Graham Bruce is a senior researcher and laboratory manager in the group. He graduated from University of St Andrews with an MPhys degree in Theoretical Physics and Mathematics and remained in St Andrews to complete a PhD in ultracold atoms and the generation of novel optical trapping geometries. His postdoctoral research was carried out at University of Strathclyde, constructing the world’s first quantum gas microscope for fermionic atoms, and back in St Andrews developing cold-atom rotation sensors. He joined the Optical Manipulation group as a research fellow, and has diversified his research interests to work on optical trapping and cooling in vacuum, speckle metrology and Raman spectroscopy.

Mingzhou Chen is a senior research fellow whose whose research interests include multiphoton tissue imaging, Raman spectroscopy, OCT, optical vortices, beam shaping and complex optical wave fields. He obtained a master degree from Tianjin University (China). After a period working in industry, he completed his PhD at University of Pretoria (South Africa) under supervision of Professor S. Roux. He has also worked with Professor Chris Dainty as a postdoctoral researcher at the Applied Optics Group in National University of Ireland Galway (Ireland).
Stella Corsetti joined the Optical Manipulation Group as a Postdoctoral Research Fellow in February 2018. Her research includes the use of advanced optical and imaging techniques for biomedical applications and medical diagnostics. She obtained her BSc in Biomedical Engineering and her MSc in Bio-Nanotechnology Engineering from the University of Rome ‘La Sapienza’, and her PhD in Chemical Engineering from the University of Aberdeen. Her project involved the use of single particle manipulation techniques and Raman and Infrared spectroscopy to study hydrocarbon phase transitions. She then became a PDRA exploring the applications of Raman spectroscopy and surface enhanced Raman spectroscopy (SERS) in drug discovery and medical diagnostics.
Nicolas Dubost joined the Optical Manipulation Group as a Postdoctoral Research Fellow in 2020, after completing a PhD at Durham University. During this time, he worked on point-diffraction interferometry for wavefront sensing in astronomical adaptive optics. His current research involves the use and development of light-sheet microscopy for biomedical applications.

George Okyere Dwapanyin joined the group as a research fellow in January 2021 with research focusing on advanced optical imaging techniques. He has a PhD from Stellenbosch University, South Africa where his dissertation focused on the development of a multimodal imaging system for Biophotonics applications. His previous education includes a BSc in Physics from the University of Cape Coast, Ghana, MSc in Optics and Photonics from Karlsruhe Institute of Technology, Germany, and MSc in Photonics Engineering, Nanophotonics and Biophotonics from the Universitat Politècnica de Catalunya, Spain after having being part of the pioneering batch of the Erasmus Mundus Europhotonics master program.
Morgan Facchin obtained a Bachelor’s degree in physics from the University of Avignon, and a Master’s degree in astrophysics from the University of Toulouse. In 2017 and 2018 he worked on phase singularities and superoscillations in solar waves. Then he joined the Optical Manipulation group in 2019 to work on new ways of harnessing laser speckle patterns for high accuracy measurements, as well as optical manipulation.
Roopam Gupta is a final year PhD student in the group. He graduated from Indian Institute of Science Education and Research Kolkata with an integrated BS-MS degree in Physical sciences. During his masters, Roopam worked in experimental condensed matter physics and focussed on studying the “Magneto-optical Kerr effect in correlated optical systems”; more specifically – he studied the effects of magnetic field on bi-layer structures of metallic and topological insulator materials. His PhD focuses on the applications of machine learning for the development of label-free optical hemograms of immune cells by using spectroscopic and imaging modalities and for the development of speckle based wavemeters and spectrometers.
Lewis McMillan joined the group in October 2020 as a postdoctoral research fellow in Computational Methods for Image Analysis in Biophotonics. He obtained his PhD in computational physics from the University of St Andrews which focussed on using the Monte Carlo method to simulate the transport of light in tissue for various biophotonic and medical applications. Lewis was previously a research fellow in Computer Science and Astrophysics at the University of St Andrews where he used machine learning to classify images of dolphins from drone videos, and optimised galaxy image analysis codes. His interests lie in using code to solve various research problems in the fields of marine biology, biophotonics, medicine, and physics.
Persephone graduated from the University of St Andrews where her Masters project involved creating a computational model of Optical Coherence Tomography using Monte Carlo techniques. Her PhD research builds on advanced microscopy methods (including SIM and Light-Sheet Microscopy) for applications in histopathology.
Georgina Shillito obtained a PhD in chemistry from the University of Otago, New Zealand in 2019 and specialises in Raman spectroscopy. Her PhD involved investigation of charge transfer states in transition metal complexes, which displayed potential to function as molecular sensors or light-harvesting solar dyes. Her research has involved the use of various vibrational and electronic spectroscopic techniques, as well some computational chemistry methods. As part of the Optical Manipulation group, she will be utilising Raman spectroscopy to study a range of samples in complex media.
Philip Wijesinghe joined the group as a Research Fellow in 2018, with a focus on merging theory, computational and numerical methods towards imaging in biophotonics and biophysics. In particular, he works in light-sheet and multiphoton microscopy, with a focus on computational imaging via multiplexing, sparce sensing and recovery, and deep learning. Previously, he was a Research Associate in the Harry Perkins Institute of Medical Research and a PhD Student in the Optical+Biomedical Engineering Laboratory (OBEL) in the University of Western Australia. There his work focused on the development of optical coherence tomography-based methods to image the mechanical properties of tissues and cells towards applications in cell mechanobiology, cardiology and oncology.
