Professor Kishan Dholakia (FRSE, OSA Fellow, SPIE Fellow) is a professor in the Department of Physics & Astronomy. He has worked for a number of years as a postdoctoral research fellow, a Royal Society of Edinburgh Research Fellow, and now as a permanent member of staff. His research interests cover pretty much everything related to optics.
Yoshi Arita is a research fellow whose primary focus of study is on levitated optomechanics with structured light. He completed a DPhil in atomic and laser physics with a thesis entitled “Multi-mode absorption spectroscopy” in the Paul Ewart group at University of Oxford. He moved to St Andrews to pursue his postdoctoral research, including laser transfection, digital holographic microscopy and micromanipulation both in liquid, air and vacuum. He became a research associate professor (part-time) at Chiba University in Japan since October 2015, directing a new research strand, photopolymerisation with structured light.

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.
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.
Saba N. Khan is a research fellow working on optical manipulation with structured light and Laser speckle metrology. Before joining University of St Andrews, she was a Postdoctoral fellow in Department of Physics, Indian Institute of Technology Delhi, India where she was working on polarization singular beams. She received her PhD from Indian Institute of Technology Kharagpur, West Bengal, India, working on few-mode fiber sensors. Her previous education includes a Bachelor’s degree in Physics & Mathematics from Lucknow University and Master’s degree in Physics from Indian Institute of Technology Delhi, India.
Manuel graduated from INAOE in Mexico. His Masters project consisted on new applications of non-diffracting beams for optical trapping by implementing the optical tweezers toolbox and the use of beam shaping techniques at The University of Queensland, Australia. His joined the Optical Manipulation Group to pursue his PhD Project in micromanipulation in liquid, air and vacuum.
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.
Josephine Morizet is a postdoctoral research fellow working on the development of new light sheet microscope modalities dedicated to biological applications. She graduated in optical engineering from the Institute of Optics at the University of Paris-Saclay in 2016, then she completed her PhD at the Laboratory of Optics and Biosciences (Ecole Polytechnique, France) where she investigated the potential of polarisation-resolved THG microscopy to probe biomaterials structure.
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.
