First-order theory of a field and its Inverse Galois Problem [PDF]
Let $G$ be a finite group. Then there exists a first-order statement $S(G)$ in the language of rings without parameters and depending only on $G$ such that, for any field $K$, we have that $K\models S(G)$ if and only if $K$ has a Galois extension with the Galois group isomorphic to $G$.

Abelian constraints in inverse Galois theory [PDF]
Let \(k\) be a field, \(B\) a \(k\)-curve (i.e. a smooth projective and geometrically connected \(k\)-scheme of dimension 1), \(G\) a finite group, \(f:Y\to B\) a \(k\)-\(G\)-cover of curves with group \(G\) and ramification indices \(e_1,\dots,e_r\) and let \(P\) be ant subgroup of \(G\) of index \(m.\) Assume that the branch divisor of \(f:Y\to B ...

Commutative and noncommutative aspects of inverse Galois theory
In this thesis, we are dealing with both commutative and noncommutative aspects of inverse Galois theory. In the commutative setting, we produce explicit Galois realizations of some infinite families of 2-groups. In the non-commutative setting, we study the inverse Galois problem and finite embedding problems over some twisted skew fields of fractions.
