This project is offered as part of the University of Dundee 4-year MRC DTP Programme “Quantitative and Interdisciplinary approaches to biomedical science”. This PhD programme brings together leading experts from the School of Life Sciences (SLS), the School of Medicine (SoM) and the School of Science and Engineering (SSE) to train the next generation of scientists at the forefront of international science. The outstanding biomedical research at the University of Dundee was recognised by its very high rankings in REF 2014, with Dundee rated as the top University for Biological Sciences in the UK. A wide range of projects are available within this programme crossing exceptional strengths in four key areas: Infection and Disease; Responses to Cellular Stresses; Development, Stem Cells and Neurobiology; and Big Data and Translation. All students on this programme will receive training in computational biology, mathematical biology and statistics to equip with the quantitative skills in tackling complex biological questions. In the 1st year, students will carry out 3 rotation projects prior to selection of the final PhD project.
To maintain their genetic integrity, eukaryotic cells must segregate their chromosomes properly to opposite spindle poles during mitosis. This process has important medical relevance because chromosome mis-segregation plays causative roles in human diseases such as cancers and congenital diseases. To prepare for proper chromosome segregation, kinetochores –the spindle attachment sites on chromosomes –must correctly interact with spindle microtubules (MTs) during early mitosis. It has been challenging to study these initial interactions because the dynamics of this process are complex, and the kinetochores and microtubules are densely packed and hard to distinguish. This research project will analyse these early kinetochore–MT interactions, in human cells, in far greater detail than has been achieved previously. To achieve this we will use a state-of-the-art Tri-SPIM light sheet microscope  that is capable of obtaining and analyzing fluorescent images of mitosis in live cells with high spatial and temporal resolution, excellent signal-to-noise and with minimal photo-damage to the dividing cells. These challenging imaging conditions are crucial to obtaining information about these vital and extremely dynamic early events in mitosis. The Tri-SPIM light sheet microscopy system has been recently implemented at our institute.This is the ideal system to fulfill the above imaging conditions. In this project, the student will use the Tri-SPIM microscope to analyze kinetochore–MT interaction in human cells, under the supervision of Tanaka and MacDonald. Tanaka is an expert in chromosome segregation and kinetochore–MT interaction , while MacDonald is an expert in light sheet imaging . Throughout this project, the student will learn basic and advanced techniques in cell and molecular biology as well as applications of state-of-the-art live-cell light sheet microscopy.
