 Machine learning has impacted many scientific fields, and particle physics is no exception. ​ In my research, I aim to enhance the search for new phenomena at colliders by merging the performance of deep learning algorithms with the robustness of "deep thinking"​ approaches. Machine learning has impacted many scientific fields, and particle physics is no exception. ​ In my research, I aim to enhance the search for new phenomena at colliders by merging the performance of deep learning algorithms with the robustness of "deep thinking"​ approaches.

 Jets are collimated sprays of particles arising from the fragmentation of short-distance quarks and gluons. ​ In traditional collider studies, these jets are reconstructed using jet algorithms, which assign clusters of particles to jet four-vectors. ​ I have shown that the substructure of jets can provide valuable information about the underlying short-distance physics. ​ In extreme cases, physics that would otherwise be unobservable using traditional jet algorithms can be made prominent through jet substructure techniques. Jets are collimated sprays of particles arising from the fragmentation of short-distance quarks and gluons. ​ In traditional collider studies, these jets are reconstructed using jet algorithms, which assign clusters of particles to jet four-vectors. ​ I have shown that the substructure of jets can provide valuable information about the underlying short-distance physics. ​ In extreme cases, physics that would otherwise be unobservable using traditional jet algorithms can be made prominent through jet substructure techniques.

 Dark forces are part of a large paradigm of dark portals connecting visible and hidden sectors of nature. ​ I developed the idea of an "axion portal",​ where dark matter and ordinary matter interact via a light pseudoscalar particle. ​ While dark matter itself is quite difficult to probe in these scenarios, the axion leaves distinction signatures in collider experiments. ​ Axion-like states and stable dark matter arise quite generically in supersymmetric hidden sectors, which can have an interesting effect on the measured cosmic ray spectrum. Dark forces are part of a large paradigm of dark portals connecting visible and hidden sectors of nature. ​ I developed the idea of an "axion portal",​ where dark matter and ordinary matter interact via a light pseudoscalar particle. ​ While dark matter itself is quite difficult to probe in these scenarios, the axion leaves distinction signatures in collider experiments. ​ Axion-like states and stable dark matter arise quite generically in supersymmetric hidden sectors, which can have an interesting effect on the measured cosmic ray spectrum.
