Re: MSc. Jacob Hamfeldt Kold

MSc. Jacob Hamfeldt Kold has had position as a Bachelor in our laboratory at the Niels Bohr lnstitutethat lasted for several monthS. During this period I was the supervisor of his master project oncollision of action potentials in nerves. Hence, I had the opportunity to follow his work along thatperiod.

His work in our laboratory has certainly exceeded even our expectations and he has performed anumber of electrophysiology studies of the highest quality using Lumbricus terrestris. His preliminarywork as a bachelor student resulted in further experiments that where published in Physical review Xin 2014. He has demonstrated a profound knowledge of membrane biophysics and their relation withneuroscience. Also, he plans his work very systematically and runs experiments efficiently. He is verygood to work with and he interacts very well with other group members. Because he is a verycomponent researcher, it is without reservation that I give him my best recommendations. Certainlyhe will be a valuable asset in any research team looking for an optimal PhD student,
