Personal profile
Research
My research concerns extremal polynomials in the complex plane. I'm specifically interested in studying how the geometry of a set influences the behaviour of the associated Chebyshev polynomials. Examples on this is how the zeros and maximum values of these behave as the degree of the polynomial tends to infinity.
My PhD-supervisor is Jacob Stordal Christiansen.
