My primary research interest lies in the
domain of *Microeconomics* and, specifically, the fields of
*Mechanism Design, Optimal Taxation, *and *Market Design*.
In mechanism design, my work focuses on robust mechanisms,
i.e., mechanisms that are not sensitive to the fine details of
the environment. In particular,
**[2]** shows that in standard social choice environments with private types Bayesian incentive compatibility
(BIC) is equivalent to dominant strategy incentive compatibility
(DIC). Subsequent papers (**[6]**
and ** [7]**) extend this result
to environments with correlated types and non-linear utilities. In
conjunction with the BIC-DIC equivalence, **[8]**
analyzes also a purely mathematical question when a transformation of closed sets coincides with the intersection of their
images.

My research also
studies incentive compatibility constraints—the crucial constraints
in mechanism design that ensure that agents communicate their
privately held information truthfully. Paper **[9]** simplifies incentive compatibility
constraints in often complex multi-dimensional environments. My
another paper **[3]** develops a novel geometric approach to mechanism design that exploits classical results from convex analysis and majorization theory to provide a tractable analysis of generally complex resource and incentive constraints.
A subsequent paper
**[4]** extends the geometric approach
to environments with interdependent values.

My
research in optimal taxation (**[11]**) studies income taxation policy in the
presence of non-competitive markets. It develops a theoretical
analysis of the optimal income tax schedule in the presence of
endogenous prices and takes it to the data.

My work in the area of market design focuses on the analysis of signaling mechanisms
in some labor markets and online dating platforms. This endeavor shows that the introduction of private signals facilitates match formation for a wide range of environments (**[1]**). Nevertheless, there are instances when signaling precludes match formation (**[5]**).

I am also involved in a project related to *Network Theory*
that studies information-posting technologies in social platforms**[10]**).
