My name is Julian Gosliga. From a young age, I was interested in science, and as I grew older I started to become interested in machinery and cars especially. And so, after completing my A-levels, I moved to Sheffield to study Mechanical Engineering. It was during this time I realised that research was where I wanted to be, so naturally I decided to stay on to do postgraduate research within the department. Outside of my academic work, my interests include snowboarding, climbing and playing bass guitar. Sheffield is great for both the music and climbing, unfortunately since the loss of the ski-village there is less snowboarding. My other passion is Star Wars, how many other Western space-operas can claim so many box-office record-breakers?
Research interests
I am interested in researching the coupled physics of transducers in the context of improving the efficiency of energy harvesters. Examining the underlying physics of systems in an engineering context. Looking at the behaviour of smart materials so that they can be utilised more efficiently.
Current research
Vibrational harvesters of all sorts have been extensively studied and optimised, there is a limit to how much energy they can ever harvest (deterministic and stochastic limit). It would seem that not much more performance can be gained from these harvesters alone. Therefore, it would seem logical to try and combine harvesting from other energy sources to increase the total harvested. My current research is focusing on developing expressions for the possible amount of energy that can be harvested from a particular source. This requires an understanding of how much is available and how much the system can possibly capture. By examining the coupled equations for the systems, I can examine how the energy is transferred between them.

These are some of the more artistic plots, a complimentary colour choice can make the output from a stochastically driven non-linear system look quite extraordinary. The left image shows outputs from systems with varying parameters, the right image shows similar systems when ensemble averaged over a small series of simulations.
My research now involves looking for the relationship between inputs from different energy sources, and so the power from a given source can be determined by a coupling coefficient. Some relationship is evident from numerical simulations.
