Hi, I’m Dr Janelle Wagnild.

I help organizations analyze and interpret evidence to provide data-driven answers to challenging questions across topics in health and disease.

What can I do for you?

Data visualization

I specialize in transforming complex data into intuitive, attractive, publication-quality figures. See my portfolio for examples of my published designs.

Evidence synthesis & evaluation

I have extensive experience in collecting, synthesizing, and critically evaluating quantitative and qualitative evidence bases through systematic reviews and meta-analyses.

Data analysis

Drawing on doctoral and postdoctoral training and experience, I have expertise in advanced analysis of both quantitative and qualitative data.

My approach

Collaborative

I have over ten years of experience working with researchers all over the world from diverse disciplines, ranging from global health to clinical medicine and everything in between. I will listen carefully to understand your concerns, priorities, and questions to ensure the final result meets your needs.

Straightforward

Collaborators often tell me one of my signature strengths is my straightforward communication style, especially when talking about complex statistical or scientific principles. I can readily translate complicated information into lucid, user-friendly terminology that is tailored to your discipline or background.

Integrity-focused

My top priority is getting things right. This not only means I take an extremely detailed approach to ensure accuracy and avoid errors, but also means I care deeply about making sure the interpretations we make and stories we tell are true to the data that underpins them.

About me

I completed my PhD in 2019 and started a very successful career in academia, evidenced by a strong track record in publishing scientific papers and securing external research funding. Despite my success, an academic career was never the goal; my obsession with understanding data and the real-world impact it can have on peoples’ health and lives just happened to lead me there.

In 2024 I decided to branch out on my own, contributing my skills in data analysis and interpretation to clients who are making a difference in the world, including the World Health Organization and the NHS in the UK.

Data visualization portfolio at a glance

  • Parallel line plot

    Parallel line plot

    This figure, published here, visualizes participant- and group-level changes from baseline to follow-up in two trial arms.

  • Custom plot to visualize (in)equity

    This figure, published here, visualizes the asymmetric effect of an intervention that was more likely to reach urban men than other groups, particularly rural women.

  • Sankey plot

    Sankey plot

    This figure, published here, shows the movement of participants between categories (in this case, severity of mitral regurgitation) over time.

  • Forest plot

    Forest plot

    This forest plot, published here, shows which sociodemographic groups were less likely to check medicine expiration dates based on population surveys in four African countries.

  • Custom effect size plot

    Custom effect size plot

    This figure, published here, shows the direction, magnitude, and significance of associations between watching TV and food intake. The heterogeneity of measures and studies meant a forest plot would not be possible, so I designed this one-of-a-kind plot as an alternative solution.

FAQ

  • We'll start by arranging a free consultation to determine your needs (and if we'll make great collaborators). Consultations are always zero-pressure and zero-obligation, so don’t hesitate to reach out!

    You can use the form below to get started or send me an email at janelle@jmwconsulting.co.

  • Pricing is based on both the project's scope and your desired timeline. Rates will always be discussed and agreed in writing before we begin so there are no surprises.

  • Timelines completely depend on the nature of the project, ranging from a few days for something small like the preparation of a figure, to multiple months for something like an evaluation. I always account for revisions in our timeline, to make sure we get things perfect in time for the deadline.

  • Yes! I have listed my main services for simplicity, but I have additional areas of expertise, such as processing of accelerometry data and writing/preparing scientific articles for publication. Please get in touch!
