If the postdoc had intellectual contribution to the work, they merit authorship. How critical the contribution is to getting the paper published also matters. Quality of the contribution regardless of the number of authors.

Our faculty write a reflective essay that frames accomplishments to show intellectual and scholarly growth. The letter from the chair is also important to provide disciplinary context. The key is a multi-factorial evaluation and a holistic assessment of disciplinary excellence.

What matters is the intellectual contribution of the author to the work. We have many faculty working in large collaborative projects that only have multi-author publications. We look for an explanation of their role to assess intellectual merit and leadership.

Advancing transcriptomic profiling of airborne bacteria | Applied and Environmental Microbiology Airborne microorganisms are found all around us, indoors and out. Airborne microbes and non-living biological particles (bioaerosols) are central to environmental health and climate processes (1). Atmospheric bioaerosols can spread allergens, toxigenic agents, and infectious disease, act as cloud condensation and ice nuclei (2, 3), and may impact carbon speciation within clouds (4, 5). Within the built environment, bioaerosol inhalation is a primary route of microbial exposures, in addition to those associated with surface fomites and water sources (6). Although treated water and fomites have been extensively studied as routes of microbial exposure for humans, bioaerosols are a relatively understudied route of great potential importance to environmental health (6). Within indoor environments, studies have examined the microbial composition and viability of aerosolized organisms (6), sources and relative fluxes of bioaerosols (7), their genomic functional capabilities, and transcriptional activity interpreted from DNA and messenger RNA (mRNA) sequencing. With the growing body of bioaerosol dynamics research, the metabolic activities employed by airborne organisms to survive within an aerosol are gaining increased attention. Compiling and deciphering mechanistic responses underpinning microbial survival in air are indispensable toward understanding their persistence in an airborne state, indoors or out, and may assist in designing better engineering interventions that can selectively inactivate live bioaerosols in relevant scenarios.

Exploring sub-species variation in food microbiomes: a roadmap to reveal hidden diversity and functional potential | Applied and Environmental Microbiology Different strains belonging to the same species can vary drastically in their functional potential, resistances, and pathogenicity. In microbial communities, within-species variations can contribute to the distinct function and properties of entire microbiomes. In food systems, such within-species variation therefore conveys unique characteristics and influences the quality and safety of a product (1โ€“5). The resulting properties can be unique to an extent that it allows for the authentication of protected designation of origin and protected geographical indication products by tracking distinct associated strains (6, 7). Furthermore, strain tracking plays a crucial role in monitoring and mitigating disease outbreaks and contamination in food production facilities (8). Hence, as these effects are particularly easily observable, literally tastable, fermented foods and food systems are an ideal model for studying within-species diversity. Additionally, their wide availability, greater number of culturable species, and relatively simpler microbial consortia enhance their suitability as study systems (9). But how can these complex microbial communities and their variation within be efficiently and comprehensively studied? Here, we give examples for the effect of within-species diversity in food systems, review state-of-the-art methodologies, and showcase their applications.
