‘Wormnado’ Wiggles its Way to Win at Postdoc Slam

UCSF’s Postdoc Slam is part of a series of events marking National Postdoc Appreciation Week that are organized by the Office for Postdoctoral Scholars, part of UCSF’s Graduate Division.

Slam presenters are judged on their clarity, pace, audience engagement and their ability to avoid scientific jargon. Having received science communication coaching as part of the competition, finalists used metaphors, similes and humor to translate complicated research into engaging talks.

‘Part of our job as scientists is to communicate’

UCSF is home to more than 1,000 postdocs who come to the University from around the world to receive additional mentoring and training following their doctoral degrees. Postdocs play essential roles in USCF scholarly research, often funded by the National Institutes of Health and others in preparation for academic and industry research careers, says UCSF’s new Assistant Dean of Postdoctoral Scholars Chequeta Allen EdD, MBA, FACMPE.

“Postdoc Slam is just the tip of the iceberg in terms of what postdocs are capable of, and we just can’t celebrate them enough,” she said.

Postdoc Slam provides a glimpse of this work, according to Vice Provost of Student Academic Affairs and Dean of the Graduate Division Nicquet Blake, PhD. But it isn’t just about recognizing the next generation of scientists or their work, it’s about equipping them to talk about it, too.

“Part of our responsibility as scientists is to communicate and communicate well to the taxpayers who largely support the research that we conduct,” Blake told the crowd. “The COVID-19 pandemic and the misinformation perpetuated about the lifesaving vaccines has only reinforced how important this is.”

Research adds new word to UCSF lexicon: ‘Wormnado’

Persson’s worm choreography took place in the lab of UCSF Professor of Cell and Tissue Biology Noelle L’Etoile, PhD. The lab uses the tiny worm Caenorhabditis elegans. Because some of its genes are similar to those in humans, the roundworm is often used to research human diseases or conditions like aging. L’Etoile’s lab studies the translucent worms to watch how cellular connections in the wigglers change as they learn, revealing insights into learning and memory that could, one day, foster advances in computing and our understanding of aging.

Still perplexed by the worms marching, Persson did what anyone would. She Googled, searching for “worm vertex” and “possessed worms spiraling.”

“I did some weird searches I would not recommend,” she said during her talk, earning chuckles from the audience. “I did find that Rihanna’s backup dancers once did something pretty similar.”

After months of laboratory research, Persson is still unraveling the phenomena, which she dubbed a “wormnado,” but thinks the elaborate dance may be a hunting strategy. These blind, deaf nematodes were communicating to engage in collective behavior. And the more worms she added to the petri dish the better they got at doing it.

By spiraling, the worms seem to generate a magnetic field, helping them sense conductive materials nearby like the salty bundles of bacteria they consume, Persson told UCSF News. Like a bloodhound uses scent to track its prey, Cenorhabditis elegans may use magnetic fields to find salty snacks in its natural soil environment.

How this postdoc wormed her way into the judges’ hearts

Persson’s comedic delivery and storytelling earned her first place at UCSF’s 2023 Postdoc Slam with a $4,000 purse. She also won an additional $750 for the People’s Choice Award after garnering the lion’s share of about 440 audience votes.

“If you had been in the judge’s corner, you would have heard us all talking about both the amazing humor of the talk,” said one of this year’s five judges, Helen Willsey, PhD, assistant professor in the Department of Psychiatry and Behavioral Sciences, “but also the phenomenal perspective on a life in science and how fun it is to look in your dish and see something weird.”

Kritika Khanna, PhD, took home second place for her presentation outlining her work to better understand the mechanisms underlying asthma and which asthma patients might be best served by experimental treatments being developed at UCSF. Meanwhile, Chris Williams, MD, won third place, with his work uncovering racial disparities in the triaging of Black, Asian and Hispanic patients in emergency rooms, revealing health care worker’s unconscious biases.

Persson plans to pursue a job in academia after completing her postdoctoral work at UCSF, one day heading up her own lab.

Almost 40% of UCSF postdocs enter the corporate sector after leaving UCSF, while almost half find positions within academia within a year of leaving. For those postdocs who pursue academia, about 4 out of 10 will hold tenure-track positions within five years of leaving UCSF. Many remain in California, helping to make the state a leader in medical and health care innovation.
