

During my time at IMPRES as a PhD student I had the chance to work on both modelling and experimental aspects of flow and transport in porous media. I really enjoyed IMPRES dynamic, friendly, supportive, and collaborative environment.

Dr Hamidreza Erfani

Former PhD student during 2017-2020; Now

Being a part of IMPRES group is a fantastic and impressive experience. I would like to extend my sincere thanks to all group members, especially Professor Vahid Niasar, for their solid support.

Dr Senyou An

Former PhD student during 2018-2021; Now

I spent two years in IMPRES group. During this time, I published in reputable journals and improved my research skills a lot. I would thank Prof Niasar for his leadership and huge support. I would also cherish the happy memories with the colleagues. I wish that I could always be in IMPRES.

Dr Yongqiang Chen

Former PDRA during 2019-2021; Now

In the IMPRES group, I did a microfluidic visualisation experiment as part of my PhD research. These investigations assisted me in gaining a fundamental understanding of the flow of polymeric non-Newtonian fluids at the pore scale and enhancing the numerical approach.

Dr Takshak Shende

Former PhD student during 2019-2022; Now

During my time as a postdoctoral researcher at the IMPRES group, I embarked on an incredible journey that profoundly shaped my career. The experience was nothing short of fantastic, as it provided me with a rich and vibrant environment for academic growth and personal development.

Dr Mohammad Javad Shojaei

Former PDRA during 2020-2021; Now

IMPRES exemplifies collaborative research and innovative thinking. Learning to critique my own work before external feedback, was a key lesson. Our teamwork culture and diversity of research topics made every interaction a learning opportunity. We celebrated friendship while exchanging ideas that transcended disciplinary boundaries.

Dr Javad Shokri

Former PhD (2019-2023); Now
