Physics/Expert Profile
Expertise
I will try to answer any question in physics, but I do not provide homework solutions or project ideas. I have some teaching experience at university level but I am also skilled at explaining things in simple terms. My specialty areas are granular materials, computational physics, particle physics, quantum physics, econophysics and general physics. Questions in GERMAN are welcome, too.
Experience in the area
I have graduated in physics, specialized in theoretical particle physics and quantum field theory, worked in the area of econophysics and am currently working on my PhD in granular materials and computational physics. I have some tutoring and teaching experience at University level.
Education/Credentials
German Diploma in Physics (equivalent to M.Sc)
