I have joined the Costantini group in September 2013. My current research is primarily focused on hte imaging of conjugated polymers using combined electrospray deposition coupled with a scanning tunnelling microscope.
Previous in the same group I worked on the European Research Council funded Visual-MS project. Myself and Dan Warr developed a compact electrospray ionisation deposition system capable of depositing large and/or fragile molecules (e.g. peptides) onto surfaces. After deposition, the shape, assembly and conformation of these molecules can be studied using a ultra-high vacuum scanning tunnelling microscope. This deposition system is capable of mass selection/spectroscopy and controlling the impact energy of the deposited molecular ions.
I also have research-driven interest in the development of software tools for rapid data analysis. Please find some notable examples in my Sourceforge page. In particular I developed a very useful tool called LMAPper. This program allows the user to manipulate scaled 3D molecular models in perfect harmony with STM images.
My current scientific interests include atomic-scale imaging of molecules, graphene, scientific instruments, software development and electronics.
I have previously been involved in notable studies of molecules on surfaces during my appointment at the University of Nottingham. There, I used ultra-high vacuum, room temperature scanning tunnelling microscopy extensively. I utilised both electrospray and conventional thermal sublimation for molecular deposition. Examples of molecular systems I have studied include porphyrin nanorings, self-assembly of supramolecular hydrogen-bonded networks, graphene formation on nickel thin films, molecular cages and tweezers and silicon surfaces.
Outside of work I enjoy orienteering. Despite being quite bad at it and slow, I enjoy the fun of it. I occasionally compete and complete (with great difficulty), half marathons. I am well known for often provoking others by claiming that I will beat them in races, however I end up always losing, a kind of reverse impostor syndrome. I am probably much better in science though, for some reason, I don't boast that as much as I probably should.
