Scientific Background

Research Interests

Molecular Machines

Stephen has researched the development and operation of molecular Brownian ratchet mechanisms. These allow the construction of molecular machines which can drive systems away from thermodynamic equilibrium. Stephen has demonstrated prototypical molecular machines formed of interlocked molecules, including catenanes and rotaxanes. He has focussed on chemically fuelled systems, which can operate using the energy released by the degradation of high energy chemicals to waste products.

Polymer Nanotechnology

Stephen’s research interests have recently branched into the use of polymers to construct functional nanotechnology. Stephen is currently exploring the use of amphiphilic block co-polymers to produce nanoparticles that react to different stimuli. Such dynamic behaviour will be used to control the outcome of chemical reactions.

Stephen has expertise in organic synthesis, NMR, mass spectrometry, electron microscopy and light scattering.

Scientific Inspiration

Scientific research is great, because (1) it is really interesting, (2) it is only limited by your creativity and (3) it benefits society. My inspiration is derived from making the impossible possible. For example, it would have been impossible to make the molecules in this project using knowledge from 10 years ago.

Research Groups

Fielden Group

Supervision Style

In three words or phrases: understanding, goal-driven, inclusive.

Provision of Training

I pursued research in my career that his given me a unique skillset. Now it’s time for me to train others, so we can build a new research programme together. Therefore, I will personally train you in new scientific techniques, as well as in skills such as report writing and presenting. I will be closely involved in your project at the start of your PhD and will allow you to be more independent as you gain more experience. Learning to direct your own research is a key skill gained during a PhD.

Progression Monitoring and Management

Similar to the training strategy, I will initially closely manage your progression. This is because research is difficult and you will need help transitioning from taught education. As you gain skills in time-management and planning, I will allow you to determine your own schedule. As I am a new academic, joining my group is an investment for both of us, so I will encourage and help you to reach your full potential.

Communication

I am known to email my team at all hours of the day and night, however I will not expect you to do the same. I am here to support you scientifically and pastorally, so am happy to discuss issues when they arise.

PhD Students can expect scheduled meetings with me:

In a group meeting

At least once per fortnight

In year 1 of PhD study

At least once per fortnight

In year 2 of PhD study

At least once per month

In year 3 of PhD study

At least once per month

These meetings will be face to face. I have an open door policy, though my pattern of being contactable for instant response is not predictable.

Work Patterns

Certain tasks in my lab need to occur at set times, and students need to be able to commit to a rota/timetable shared with other members of the team.

Notice Period for Feedback

I need at least 2 weeks' notice to provide feedback on written work of up to 5000 words.
