PhD Consultant | Scientific Editor & Data Analyst | Environmental & Biological Sciences Expert

Profile Summary

I am a PhD-level scientist (PhD graduated from Monash University, Australia) and university lecturer with an extensive international track record, including multiple postdoctoral fellowships (including The University of Hong Kong). I specialize in providing rigorous quality control, methodological verification, and scientific editing for complex manuscripts, technical reports, and research proposals in biological and environmental sciences. My goal is to help researchers, startups, and organizations optimize their scientific documentation, detect methodological flaws, and maximize the impact and clarity of their data.
