George Foster Professor of Chemistry before gaining emeritus status in 2019, Dr. Hark is the recipient of several awards for teaching excellence and is the author of over 35 publications. His early work included the synthesis of complex natural products and the development of novel reagents for visualizing latent fingerprints, a project conducted in conjunction with the US Secret Service. Prior to joining IPCH Dr. Hark's research efforts were focused on the application of analytical and imaging techniques to the study of cultural heritage objects, the analysis of geological materials, and items of forensic interest using laser-induced breakdown spectroscopy (LIBS), and the synthesis of isotopically labeled organic compounds. His current work includes diverse projects involving scientific analysis of the Vinland Map and its sister manuscripts, 16th to 18th-century British portraiture, the Gutenberg Bible and related incunables, 15th-century tarocchi cards, and William Henry Fox Talbot’s The Pencil of Nature. His work on the analysis of art and artifacts has been published in a variety of journals, including Applied Spectroscopy, Journal of Archaeological Sciences, Journal of Raman Spectroscopy, Materia: Journal of Technical Art History, and Proceedings of the National Academy of Sciences. Dr. Hark previously spent sabbatical leaves at IPCH, University College London, and the Victoria & Albert Museum plus he has collaborated with researchers at Winterthur Museum. He also taught a multidisciplinary course called “The Chemistry of Art” for many years, often in conjunction with an art historian.

Andreas Hochuli trained as a violin maker at the Swiss Violin Making School in Brienz. From 2011 he studied conservation and restoration at the Bern University of the Arts, which he completed in 2016 with his master's thesis on the subject of varnish supplements on historical stringed instruments. Since then, he has been working as an independent restorer for stringed instruments in his own studio in Bern. At the violin making school in Brienz, he teaches introductory courses on topics related to the conservation and restoration of stringed instruments as well as photographic documentation. From 2019 to 2020, he was involved as a research associate in a research project between Empa and BUA on cellulose-based adhesives for wooden cultural objects. Since September 1, 2021, Andreas Hochuli has been employed in the Department of Conservation and Restoration at BUA as a research assistant in the studio for paintings and sculpture. Among other things, he accompanies students in the use of photographic documentation techniques and digital 3D photogrammetry.

Libby Ireland is a Sculpture and Installations Conservator at Tate with a focus on new acquisitions into the collection. She has been a researcher for two case studies for the Tate research project Reshaping the Collectible: When Artworks Live in the Museum. These looked at processes for replication, remastering and refabricating at Tate, and the acquisition and display of five works by Ima-Abasi Okon. Her research for the latter focussed on reframing the relationship between museums and artworks as host and guest, advocating for deliberate slowness as an enactment of radical hospitality. Ireland’s research interests also include modern materials and fabrication processes, and she has undertaken research into conservation of additively manufactured artwork components. This involved development of documentation methods collaboratively with the Science Museum to ensure key technical information is gathered, and to prompt conversations about associated digital files and reprinting at the point of acquisition. Ireland is active in the conservation community, co-founding the Icon Emerging Professionals Network in 2017 and Tate’s Collection Care Sustainability Group in 2020.
