About me

Welcome to my world, where science and art converge. My name is Julia Bauzá-Martinez, I am a doctor in Biomolecular Mass Spectrometry by formation, and I have always been passionate about understanding the complexity of multicellular organisms from a molecular biology perspective. Moreover, as the daughter of an artist, I've nurtured a lifelong passion for drawing, from realistic portraits to invented characters. Alongside my artistic pursuits, I also find joy in playing music, crafting jewelry, and exploring various forms of artistic expression. 

During my doctoral studies, I discovered and developed my talent for scientific illustration, transforming complex data into visually captivating graphs that not only aided my colleagues but also contributed to impactful publications. With this passion in mind, and knowing that I thrive on the opportunity to work on a variety of topics rather than focusing on a single one, I decided to pursue my dream career project — Skid Visual Science. Combining efficiency and dedication, I merge the precision of science with the allure of art. Let's collaborate to bring your ideas to life through eye-catching figures and illustrations that foster a deep understanding of your topic and engage your audience. Together, we can create something truly remarkable.


2018 - 2022

PhD in Biomolecular mass spectrometry
Utrecht University
Promotor: Albert J.R. Heck

Co-promotor: Wei Wu

During my PhD, I became proficient in operating and troubleshooting various mass spectrometers (Orbitrap HF, Fusion, Lumos, etc.), HPLC systems (1290, Ultimate 3000), and I specialized in various mass-spectrometric techniques (proteomics, phosphoproteomics, peptidomics, etc.). I continued to develop my skills in data analysis softwares (MaxQuant, Proteome Discoverer, etc.), as well as in analytical techniques, powered by my passion in R programming. I also adquired advanced skills in Adobe Illustrator for scientific illustration.

2016 - 2017

MSc in Biomedical Research
Pompeu Fabra University 

During my MSc in Biomedical Research internship, I gained valuable experience in human blood plasma sample preparation and MS data analysis, focusing on studying proteolysis dysregulation in shock and sepsis within the ShockOmics project. I worked with LC-MS instruments, performed proteomics sample preparation techniques, and developed skills in data analysis software, techniques and programming. 

2012 - 2016

BSc in Biotechnology
Vic University

During my BSc in Biotechnology, I gained practical experience through various internships. At the Molecular Biology department of Vic University, I performed techniques such as PCR and DNA extraction. In the Microbiology Area of Ibiza’s hospital, I conducted bacterial culture and identification, along with serological analysis. At Bioingenium, I worked with bacterial and yeast cell culture, protein production, and purification. Lastly, at the Proteomics Platform, I optimized plasma sample preparation and applied mass spectrometry for peptidome analysis in septic shock patients.
