Research in the Morrill group is focused in the field of Synthetic Organic Chemistry. We are particularly interested in exploring new frontiers in organocatalysis, employing dual catalytic methods to rapidly generate molecular complexity, forming densely functionalised molecules in a stereodefined fashion. The multi-step, one-pot nature of this dual catalysis approach represents progress towards more sustainable chemistry. The development of novel organocatalysts, especially those that operate via unusual or previously unknown modes of activation, represents another significant area of interest. The utility and impact of our developed methodologies will ultimately be exemplified through its application in the total synthesis of natural products and molecules of biological significance.

Louis was born in Wick on the north coast of Scotland and obtained his MChem degree (1st Class Honours) from the University of St Andrews, including a one-year industrial placement at AstraZeneca (Charnwood). He completed his Masters research project in 2010 with Professor Andrew Smith.
Staying at St Andrews, he completed his Ph.D. under the direction of Professor Andrew Smith entitled "Organocatalytic Functionalisation of Carboxylic Acids Using Isothioureas", funded by a prestigious Carnegie-Caledonian Scholarship (2010-2014). This work expanded the utility of isothioureas in Lewis base catalysis and demonstrated the first intermolecular bond-forming reaction of carboxylic acid-derived ammonium enolates
For his postdoctoral research, he moved to UC Berkeley to join the research group of Professor Richmond Sarpong, entering the world of complex molecule synthesis. Specifically, he was part of a team that developed highly efficient and concise total syntheses of diterpenoid alkaloid natural products. In 2015, he was appointed as a University Research Fellow in Synthetic Organic Chemistry at Cardiff University and began his independent research career. He is specifically interested in exploring new frontiers in organocatalysis.

Research in the Morrill group will be underway from October 2015 and areas of interest will include:
- The exploration of new frontiers in organocatalysis via the productive merger of organocatalysis with other transition metal, organometallic or biochemical modes of activation.
- The development of novel Lewis acid organocatalysts for a variety of organic transformations.
- Expanding the utility of neglected, yet readily available and cheap precursors in organocatalytic transformations.
