Freelance science writer with 1+ years of experience in Data Science, AI, manuscript preparation, scientific editing

Profile Summary

I hold a PhD in Geographic Information Science from a leading university in the United States, and my expertise is in data science, machine learning and spatial analysis. I am an invited peer-reviewer for several top-tier journals and have authored 14 scientific manuscripts. I also have 10+ years of experience presenting research data (both poster and oral presentations) at international scientific conferences. I can provide help with experiment and study design, manuscript writing, editing, and other forms of data communication viz. crafting presentations, website design, and content editing. I have worked as a consultant for pharmaceutical companies designining AI based solutions for customer relationship management. I have also helped state and county level transportation authorities in making sense of big data on transportation movements.
