Hi, I'm Ahmad Sofi-Mahmudi

I build statistical and research tools that make evidence synthesis, biostatistics, and scientific publishing more reproducible.

My work sits mostly at the intersection of R, Python, Bayesian modeling, meta-analysis, research integrity, and GNU/Linux.

Current focus

  • Population-adjusted indirect treatment comparisons and evidence synthesis methods
  • R packages and Shiny tools for biostatistics workflows
  • Research integrity tooling for citations, retractions, and DOI validation
  • Practical automation for statistical programming and open science

Featured work

Project What it does Stack
mlumr Multilevel unanchored meta-regression for disconnected evidence networks R, Stan, C++
respondeR Responder analysis for continuous outcomes, with R/Shiny/browser tooling R, Shiny
sysreqR Preflight checks for R package system requirements on GNU/Linux R, GNU/Linux
citicious Flags retracted articles and suspicious scholarly citations on academic pages TypeScript
BiostatAgent Claude Code plugin marketplace for biostatistics workflows in R Python, R
cochraneauthors Meta-research on authors of Cochrane Reviews HTML, research methods

Tools I use

R Python Stan Shiny TypeScript GNU/Linux Git

How I think about software

Good research software should be:

  • Reproducible enough for another analyst to rerun it.
  • Transparent enough for a reviewer to audit it.
  • Documented enough for a tired user to understand it.
  • Small and boring where possible; cleverness is not a substitute for reliability.
