Bachelor & Master research projects

At the moment we focus our activity on two fronts: 1) a measurement of the electron’s electric dipole moment using a gas of cold molecules, and 2) the use of optically levitated nanoparticles as very sensitive sensors. In addition to these two topics, there is also currently a project to accurately characterise arrays of nanopores using optical diffraction, in collaboration with a company that innovates dairy conservation methods. For our projects we typically work in teams consisting of one or two PhD students, master students and bachelor students.

The topic of the master projects is directly related to ongoing research, and I always aim to match the nature of the project to the interests of the student. Therefore, instead of mentioning specifics of projects here, I would encourage you to get in touch, so we can talk and see what research topic would fit you best. Then we can make sure that you learn a lot from your research project! We can typically tune the amount of theory, computer simulations and hands-on lab work. All projects have in common that you become an integral part of the research group, joining us in meetings, social activities, paper discussion, etc. In your research project you will learn the skills it takes to function well in such an environment.

To give you some specific ideas of possible topics, you can find titles of recent research projects in our group listed below.  If you want to know more, get in touch with me through email.
