About me
I am currently a postdoctoral fellow at the AHEP group, which belongs to Instituto de Física Corpuscular, in Valencia. I did my Ph.D. at CFTP, a research center of Instituto Superior Técnico, in Lisbon, under the supervision of Jorge C. Romão and Ana M. Teixeira.
I have worked on the following areas:
- Grand unified theories and group theory for model building
- Flavour symmetries
- Neutrino mass and neutrinoless double beta decay models
- Phenomenology of supersymmetric models
- Lepton flavor violation
- Computation of renormalization group equations

Academic programs
- Susyno
Susyno is a Mathematica package which calculates the 2-loop
renormalisation group equations of supersymmetric models, based
on any gauge group and
with any field content. To accomplish this, Susyno contains several group theoretical functions which may be useful on their own. For example, it can calculate the dimension, the Casimir or even the explicit matrices in some basis of a Lie group representation (various examples can be found here ).
- Sym2Int
Sym2Int is a Mathematica package which lists all valid interactions given a model's gauge group and fields. The fields are specified by their gauge and Lorentz transformation properties.
Non-academic things
- The Mandelbrot set
The Mandelbrot set is a famous mathematical object which gives nice pictures and is very easy to code. This page contains a small Javascript program which I created just for fun, and there is also a laid-back discussion of some basic features of this curious object (note: if you can, use Google Chrome to view this page, because it runs Javascript faster).
