Mario A.

Research Scientist | PhD | Medical Writer

I am an independent researcher with 7 years of experience in academia and industry, working on diabetes, nutrition and supplementation, exercise physiology, longevity, and cancer metabolism. 📚 Literature search 📚 Systematic reviews (PRISMA) 📚 Medical data analysis 📚 Dietary supplements review 📚 Academic writing Whatever you need to research and write about, I can help you. We can achieve great things together! As an independent researcher, I specialize in evidence synthesis and systematic reviews across various health-related topics, including nutrition (DOI: 10.1093/nutrit/nuaf179), exercise (DOI: 10.1007/s10103-025-04318-w), and well-being. I have also advised supplement brands on the efficacy and safety of their products. As a medical analyst, I assessed off-label therapies with potential rejuvenation effects, examining all available literature on a specific drug/supplement and writing an extensive risk-benefit analysis. During my PhD, I investigated different approaches to improve glucose control in diabetes: + Islet viability assessment to improve transplant outcomes in type 1 diabetes. + Nutrition in hospitalized patients with type 2 diabetes using automated systems (DOI: 10.1111/dom.14187). + Exercise on exogenous insulin kinetics in type 1 diabetes: a clinical study (DOI: 10.1177/19322968211043915) and a systematic review (DOI: 10.1111/dom.16088). In addition, I worked as a personal trainer and have several sports nutrition and fitness certificates, with a special interest in supplementation and ergogenic aids. What to do next? If you are looking for a versatile researcher or health content writer, just send me a message and we can arrange a video call.
