Early life and education
Coleman attended the King's Hospital School, before studying for a BA in experimental physics in Trinity College Dublin.[4] He graduated with First Class Honours and a gold medal in 1995. He completed a PhD in physics in TCD in 1999 under Professor Werner Blau.[5]
Research and career
Summarize
Perspective
Coleman became a lecturer in physics at TCD in 2001 rising to Professor of Chemical Physics (2011 - 2022) and later Erasmus Smith's Professor (2022 - present).[5] He is currently (2022) the Head of the School of Physics in TCD and a member of the University Council.[1][6]
The theme of his research is the production and processing of nanomaterials in liquids. The main focus is liquid phase exfoliation of layered crystals such as graphite and inorganic layered compounds. This produces liquid suspensions of two-dimensional nanosheets such as graphene, BN, MoS2 or MoO3. Such liquid processing allows the production of coatings, thin films and composites. These structures are useful in a range of applications in areas such as: reinforced composites, transparent conductors, sensors, optoelectronic devices and electrodes for batteries, solar cells, supercapacitors, etc. He has also performed research on other nanomaterials such as carbon nanotubes and metallic nanowires.[7]
In addition to his publications on liquid phase exfoliation of graphene[8] and other layered materials,[9] he has published a number of papers on applications of solution processed 1D and 2D materials. Examples include: the demonstration of highly sensitive polymer-graphene composite strain sensors;[10] printed nanosheet-based transistors[11] and high-capacity lithium-ion batteries.[12]
Coleman is most well known for the development of liquid phase exfoliation, a widely used method for preparing graphene and other two-dimensional nanosheets.[3][8] Coleman's papers have been cited 120,000 times yielding a h-index of 125.[13] He has been included on a number of highly cited researchers lists including the list of scientists with h-index beyond 100[14] and the Clarivate Highly Cited Researchers list.[15] To date he has been awarded four ERC grants.[16] He has supervised 38 PhDs and mentored notable scientists like Prof. Valeria Nicolosi (Trinity College) and Prof. Claudia Backes (University of Kassel).
He has given a number of public talks, for example the Irons Lecture at Rutgers University in the United States in April 2017,[17] and the Jacobus van ‘t Hoff Lecture at TU Delft in June 2022.[18] He also participated in the ERC-organised TEDx-Brussels public [19] talks.

Awards and recognition
Coleman was named the 2011 Science Foundation Ireland Researcher of the Year[20] and was awarded the Kroll Medal from the Institute of Materials in 2012.[21] In 2011, he was named among the top 100 Materials Scientists of the previous decade by Thomson Reuters.[22] In 2018 he was named the ACS Nano Lecture Awardee by the American Chemical Society,[23] and in 2022 was awarded the Tabor Medal by the Institute of Physics.[3]
In 2023, he received the Royal Irish Academy Gold Medal in the Physical and Mathematical Sciences, one of Ireland's highest academic honours.[24]
He is also a Member of the Royal Irish Academy (MRIA),[25] a Member of the European Academy of Sciences (EURASC),[26] and was elected a Fellow of the Royal Society in 2025.[27] The Royal Society cited his "pioneering work on liquid phase exfoliation, which revolutionized the scalable production of two-dimensional materials and enabled their application in electronics, energy storage, and composites."
