Miguel Ruiz-Granda

I am a PhD student specializing in observational cosmology, funded by the FPU grant from the Spanish Ministry of Science, Innovation, and Universities. I hold Bachelor’s degrees in both Physics and Mathematics from the University of Cantabria. During my final undergraduate projects, I focused on the Cosmic Microwave Background (CMB) and applied optimization techniques to industrial processes. My Master’s research introduced me to CMB weak lensing, specifically working with data from Planck and preparing for the upcoming LiteBIRD space mission.

Since beginning my PhD in January 2023, under the supervision of Patricio Vielva and Diego Herranz, I have continued my research on CMB lensing within the LiteBIRD collaboration and expanded my focus to include foreground removal for 21 cm Line Intensity Mapping (LIM).

My research interests cover a wide range of cosmological topics. As a physics undergraduate, I explored the accuracy of CMB physical processes modeling and its potential impact on cosmological tensions, such as the Hubble constant. During my Master’s, I shifted toward studying CMB weak lensing, which examines how gravitational fields subtly affect the path of CMB photons. I am continuing this work in my PhD, investigating how combining Planck and LiteBIRD data can enhance the signal-to-noise ratio of lensing detection. Expanding into 21 cm LIM, I participated in the SKA Data Challenge 3a, focusing on removing foreground contaminants to retrieve the 21 cm Epoch of Reionization signal. I am now building on this by working on foreground removal techniques for low-redshift observations.
