My Vision

"My primary goal is to shorten the bridge between theory and observations in Cosmology."

 

My strategies: 

1. Accurate predictions of observables matching the accuracy level of the upcoming galaxy surveys. Examples of this are my PhD work on Effective Field Theory of Large Scale structure and my work on lensing and unequal-time correlators during my first postdoc at the University of Manchester.
2. Open-source software: science should be open, completely accessible and easily reproducible. Examples of this are my contributions and authorship in a variety of high-quality open-source software:  SkyPyunequalpy and corfu.
3. Team work: fostering collaborations and respectful team dynamics, internationally and at my place of work. Currently, I am a coordinatior of the SkyPy collaboration and Validation Lead of the Spectroscopy Visibility Mask of the Euclid Science Ground Segment.
4. Leadership skills developed through my own collaborations: EFTpy with an international team of experts in Dark Energy, and QGTpy connecting quantum thermometry and cosmological observations.


My track records

 

My beginning. 

As a BSc student in Madrid, I worked on Quantum Cosmology with Dr Mena at CSIC and published my first paper in international journals.

 

As an MSc at the University of Aix-Marseille, I worked "f(R) theories of gravity" supervised by Dr. Marinoni. I explored the "Effective Field Theories of Dark Energy" supervised by Heinrich Steigerwald and Dr. Marinoni (CPT), and I learned to use Interactive Data Language. I also studied the phenomenological side of the "Effective Field Theories of Dark Energy" under the supervision of Dr Álvaro de la Cruz Dombriz (UCM),  completing  my master's thesis.

 

My PhD. 

As a PhD student at the University of Sussex, I worked on Effective Field Theory of Large-Scale Structure. I explored higher-order perturbation theory techniques, correctly describing redshift-space distortions and baryon acoustic oscillations. I used novel techniques to reduce the tensor part of the integrals, and obtained, for the first time in cosmology, the full time-dependence of all non-linear growth functions. I applied these methods to different halo bias and redshift models, developing the most general bias and using simulations. This work resulted in my two most-cited publications, presentation in international conferences, and passing my viva with merits.

 

First postdoc position. 

As a postdoc at the University of Manchester, I became immersed in the work of the group, became a member of DES and transitioned from theoretical to observational cosmology. I identified a theoretical problem leading to biased predictions of cosmological parameters for upcoming galaxy surveys. I studied the inaccuracy of different approximations to the angular power spectra, provided a method for the exact calculation, and computed the one-loop unequal-time power spectrum. I analysed the impact on cosmic shear, galaxy clustering and galaxy-galaxy lensing with future application to redshift-space distortions. Result of this is a series of two upcoming publications and two python packages.

 

As a co-founder of SkyPy, I led contributions to the galaxy and halo modules. I developed strong computational skills in Python, GitHub, high-standard coding and peer-review habits. I fostered my communication, leadership and teamwork skills as a leading contributor of the halo team, funding and meeting co-organiser.

 

I am an experienced Associate Fellow and Secondary School Qualified Teacher. I organised a series of lectures for other PhD students.
