Prof. Helen H. Fielding

Principal Investigator

Helen carried out her PhD under the guidance of Professor Tim Softley FRS (Cambridge and Oxford) and postdoctoral research as an 1851 Fellow under the guidance of Professors Ben van Linden van den Heuvell and Wim van der Zande (Amsterdam). She began independent research at King’s College London (Lecturer 1994-1997, Reader 1997-2002, Professor 2002-2003) and moved to UCL in 2003. She was Head of Physical Chemistry 2013-2018 and Chair of the Equality, Diversity and Inclusion Committee 2014-18, 2019-20, a Royal Society Leverhulme Trust Senior Research Fellow 2018-20. She is currently one of the Chemistry and Light Research Theme leads and the PI of the UCL Ultrafast Laser Facility.

Outside work, she enjoys spending time with her three children.

Dr. David Bacon

Ultrafast Laser Facility Manager

David received his M.Eng degree and PhD in electronic and electrical engineering from the Pollard Institute at the University of Leeds, UK, in 2013 and 2017 respectively. Throughout this time, his research focused on the development of optical-pumped Terahertz sources under the supervision of Dr. Paul Dean and Prof. Edmund Linfield. This research continued until 2019 after being awarded a 2-year-long EPSRC fellowship prize. Following this, he completed a 4-year-long postdoc in the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology, Okinawa, Japan. There he employed HHG (high-harmonic generation) and ARPES (angular-resolved photoemission spectroscopy) to the study exciton dynamics in 2D semiconductors. He started at UCL in September 2023. He came to UCL in September 2023 as the ultrafast laser lab manager. In addition to keeping the laser systems and transient absorption spectroscopy facility running, he is setting up a new capability for UV-pump-EUV-probe photoelectron spectroscopy in molecular beams and liquid microjets.

Outside of work, David likes travelling and cooking food with his wife.

Dr. Graham Cooper

Postdoctoral Researcher

Graham obtained his MChem from Oxford in 2012. For his final year project, he worked with Professor Stuart Mackenzie. He then remained at Oxford to carry out a DPhil, also under the guidance of Professor of Stuart Mackenzie, before undertaking postdoctoral research under the guidance of Professor Nick Walker (Newcastle, 2016-17), Professor Mike Ashfold FRS (Bristol, 2017-19), Professor Arthur Suits (Missouri, USA, 2019-22) and Professor Jan Verlet (Durham, 2022-23). He came to UCL in June 2023, and is using molecular beam and liquid-microjet photoelectron spectroscopy to unravel ultrafast photochemical dynamics in complex systems.

Outside work, Graham spends most of his time with his wife and baby daughter, with the limited remaining free time spent reading, playing board or video games, and hanging out with friends and family.

Dr. Johanna Rademacher

Postdoctoral Researcher

Johanna received her MSc in Chemistry from Leipzig University, Germany. She carried out her thesis work in Prof. Eleanor Campbell’s group, University of Edinburgh, on Rydberg Fingerprint Spectroscopy of Endohedral Fullerenes. She stayed in Edinburgh for her doctoral studies in Laboratory Astrochemistry in the Group of Dr Ewen Campbell. She came to UCL in July 2023 and is using anion and liquid-microjet photoelectron spectroscopy to study biologically relevant molecular anions, and the effects of interactions between these molecular anions and their surroundings.

Outside work, she likes running and spending time in museums.

Nicholas Lau

3rd Year PhD Student

Nick obtained his MChem from the University of York in 2021, where he worked with Professor Caroline Dessent studying the gaseous geometries of charged phycocyanobilin and the scale mapping of their potential energy surfaces using computational chemistry. His PhD is co-funded by Photon Lines and is focussed on molecular beam photoelectron imaging and femtosecond transient absorption spectroscopy studies of atmospherically relevant molecules.

Outside work, he likes to bake, tinker with computers, and play badminton.

Kate Robertson

3rd Year PhD Student

Kate obtained her MPhys in Chemical Physics from Heriot-Watt University in 2021. For her final year project, she worked with Professor Dave Townsend investigating the photostability of different pigments found within paints. Her PhD is co-funded by Coherent and is focussed on femtosecond transient absorption spectroscopy and liquid-microjet photoelectron spectroscopy studies of biomolecules and their building blocks.

Outside work, she likes to run, go rock climbing, and play as a part of a brass band.

Edoardo Simonetti

2nd Year PhD Student

Edoardo obtained his MSci in Chemistry from UCL in 2022. He completed his final year research project in the Fielding group using liquid-microjet photoelectron spectroscopy to study the electronic structure of a protein chromophore in aqueous solution. His PhD is focussed on using photoelectron spectroscopy in liquid-microjets.

Outside work he enjoys embroidery and dancing.

Sufiyan Khan

2nd Year PhD Student

Sufiyan obtained his MSci in Physical Chemistry from Mumbai University in 2019. He completed his final year research project at Bhabha Atomic Research Centre (BARC) with Dr Sukhendu Nath and Dr Arun where he examined the bonding interactions and affinity of a DNA-fluorescent dye towards protein aggregates, using time-resolved fluorescence spectroscopy. His PhD is focussed on using femtosecond transient absorption spectroscopy of biomolecules.

Outside work, he enjoys cooking, gardening and spending time at the beach.
