He is the founder and director of Energy Safety Research Institute (ESRI) at Swansea University, which consolidates the energy research at the University with a focus on environmental impact and future security. At Rice University, he leads a Research Group and has served as Associate Dean for Industry Interactions and Technology Transfer.

Most of Barron's work has revolved around the study of nanoparticles and their applications. Early on, he studied how the structure of a molecule could overcome thermodynamic control and create new solid state structures. Some of his early work also dealt with alumoxanes and ceramic nanomaterials. In the early 2000s, his research began to focus on carbon nanonmaterials, the functionalization of fullerenes and single walled carbon nanotubes. Later, application of nanontechnology to energy problems became the focal point of his work. He has authored over 440 papers and 6 books, including a book co-authored with his wife, Merrie Barron, entitled Project Management for Scientists and Engineers.

Barron is the co-founder of several companies in the industry of oil and gas, solar energy, and water treatment. He was a co-founder of the Rice Alliance.

Over a three decade long career, Barron has received several awards for his research and work. He received the Hümboldt Senior Scientist Research Award in 1997, the Welch Foundation Norman Hackerman Award in Chemical Research in 2002 and the Lifetime Achievement Award by Houston Technology Center in Nanotechnology in 2011. He is a fellow of the Royal Society of Chemistry.

Early life and education
Barron was born in Welwyn Garden City on 20 May 1962. He was raised in Farnham, Surrey, where he attended Heath End School and Farnham Sixth Form College. He was classmates with Michael Ball and often participated in theatre with him. In 1983, Barron completed his BSc in Chemistry from Imperial College. Subsequently he received his PhD degree in 1986 from Imperial College under the supervision of Geoffrey Wilkinson.

After completing his PhD, Barron moved to the United States and joined University of Texas Austin for his post-doctoral research, which dealt with the chemistry of multiple bonds to phosphorus and carbon. He published the first structural characterization of a C≅P triple bond in 1988 in a paper he co-authored with Alan Cowley. In 1987, he joined Harvard University as an assistant professor of Chemistry and was promoted to Associate Professor in 1991. Barron founded Gallia inc. in 1992 and became Chairman of the Scientific Advisory board.

Later Career
Barron left Harvard University in 1995, when he joined Rice University as professor of Chemistry and Materials Science. He stepped down from his position at Gallia in 1997. In 1998, he was appointed as the Charles W. Duncan Jr.-Welch Foundation Chair in Chemistry at Rice University. There he created the first educational programs that combined Science, Engineering and Management.

Following his studies on ceramic nanoparticles and the discovery of their applications, he founded Oxane Materials Inc. in 2002. The company developed nanoproducts with applications in the field of energy. Building on his research with nanoparticles, Barron founded Natcore Technology in 2004 and joined the scientific advisory board of the company. The company manufactures nanoparticles and technology with applications in the solar sectors.

From 2006 to 2008, he served as the Associate Dean of Industry Interactions and Technology Transfer at the institute. In 2013 he was appointed as the Sêr Cymru Chair of Low Carbon Energy and Environment, College of Engineering, Swansea University. He taught as a visiting professor for one year at University of Wales in 2009.

In 2010, he founded a program for water purification in developing regions of the world. He has served as a board member of the Houston Clean Energy Park. His research in the field of energy resulted in the foundation of Energy Safety Research Institute, which he leads, at Swansea University.

Barron is the editor of Journal of Nanomaterials since 2013 and Scientific Reports since 2014. He is also part of the editorial boards of Main Group Chemistry and Materials Science in Semiconductor Processing. Barron has served on the advisory board of King Abdullah University of Science and Technology, Zhu Zhou International Research Institute China, and Yellow River Delta Efficient Eco-economic Development.

Molecular control over solid state structure
In the early 1990s, Barron developed interest in studying how the structure of a molecule could overcome thermodynamic control and create new solid state structures. As such, he synthesized a class of cubic Gallium chalcogenide compounds and showed for the first time that a new meta-stable phase could be synthesized. Subsequently, Barron showed that such phases had practical applications.

Alumoxanes
In creating a range of cage structures, Barron started to think about the elusive structure of the polymerization co-catalyst methylalumoxane (MAO). Following from his work on the chalcogenides, Barron was the first person to crystallographically characterise an alumoxane in 1993. These structures were the first to be spectroscopically consistent with methylalumoxane; however, it was not clear of their mode of reactivity until Barron once more showed that despite being octet molecules they had significant Lewis acidity, he termed this as “Latent Lewis acidity”, and showed that this mechanism applied to a number of MAO style polymerization systems. Barron’s model has been evolved by others but is essentially the same as now widely accepted.

Ceramic nanomaterials
While investigating MAO-like structures, Barron noticed the relationship between clusters and minerals, at the same time he became interested in so-called metalloxane polymers. Combining his experience he determined that these "polymers" were actually nanoparticles. Furthermore, he showed that these metal oxide nanoparticles could be chemically made by a top-down approach from mineral with which they shared their structures. With the ability to make a range of nanoparticles with different functional groups and control over size, Barron found that the structure and physical properties of macroscopic materials could be controlled by alterations at the nanometer scale.

One physical parameter that the nanoparticle showed an ability to control was the final pore size and structure of a ceramic. In particular, Barron was the first to discover that nanoparticle derived ceramics could be designed to have intra-granular porosity (i.e., the pores are within the crystal grain rather than between the crystal grains as normally observed). This has implications in composites but also in membranes and separation processes. Barron spent significant time investigating how changes in chemistry could affect membrane performance. However, it was the ability to create unusual structures that led to Barron developing a process that forms hollow spheres of ceramic with exceptional crush strength.

As with his work on molecular control over solid structure, Barron conceptualized how these structures could have real-world applications. Barron rationalized that if hollow ceramic spheres could be made on a large scale they could replace dense ceramics being used in oil extraction and minimize waste. He created a spin-of company to commercialize this technology, which has applied its material to near 30 oil wells with increased production up to 30% greater than comparable wells.https://www.sciencedaily.com/releases/2017/07/170719100524.htm Enhanced oil recovery method developed In 2010, Barron and his team, on the request of U.S. Navy, developed a ceramic membrane with microscale pores that could filter out contaminants from waters and protect divers' wet suits without getting blocked. https://www.theengineer.co.uk/swansea-filter-fracking/ Swansea filter could help reduce environmental impact of fracking

Carbon nanomaterials
The study of how the surface of a nanomaterial behaved led Barron to investigate how a nanomaterial can alter the behavior of biological molecules. By first synthesizing a C60-derived amino acid that was stable to hydrolysis, he was able to investigate the impact of a fullerene on wide range of systems. Initial work was concerned with the toxicity on various cell types. The results of this work demonstrated that inclusion of C60 into a pepetide structure drastically lowered any toxicity effects. Not only did Barron and his collaborators demonstrate that the presence of a C60 substituent enabled peptides to successfully transport through cell walls, but they also demonstrated an almost unique ability of fullerene amino acids to enable peptides to transport through skin.

In his latest work, Barron has studied catalysis with growth of single walled carbon nanotubes (SWCNTs). He pioneered the concept of amplification of a CNT. By the attachment of a suitable catalyst to the end of a CNT he has shown that the length of the tube can be increased, thus paving the way for the possible growth of a single chirality of CNT. Barron has also investigated the complex system in a systematic manner much like the studies of polymerization catalysis. His work is focused on understanding the chemical controls over the structure of a CNT based upon the catalyst that is used for its growth.

Environmental research
The experience gained in understanding the surface modifications of ceramic nanoparticles, coupled with his work on membranes and water purification has meant that Barron has recently returned to the issue of water purification. With the public concern over hydraulic fracturing and the waste and contaminated water in particular, Barron has investigated the nano control over the surface of a material that allows for the creation of both super hydrophilic surfaces that allow for separation of oil and water without fouling and also the creation of surfaces that wet such that viruses and bacteria can be trapped.

Most recently, his research has been focused on energy problems including sustainable resources and waste recovery, reducing the impact of hydrocarbon energy sources, carbon dioxide valorisation and long-term sequestration and the next generation of the energy distribution.

Personal life
Barron lives in both Swansea (Wales) and Houston (Texas). Since he moved to Texas in 1990s, he has participated in motor racing as a sport. In 1999 American Lemans Series, he was team principle for the GTS Team. He participated in the final season of USRRC under Ross Racing. Barron has previously raced Lotus Seven, Caterham Seven, and Lotus Type 61 Formula Ford. He has been SW Division SCCA E-Production Champion, 2013 Monoposto Formula Ford Champion, 2013 SVRA Group 2 Sprint Series Champion and 2014 Monoposto Formula Ford Champion. In 2018, he raced FIA Formula Opel Racing with a Formula Vauxhall Lotus.
