Welcome to my personal homepage. This is where I intend to gather relevant information about my professional life (as well as some fun stuff).

I am a theoretical physicist. The topics of my research are concerned with gravity and high energy physics. Currently I am most interested in theoretical aspects of black hole physics.

I received my PhD in Physics from University of California, Santa Barbara in 2008 under the supervision of Prof. Joseph Polchinski. Currently, I am a post-doc at CENTRA / Instituto Superior Técnico working with Dr. Vitor Cardoso.

I hope you find the information contained in this webpage useful. Happy navigation!


Research Interests

I have a broad range of interests. My research topics over the past years include cosmic strings, information paradox, gauge/gravity dualities, fluid lump solutions dual to black holes, integrability in (super)gravity and cosmic censorship. (Click on each topic to expand/collapse.)

Cosmic strings

Information paradox and the AdS/CFT correspondence

Lobed plasma balls and the fluid-gravity correspondence

Integrability of 5D minimal supergravity

Higher dimensional black holes and cosmic censorship

Constructing dipole black rings

High energy collisions in gravitational duals of confining gauge theories
