My primary research interest lies in the domain of Mechanism
and Market Design. My contribution to
mechanism design includes the analysis of fundamental questions of
implementation. 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],
[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 projection of
two convex closed sets coincides with the intersection of their
images.

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 work on market design focuses on the analysis of a signaling mechanism in two-sided matching markets. 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 projects related to the theory of networks (**[9]**)
and optimal income taxation (**[10]**).
