Summary

Dr. Minh-Son Pham is a Lecturer (equiv. to Assistant Professor in USA) in the department of Materials. Previously, he was a Research Associate at Carnegie Mellon University and a Guest Researcher at NIST. He obtained a Doctor of Science degree from the Swiss Federal Institute of Technology (ETH) Zurich with distinction - ETH Medal. His groundbreaking research has been published in Nature, Nature Communications, J. of Mech. and Phys. of Solids, Int. J. of Plasticity, etc. He has delivered > 15 invited lectures at international conferences (Programmable Materials 2020, ICMAT2019, Thermec, TMS etc.)

He currently leads a research group of 10 PhD students and 1 postdoc to carry out fundamental research in additive manufacturing (ie 3D printing) and digital manufacturing, microstructure, mechanical integrity andmeta-materials. He establishes strong collaborations with industries across different sectors from aerospace, gas & oil, defence, automobiles, medical devices (orthopaedics and atrial fibrillation treatment) and energy (including fusion with CCFE) to help tackling challenges related to reliability, functionality, sustainability and environmental issues in these sectors. More additional details about his research can be found at:  Pham personal webpage

He teaches multiple subjects at Imperial: Failures of Materials, Additive Manufacturing (i.e. 3D printing), Microstructure of Steels. Dr. Pham is a placement coordinator and careers adviser in the department of Materials.

Dr. Pham currently coordinates the international exchange programmes in Materials and Nuclear Engineering between Imperial and other world leading universities including MIT, Purdue, EPFL and ETHZ.


Research:

META-MATERIALS & PROGRAMMABLE MATERIALS: 

Our groundbreaking study "Damage-tolerant architected materials inspired by crystal microstructure, Nature, 565, 305-311 (2019)" presents a transformative approach to combine the science of metals with 3D printing to generate extraordinarily tough and lightweight meta-materials with desired properties, holding great potential for a variety of applications. 

The study has been highlighted by  > 15 media channels (in English, Dutch, Korean): Imperial College's webpage, Physics World, Chemical & Engineering News, Dutch Newspaper NRC, Science News, EurekAlert, Nature Korea, University of Sheffield, & many more

ENERGY (INCLUDING FUSION)

We have studied the mechanical integrity of structures and components in power plants such as thermal fatigue of austenitic stainless steel in primary cooling circuit in nuclear power plants. Led by Dr. Catrin, we currently work with experts in UK Atomic Energy Authority - Culham Centre for Fusion Energy to study the fatigue-creep interaction of critical components, helping to realise future power plants powered by green energy source - fusion.
