About Gregor Weber
A medical scientist working where laboratory research, clinical evidence and public understanding meet.
The interesting part of biomedical science is rarely the discovery. It is what has to be true before anyone can act on it.
That gap — between a result and a decision — is where most of my work has happened.
Biography
In brief
Gregor Weber is a medical scientist based in San Antonio, Texas, working across infectious diseases, immunology, vaccines and medical affairs.
His peer-reviewed research has centred on how bacterial pathogens sense and respond to their surroundings — in particular Vibrio cholerae, the organism that causes cholera, where a folded piece of RNA acts as a temperature switch that makes virulence genes readable only once the bacterium has reached a host — and on how established antibiotics can be made more effective against the drug-resistant biofilms that make some infections so persistent. Those papers are listed, with links to the original sources, under research and publications.
Alongside the laboratory work, his interest is in the step that comes after a result: what has to be true before a finding can be acted on, and how to explain that to the people the decision affects.
A fuller biography, including positions, education and affiliations, is being prepared and will be published once each entry has been confirmed against its source.
Background
Positions and education
2023 – 2025
Key account manager, US commercial
Bavarian Nordic
Product training across a five-vaccine portfolio, and customer education for the launch of a virus-like-particle vaccine for chikungunya. Accounts across fifteen states: health departments, hospital systems, integrated delivery networks, universities and infectious-disease clinics.
2020 – 2023
Associate director, global medical affairs — viral hepatitis
Gilead Sciences
Led the first integrated evidence plan for hepatitis B at the company, and managed a portfolio of 67 active post-marketing studies. Oversaw medical and scientific review of materials, reviewed investigator-initiated research proposals, and served on the independent medical education committee.
2019 – 2020
Senior medical science liaison
Emergent BioSolutions
Scientific and clinical training for European medical and commercial colleagues, and presentation of data at international advisory board meetings.
2017 – 2019
Medical science liaison
PaxVax
Supported the US launch of a cholera vaccine — twenty years after the doctoral work on the bacterium it protects against. Identified educational gaps and built the medical-affairs onboarding curriculum from nothing, then trained the field commercial team.
2015 – 2017
Postdoctoral fellow
Naval Medical Research Unit
Wound infection caused by Staphylococcus aureus and Pseudomonas aeruginosa, and whether nanoparticles and laser treatment could help antibiotics reach bacteria inside a biofilm.
2012 – 2015
Postdoctoral fellow
University of Texas at San Antonio
Multivalent biodefence vaccine development against Francisella tularensis and Yersinia pestis.
2012
PhD, cell and molecular biology
University of Texas at San Antonio
Dissertation: “Characterization of toxT Translation and Virulence Gene Activation in Vibrio cholerae” — how the cholera bacterium decides to switch its virulence genes on.
2005
BS, biology — honours
University of Texas at San Antonio
2021
Values at Work Award
Gilead Sciences
2019
Just In Time Award
Emergent BioSolutions
For presenting cholera vaccine clinical data to European leadership and partners.
2011 – 2012
University Teaching Fellow, Teaching and Learning Center
University of Texas at San Antonio
A $25,000 fellowship — teaching treated as a discipline rather than a duty attached to research.
2009 – 2010
South Texas Center for Emerging Infectious Diseases Scholarship
University of Texas at San Antonio
A $21,500 scholarship.
How I work
A short note on method
Three habits shape most of what appears on this site.
Say what is known, and say what is not
Uncertainty is part of the finding, not a blemish on it. An explanation that hides the limits of the evidence is not simpler — it is less useful, and it ages badly.
Give a number its denominator
Almost every misleading health statistic in general circulation is a numerator without a denominator, or a relative change presented as an absolute one. Naming both is usually all the correction that is needed.
Define the word the first time it is used
Technical vocabulary exists because it is precise, not to keep people out. Every article here defines its terms on first use and collects them where a reader can find them again.
