I am physicist by training with strong interest in the physical functioning of biological systems. My research at the interface of physics, biology, and immunology combines theoretical and experimental concepts to study the impact of a vital cytoskeleton in immunity. Having had a steep transition from theoretical physics to cell bio-immunity, my research aims to join state of art imaging modes and computation analysis methods to address important biomedical research questions from a bio-physical perspective: We are taking highly interdisciplinary approaches to investigate cytoskeleton-driven cellular processes in immunity and disease.

Kseniya Korobchevskaya, PhD
Microscopy Staff Scientist Email: Kseniya.Korobchevskaya@kennedy.ox.ac.uk
Having a strong background in experimental physics and optics, I was always interested in biological applications. For that reason, after completing my PhD in ultrafast spectroscopy I moved to the field of super-resolution microscopy. As a part of the Nanoscopy group at IIT I worked on the development of label-free near IR pump-probe nanoscope. Besides, I was also closely involved in other projects related to nonlinear microscopy, such as subtraction microscopy approaches for second-harmonic generation imaging of collagen fibres or two-photon spectrofluorimetric characterization of a new set of red-emitting proteins.
Presently, I am working on the development of eTIRF-SIM microscopy at KIR for investigating the cytoskeleton dynamical response in live cells. My main research interests lie in super-resolution microscopy, nonlinear optics, and ultrafast laser spectroscopy.

The role of mechanical force has gained increasing interest in the field of cell biology. This has come from the realisation that cells are continually subject to stresses and strains induced by the cellular environment. Cells are known to be able to sense and react to forces imposed on them by their local environment as well as being able to directly impart force during motility and adhesion. This is also true for cells of the immune system, specifically, T-cells are known to be highly motile, navigating through the blood, tissue and lymphatic system. To achieve this level of mobility, T-cells rely on a highly dynamic cytoskeleton. On encountering an Antigen Presenting Cell (APC) that is presenting a foreign antigen, T-cells become activated. This highly selective process by which a T-cell is able to bind, recognise and react to only foreign antigens has been the focus of intense study due to its crucial importance in the adaptive immune response. Despite this, the early stages of T-cell activation remain unclear. The possible active role mechanical force might play in this process has been largely overlooked and a quantitative approach to measuring the forces generated during this interaction is lacking. By employing tools from biophysics and cell mechanics the work proposed aims to investigate the possible role of mechanical force in the initiation and continuation of the T-cell-APC interaction.

I am a physicist by training with strong interest in understanding the physical principles of cell-biological systems. Currently, I am working on the characterisation of the reorganisation dynamics of the cortical actin cytoskeleton during T-cell activation. Cortical actin dynamics give rise to active force production, which I quantify by simultaneous read-out of the mechanical forces and the underlying turnover dynamics of actin and key proteins involved in the activation process such as the T-cell receptor. Understanding the role of the actin cytoskeleton is now becoming a contentious questions in immunology but progress has previously been limited, mainly due to the use of conventional-resolution microscopy, which inevitably misses essential details due to limited resolution. To overcome these limitations, I will work with more advanced microscopy techniques, such as super-resolution optical nanoscopy combined with traction force microscopy and atomic force microscopy.

I have a strong background in molecular medicine and am currently undertaking the MSc in Integrated Immunology at the University of Oxford. Over the years, I have become fascinated with T cells and their activation and signalling. In my project, I am investigating the early effects of T cell activation and calcium signalling using confocal spinning disk microscopy.

Angela Lee, MSc
I am an immunologist by training with strong interest in adaptive immune responses. My research focused on the early signalling events during T-cell activation. Employing biochemistry, biophysics, and high-NA confocal microscopy, I investigate the relationship between calcium early signalling events of T cells and subsequent actin cytoskeleton reorganisations.

I performed my MSc. in Integrated Immunology at the University of Oxford. Using advanced imaging modalities (Airyscan and TIRF), I investiged the formation of immunological synapse in mast cells. Specifically, my project focuses on calcium's impact on the dynamics of the cortical actin cytoskeleton. Currently, I am pursuing a Bachelor degree in law at the University of California Davis.
Mark Skamrahl, BSc
Master Student Email: firstname.lastname@example.org
In my research project, I combined AFM (Atomic Force Microscopy) and FRAP (Fluorescence Recovery After Photobleaching) to investigate the direct interplay of actin turnover dynamics and cellular mechanics. I performed this study as part of my Master's degree in Biochemistry and Biophysics at the University of Freiburg, Germany. Currently, I am pursuing a PhD in Professor Janshoff's lab at the University of Goettingen.
