Lewis is joined by two student co-hosts, Kavi Shama and Matt Turton, to discuss what Materials Science is with this month's expert, Dr Kathy Christofidou.

 is a final year PhD student with the AMSCDT and is researching the cladding behaviour of high enrichment and high burn-up nuclear fuel: determining the impact of radiation damage on storage and corrosion. Kavi admits he is not the biggest cake fan, and instead would rather reach for a KitKat Chunky.
  is a second-year PhD student, he graduated from the University of ºù«Ӱҵ with an MEng in Materials Science and Engineering in 2022. Matt is currently investigating the local structure of high entropy alloy with the aim of linking this to any properties of interest for nuclear fusion first shield wall applications. In his spare time, Matt enjoys playing rugby and going climbing, and says a Jam Roly-Poly is his favourite cake.
They're both members of Lewis and Kathy's research group; Modern AlChEME (see link below).

 is a Senior Lecturer in Metallurgy at the University of ºù«Ӱҵ, Technology Platform Lead for the Henry Royce Institute in Materials Discovery and Prototyping, co-leads the Modern AlChEME research group, and is Admissions Tutor. In lieu of a more traditional cake, Kathy's favourite dessert is Profiteroles. 

Lewis is joined by a new student co-host, Frances Livera, to discuss how to find a solution we first need to properly define the problem with this month's experts, Professor Iain Todd (professor of Metallurgy) and Dr David Bowden (UK Atomic Energy Authority).

 is a final year PhD student within the Advanced Metallic Systems CDT. Her research looks into brazing of additively manufactured components and how these joints differ from brazing on more traditionally manufactured materials. She is also an active member of the wider University of ºù«Ӱҵ Engineering community and co-chair the Engineering PGR Student Committee, which aims to improve the experience of PGRs within the Faculty. Outside of work, Frances can be found crocheting, sewing, or exploring the Peak District (with snacks in hand, often a cake made by fellow PhD researcher and upcoming podcast guest Lucy, of which her favourite is coffee and walnut)! 

is an international authority in the field of powder metallurgy and additive manufacture (AM or 3D printing) of metals and alloys. His work focuses on enhancing the manufacturing rate while simultaneously improving component quality and structural integrity. His work is conducted in close collaboration with industry and on an appropriate scale to allow rapid transition of laboratory discoveries into industrial practice. He is highly sought-after by industry for his expertise, and his experimental results and insights have been exploited by the AM and aerospace sectors to solve important engineering challenges in the development of additive manufactured aeroengine and aerostructure components.

His team are primarily focussed on developing new high temperature steels for operation within a fusion reactor breeder blanket. David has had what he describes as quite a meandering engineering career so far, moving from aerospace, to maritime and now to nuclear. In his free time, between looking after his baby daughter, David enjoys continuing engineering at home, with a 3D printer, and combining this with hobby electronics he learnt during the many months of lockdown in 2020/21. Without pausing for breath David declared carrot cake his all time favourite.

Lewis is joined by guest student cohost Josh Berry in this episode, and expert panel Dr. Claire Utton and Prof. Hector Basoalto.

In this episode Lewis welcomes student co-hosts; Ben Jolly and Jacob Whittle to talk all things Advanced Manufacturing with expert Dr Felicity Freeman.

 and  are both in the third year of their PhD research with the AMSCDT.
Ben is currently researching the local structural behaviours of multi-component alloys via Neutron Total Scattering experiments. Encompassing a number of specialised materials of potential significance to nuclear and aerospace industries. He initially graduated with degree in Physics, studying Materials Science & Engineering seemed a natural progression to his scientific career. When not being driven to insanity by crystal lattices and Python code, he enjoys the seemingly-traditional ºù«Ӱҵ pastime of climbing, and watching the football with endless frustration. His favourite cake is his mum's Chocolate cake.
Jacob's PhD is in collaboration with , and he is a member of the Rail Innovation and Technology Centre. His research focuses on the sustainability of steel railway infrastructure and how it can be used to support low carbon transport systems worldwide. He is a Doctoral Supervisor of Railway Challenge at ºù«Ӱҵ, Graduate Teaching Assistant in the Faculty of Engineering and Open Day Ambassador in the Department of Mechanical Engineering, and is partial to a Carrot Cake. 

 is a lecturer in Mechanical Engineering with a background as a research associate working in additive manufacturing. Her PhD was in the development of magnetically-graded steels and using the Laser Powder-Bed Fusion additive manufacturing process (3D printing). Prior to this she spent 10 years working at Rolls-Royce as a Manufacturing Engineer. When asked to choose, she'd reach for the classic Lemon Drizzle cake. 

In this episode we shake things up a bit as we enter into Dr Lewis Owen's specialist field. So we welcome back Dr Kathy Christofidou, this time in the role of host as Dr Lewis Owen sits in the 'expert' seat, and they're joined by doctoral researcher Frances Synnott.

 is a PhD researcher at the University of ºù«Ӱҵ with the Advanced Metallic Systems Centre for Doctoral Training. Her research is sponsored by Rolls-Royce and involves developing superalloys to improve future jet-engine applications.

In lieu of a more traditional cake, Kathy's favourite dessert is Profiteroles. 

Lewis, alongside student co-host Lucy Farquhar, discuss sample testing with expert Prof. Russell Goodall.

 researches the development of refractory high entropy alloys for additive manufacturing. She's a runner and plays netball a lot, aswel as being an avid baker. Asking her to choose a favourite cake is like asking a parent to pick their favourite child!

 spends his time at work studying metals and thinks that the periodic table is the best map ever created. Outside of work he likes the more normal kinds of maps and trying to persuade his children to go on walks. He likes exploring unknown alloys - combinations of different elements in the periodic table - with the aim of finding unusual (and hopefully useful) behaviours. His favourite true cake is a Victoria Sponge, but if there is millionaire's shortbread, he'd choose that.

PhD researcher Durga Tilak is Lewis's co-host in this final episode of the series. They talk all things recycling, sustainability and long term storage in the world of materials science with expert Dr. Richard Thackray.

 is in the second year of her PhD in eddy current reduction in automotive permanent magnets in collaboration with Volkswagen.
