Profile Summary

I am Mariana, a PhD in Biochemistry with a strong academic foundation and a profound passion for integrating science, data, and communication. With over a decade of experience in oncology research at a University Hospital in Buenos Aires, I have successfully managed research projects, mentored students, and contributed to several international publications. In addition to my academic work, I have developed a rewarding second career as a freelance professional, collaborating with clients worldwide on projects ranging from medical data scrubbing and image annotation to AI training, SEO content creation, and virtual assistance. I possess a natural curiosity, exceptional organizational skills, and a preference for structured work environments. Whether curating oncology data from clinical guidelines, proofreading scientific manuscripts, scheduling property viewings across multiple time zones, or crafting alt text for lifestyle websites, I thrive on delivering precise and meaningful results. I continuously seek opportunities to adapt to new challenges, master new tools (such as WordPress and Python), and ensure that my work adds value to those who benefit from it. Fluent in both Spanish and English, with a working knowledge of Portuguese and currently learning Italian, I value cross-cultural and multidisciplinary collaboration. My primary objective is to bring clarity to complex concepts, whether in the realm of clinical data analysis or transforming a client's vision into a well-executed project. If you are seeking a professional who combines scientific rigor with creative problem-solving, autonomy with collaborative engagement, and precision with a personalized approach, I would welcome the opportunity to connect.
