My research is in logic and model theory. More precisely my research interests are:

- Model theory of nilpotent groups and Lie algebras.
- Tame expansions of the group of integers in the NIP side (p-adic valuations, predicates.
- dp-rank and algebra: classification of dp-minimal integral domains; example of dp-finite division algebras.
- generic expansions and the preservation of Shelah's tameness properties, such as NTP2, NSOP1, NIP, etc.
- expansions of fields by generic structures:
- predicates: for subgroups, for subfields. Such expansions can be new examples of NSOP1 theories.
- homomorphism: maps that preserves the multiplicative structure of a field, a new NSOP1 not simple theory.

- Positive logic and expansions by predicates.

- Model-theoretic properties of nilpotent groups and Lie algebras (joint with Isabel Müller, Nick Ramsey and Daoud Siniora): We prove that the class of c-nilpotent Lie algebras over an arbitrary field, in a language with predicates for a Lazard series, is closed under free amalgamation. We show that for c>2, the theory obtained is strictly NSOP4 and c-dependent. For c=2 the theory is NSOP1. Via the Lazard correspondence, we obtain the same result for c-nilpotent groups of exponent p, for an odd prime p>c. (Journal of Algebra, 2024)
- Existentially closed models of fields with a distinguished submodule (joint with Leor Neuhauser and Itay Kaplan): We study the category of existentially closed models of fields with a distinguished submodule, in the Robinson setting. We prove that this category is NSOP1 and TP2 in the positive sense. (To appear in Journal of Symbolic Logic).
- On algebraically closed fields with a distinguished subfield (joint with Leor Neuhauser and Itay Kaplan): We study the model theory of pairs (K,F) where K is algebraically closed and F is arbitrary with extra structure. We prove that tameness properties of F are preserved in the expansion (K,F). In particular we deduce that a PAC field F is NSOP1 if and only if its absolute Galois group is NSOP1 as a profinite group. (Israel Journal of Mathematics, 2024).
- Vector spaces with a dense-codense generic submodule (joint with Alex Berenstein, Yevgeniy Vasilyev): We study generic expansions of a vector space V over a field F with a submodule over a subring of F, satifying some Mordell-Lang condition. This expansions preserve tame model-theoretic properties such as stability, NIP, NTP1, NTP2 and NSOP1. (Annals of Pure and Applied Logic, 2024).
- Enriching a predicate and tame expansions of the integers (joint with Gabriel Conant, Yatir Halevi, Léo Jimenez , Silvain Rideau-Kikuchi): We study the expansion of a theory by enriching the induced structure of a stably embedded in particular, we prove preservation of combinatorial tameness properties, such as stability, simplicity, NSOP1, NIP, NTP2. We use those results to answer several open questions on tame expansions of the integers. (Journal of Mathematical Logic, 2023). (Oddity: an AI-generated podcast of this paper was implemented by Yatir Halevi and is available here).
- Dp-minimal integral domains (joint work with Yatir Halevi): A classification of dp-minimal integral domains, very closed to be valuation rings, all of them are divided domains (every prime ideal is comparable to any principal ideal). (Israel Journal of Mathematics, 2021).
- Forking, Imaginaries and other features of ACFG: A study of the generic theory of algebraically closed fields of positive characteristic
with a predicate for an additive subgroup. (Journal of Symbolic Logic, 2021)
- Generic expansion of an abelian variety by a subgroup: The theory of an abelian variety expanded by a predicate for a divisible subgroup with the same torsion admits a model companion. The resulting theory is NSOP1 and not simple. (Mathematical Logic Quarterly, 2021)
- Generic expansion by a reduct: Expanding a theory by a generic predicate for a reduct of the theory. This generalisation of belle paires and of generic predicate preserves NSOP1. (Journal of Mathematical Logic, 2021)
- A new dp-minimal expansion of the integers (joint with Eran Alouf): The expansion of the group of integers by a p-adic valuation is dp-minimal. (Journal of Symbolic Logic, 2019).

- A two-sorted theory of nilpotent Lie algebras (joint with Isabel Müller, Nick Ramsey and Daoud Siniora): We describe a two-sorted theory of generic nilpotent Lie algebra of fixed nilpotency class with a separate sort for the field. We prove relative quantifier elimination up to the field sort and prove that if the field is NSOP1 then the Lie algebra is NSOP4, using a new criterion using a (not necessary stationary) independence relation.
- The classification of dp-minimal integral domains (joint with Yatir Halevi and Will Johnson): We classify dp-minimal integral domains, building off the existing classification of dp-minimal fields and dp-minimal valuation rings. We show that if R is a dp-minimal integral domain, then R is a field or a valuation ring or arises from the following construction: there is a dp-minimal valuation overring O extending R, a proper ideal I in O, and a finite subring S in O/I such that R is the preimage of S in O.
- Generic multiplicative endomorphism of a field: We study generic expansions of a field by a generic endomorphism of the multiplicative group. We show that the resulting theory is NSOP1 and not simple, eliminates imaginaries under the existence axiom and that the kernel of the endomorphism is pseudofinite-cyclic as a pure group.
- Cyclic and non-cyclic division algebras of finite dp-rank: We give examples of cyclic divisions algebras of finite dp-rank, answering a question of Milliet. We also give an example of an IP cyclic division algbra of finite burden and a non-cyclic division algebra of dp-rank 16.
