Applied mathematical modeller at Biomathematics and Statistics Scotland working on a variety of parasites (mainly gastrointestinal nematodes), vectors (mainly mosquitoes) and sometimes I dabble in Bayesian inference (currently avian influenza in seabirds).

ABSTRACT

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.

Nipped downstairs for a coffee and a short break. My 2 year old took one look at me and shouted, "Go back to work!".

A nice thread highlighting key findings from our new paper estimating parameters of #HPAI in subsequent outbreaks in common terns. We developed a Bayesian inference approach to infer parameters from just carcass counts. #seabirds #statisticalecology #diseaseecology doi.org/10.1111/1365...

Estimating epidemiological parameters of highly pathogenic avian influenza in common terns using exact Bayesian inference
Statistical methodology was developed to understand key processes driving avian influenza in a seabird colony. Using common tern mortality data, it was shown that bird-to-bird transmission dominates ...

I'm going to be on BBC Scotland lunchtime live and the 7 oclock news talking about vector-borne disease risk in Scotland. Fingers crossed all goes well. Going to require a serious caffeine hit after a few relatively sleepless nights since baby #2 arrived on Sunday!

In the latest episode: 🌍🦤 Rewilding isn't just about reintroducing extinct species - it's about allowing natural processes to take control. Many misunderstand it as bringing back wolves and bears, when it's really about humans stepping back and letting nature determine outcomes. 1/9
