DESCRIPTION:Professor Katalin Barta (Professor at the Faculty of Science 
 and Engineering\, Synthetic Organic Chemistry\, Stratingh Institute for Ch
 emistry\, University of Groningen\, Netherland). Katalin started her inde
 pendent career at the Stratingh Institute for chemistry at the University 
 of Groningen in 2013 where she was promoted to Associate Professor in 2017
 . She obtained her Master’s degree in chemistry from ELTE Budapest (Hung
 ary). Her master’s research was in the area of alternative solvents and 
 fluorous biphase chemistry under the supervision of Istvan T Horvath. Then
  she completed her PhD (2008) under the supervision of Walter Leitner in a
 symmetric catalysis and ligand design at RWTH-Aachen\, Germany. After\, sh
 e carried out postdoctoral research (2008-2010) with Peter Ford at Univers
 ity of California\, Santa Barbara and subsequently worked as Associate Res
 earch Scientist (2010-2012) at Yale University\, the Center for Green Chem
 istry and Engineering (New Haven\, USA) with P. T. Anastas. Her post-docto
 ral work focused mainly on the catalysis and renewable resources\, includi
 ng lignin valorisation. Combining various fields\, the research interests 
 in the Barta group are broadly in Sustainable and Green Chemistry\, focusi
 ng on the development of novel homogeneous and heterogeneous catalytic str
 ategies for the conversion of all main components of lignocellulose\, util
 izing Earth-abundant metals. Katalin is recipient of the ERC starting gran
 t 2015\, and the VIDI award of the NWO. She is funding member and secretar
 y of the EuChemSoc division Green and Sustainable chemistry and member of 
 the YAE (Young Academy of Europe).\nAbstract: In order to achieve true eco
 nomic feasibility of future biorefineries\, it should be ensured that maxi
 mum value is derived from all individual components of lignocellulose.[1] 
 Especially the catalytic conversion of the lignin component to well define
 d aromatic compounds has proven challenging.[2] Furthermore\, the downstre
 am processing of the platform chemicals obtained from cellulose(s) and lig
 nin still needs significant improvement in order to access sufficient dive
 rsity of products\, ultimately covering an entire value pyramid of new bio
 -based materials.\nImportantly\, research questions need to be re-designed
  to maximize material balance\, energy efficiency and sustainability in th
 e new catalytic pathways and globally.\n\nIn this lecture I will describe 
 our “cleave and couple” strategy\, where “cleave” refers to the ca
 talytic deconstruction of lignocellulose[2] or lignin[3\,4] to aromatic an
 d aliphatic alcohol intermediates\, and “couple” involves the developm
 ent of new transformations for the formation of C-C and C-N bonds[2\,5\,6]
  in order to obtain a range of products from lignocellulose.\n\n[1] Nature
