Faculty cluster hire: promoting collaboration and addressing gender bias in academic hiring



Boyce Thompson Institute





In the world of academic science, hiring new faculty members typically follows a predictable pattern: candidates apply individually and are evaluated primarily on their personal achievements. What if there was a way to build more collaborative, diverse teams of scientists from the very start? That's exactly what the Boyce Thompson Institute (BTI) set out to do with their innovative "cluster hire" approach.

The traditional academic model often fails to recognize and reward team-oriented accomplishments, leading to a systemic bias favoring individualistic or "agentic" stereotypes of success. Recognizing the limitations and biases of this model, BTI embarked on a mission to create a hiring process that values teamwork and inclusivity.

"Our goal was to find scientists who thrive in a collaborative environment and to break down the barriers that discourage many, and disproportionately women, from joining or attempting to advance in academia," said Professor David Stern, author of the discussion recently published in Trends in Plant Science detailing the cluster hire process, and who was BTI’s president during the initiative, which took place in 2018-2019.

Here's how it worked: After an initial round of applications, promising candidates were invited to a symposium, where they had 15 minutes to present their research, followed by 90-minute poster sessions. The next day, they participated in brainstorming sessions, working together to develop exciting new research proposals. This approach allowed BTI to evaluate not just individual brilliance but also each candidate's ability to work in teams and contribute to interdisciplinary ideas.

The most intriguing proposals led to a second round of interviews, where small groups of scientists presented more detailed plans. Importantly, these were not binding research commitments but rather a way to showcase how well the candidates worked together.

The results were striking. Faculty searches in biology typically attract only about 25% female applicants, whereas 45% of the shortlisted candidates in the cluster hire were women. Even more impressively, eight out of the final 13 were female. The emphasis on collaboration seemed to resonate strongly with women in science.

Another unexpected benefit was the diversity of scientific backgrounds among applicants. By focusing on building new collaborative teams rather than filling specific departmental slots, BTI attracted excellent candidates from fields adjacent to plant science, such as microbiology and structural biology. This interdisciplinary approach has the potential to spark innovative research directions.

The impact of this hiring method extends beyond BTI. Other institutions have shown interest in adapting elements of the cluster hire process. For example, Cornell University has incorporated some of these principles into its own faculty hiring initiatives.

While it's too early to measure the long-term effects, the initial results are promising. The scientists hired through this process have maintained highly collaborative working styles, often partnering with colleagues outside their initial "cluster." This community-oriented approach was a key goal of the initiative.

The cluster hire represents a bold reimagining of how scientific teams are built. By valuing collaboration from the very beginning, institutions may be able to create more diverse, creative, and effective research groups. As science tackles increasingly complex global challenges, from climate change to food security, these collaborative teams could be exactly what is needed to drive breakthrough discoveries.

Following the Mediterranean diet versus the traditional Western diet might make you feel like you’re under less stress, according to new research conducted by a team from Binghamton University, State University of New York.

The findings suggest that people can lower their perception of how much stress they can tolerate by following a Mediterranean diet, said Lina Begdache, associate professor of health and wellness studies.

“Stress is recognized to be a precursor to mental distress, and research, including our own, has demonstrated that the Mediterranean diet lowers mental distress,” she said. “Thus, one element of the puzzle may be explained by the fact that the Mediterranean diet may be associated with a decrease in the negative components of perceived stress and an improvement in its positive attributes.”  

The Mediterranean diet is plant-based with healthy fats and mostly includes wholesome food and a spectrum of natural colors. The diet stands in sharp contrast to the Western diet, which is known for its high concentration of high-glycemic and low-quality processed foods.

While the Mediterranean diet is known for its benefits to both mental health and physical health, little is known about its effect on perceived stress, which is the idea of how much stress you are under at any particular time.

To assess this, Begdache and her students conducted a survey of over 1,500 people, asking them what types of foods they ate and assessing their levels of perceived stress. Using a machine learning model, the results show that consuming components of the Mediterranean diet is associated with lower levels of perceived stress and mental distress, while consuming Western dietary components is correlated with perceived stress and mental distress.

Begdache said that these results close a gap in the literature because the majority of studies on diet and stress focused on how stress affects dietary choices and quality. She and her team are looking at different aspects of brain function and behaviors in relation to dietary patterns.

The study, “Effects of Mediterranean and Western dietary patterns on perceived stress and mental distress,” was published in Nutrition and Health.

The Earth is home to a diversity of plants with highly varied forms and functions. This extraordinary morphological, physiological and biochemical diversity determines how plants adapt and respond to ongoing global changes, with significant consequences for the functioning of ecosystems. Yet, 90% of current knowledge on the functional diversity of plants concerns only agricultural ecosystems and temperate zones. By contrast, drylands (see inset), making up 45% of the Earth’s terrestrial area, remain underrepresented in the data. These important zones are now directly threatened by increases in aridity, grazing pressure and desertification. We need to understand how plants respond to such pressures before we can establish the possible future evolution of these fragile ecosystems in terms of their biodiversity and functioning. To meet this urgent need, an international team of 120 scientists from 27 countries has carried out the first worldwide investigation of the functional diversity of plants in arid zones.

 

Having developed a standardised sampling protocol, the scientists collected and processed samples from the 301 plant species found across 326 representative plots from all continents (other than Antarctica) to characterise the functional diversity of the zones, generating a total of 1347 full sets of trait observations for analysis. Particular attention was paid to the characterisation of the plant elementome, that is, the diversity of chemical elements and trace elements (such as nitrogen, phosphorus, calcium, magnesium and zinc) found in plants, as these often-unrecorded traits exert a strong influence on how the latter function. Overall, the study involved more than 130 000 individual plant trait measurements.

 

A key hypothesis at the start of the study had been that aridity would reduce the diversity of plants through selection, leaving only those species capable of tolerating extreme water scarcity and heat stress. However, we found the opposite to be the case in the most arid rangelands of the planet, where plants instead exhibit a wide range of individual adaptation strategies. For example, some plants have developed high calcium levels, strengthening cell walls as a protection against desiccation. Others contain high concentrations of salt, reducing transpiration. Although fewer species are observed at local scale than in other regions of the planet (in temperate or tropical zones), plants in arid zones display an extraordinary diversity of forms, sizes and functioning, double that in more temperate climatic zones. This increase in trait diversity occurs abruptly at the point where rainfall volumes drop below the annual threshold of 400 mm. This is also the threshold for a pronounced decline in plant cover and the appearance of large areas of bare soil. To explain this phenomenon, the study’s authors suggest that the loss of plant cover leads to ‘plant loneliness syndrome’, where increased isolation and reduced competition for resources produces high degrees of trait uniqueness and functional diversity that are globally exceptional. This adaptive diversity could equally reflect complex evolutionary histories dating back to the initial colonisation of terrestrial habitats by plants more than 500 million years ago, when these habitats presented extreme conditions for living organisms.

 

This study reveals the importance of drylands as a global reservoir of functional diversity in plants. It provides a fresh lens through which to view plant architecture, the adaptation of plants to extreme habitats, historical plant colonisation of terrestrial environments, and the capacity of plants to respond to current global changes.

 


What are drylands?

Drylands are defined as tropical and temperate zones with an aridity value below 0.65. They cover 45% of the Earth’s terrestrial area and are home to a third of the global human population. They include sub-humid, semi-arid, arid and hyper-arid ecosystems such as the Mediterranean landscape, steppes, savannahs and deserts.

Recent research has uncovered significant genetic and epigenetic variations in blueberry cultivars, particularly between northern highbush (NHB) and southern highbush (SHB) blueberries. The study highlights gene introgression's role in SHB's adaptation to subtropical climates and identifies key genes, such as VcTBL44, associated with fruit firmness. These findings offer valuable insights and resources for future blueberry breeding.

Blueberries, part of the Vaccinium genus, are renowned for their nutritional benefits and increasing global demand. However, cultivation faces challenges like climate adaptability and fruit quality. Modern blueberries have a short domestication history, primarily through interspecific hybridization. These challenges necessitate deeper research into the genetic and epigenetic factors influencing blueberry traits.

Researchers from Peking University and Jilin Agricultural University, in collaboration with international experts, have made significant strides in blueberry genetic research. Published (DOI: 10.1093/hr/uhae138) in the prestigious journal Horticulture Research on May 14, 2024, their study presents a comprehensive analysis of blueberry genomic variation, marking a pivotal moment in agricultural science.

The study involved whole-genome re-sequencing and bisulfite sequencing on various blueberry cultivars to understand their genetic and epigenetic differences. Researchers identified significant gene introgression from V. darrowii and V. ashei into southern highbush (SHB), aiding its subtropical adaptation. They discovered the VcTBL44 gene, crucial for regulating fruit firmness in SHB. Additionally, they found significant differences in DNA methylation patterns between northern highbush (NHB) and SHB, particularly in CHH-DMRs associated with transposon regulation. These findings offer a comprehensive understanding of the genetic and epigenetic mechanisms that have improved blueberry cultivars, providing valuable resources for future breeding programs aimed at enhancing fruit quality and climate resilience.

Dr. Haiyue Sun, a leading researcher in the study, stated, "Our research provides a detailed genetic and epigenetic map of blueberries, offering crucial insights for breeding programs. The identification of key genes like VcTBL44 paves the way for developing cultivars with improved fruit quality and climate adaptability."

The insights from this study have significant implications for blueberry breeding. The genetic and epigenetic resources identified can develop new cultivars more resilient to climate changes and superior in fruit quality. This research enhances our understanding of blueberry genetics and provides practical tools for breeders to meet the growing consumer demand for high-quality blueberries.
