Bianca Jones Marlin

Bianca Jones Marlin is an American neuroscientist and the Herbert and Florence Irving Assistant Professor of Cell Research at the Zuckerman Institute at Columbia University in New York City. Marlin studies the epigenetic mechanisms that enable trauma experienced by parents to be passed on to offspring in rodent models. Marlin's graduate work uncovered the fundamental role for the hormone oxytocin in maternal behavior, for which she was awarded the Donald B. Lindsley Prize in Behavioral Neuroscience for Outstanding Ph.D. thesis as well as the STAT Wunderkinds Award for her groundbreaking findings.

Early life and education edit

Marlin grew up in Central Islip, Long Island with a family structure that influenced her career trajectory.[1] Marlin's biological parents, whom she lived with, were also foster parents.[2] Growing up with both biological and non-biological siblings piqued Marlin's interest in genetics at a very early age.[2] Listening to difficult stories from her non-biological siblings was a driving contributor to her interest in how parental relationships and experiences impact children.[3]

Marlin's high school performance earned her a scholarship to financially support her first semester of college at St. John's University.[4] While at St. John's University, she pursued a dual degree in biology and adolescent education and was actively involved in student leadership and research.[4] As an undergraduate student, Marlin participated in on-campus research and two summer research programs: one at Vanderbilt University and another at the Massachusetts Institute of Technology (MIT).[5]  At MIT, Marlin worked under the mentorship of Martha Constantine-Paton and won an award for her research poster at the end of the summer.[4] In 2009, Marlin received a B.S. in biology and a B.S. in Adolescent Education from St. John's University. At graduation, she was honored with the Distinguished Student Leader Award for her service as the President of the student government.

Following graduation, Marlin become a New York State certified teacher and taught at NEST+m, a New York City Department of Education school for gifted and talented students, where she had student taught during her undergraduate years. During her time at Nest+m, she taught seventh and tenth grade science and Advanced Placement (AP) Biology.[6]

Doctoral research edit

From 2009 to 2015, Marlin pursued her graduate degree at the New York University School of Medicine Graduate Program in Biology and Physiology.[4] Marlin's Ph.D. research explored the role of the hormone oxytocin in maternal behavior[6] and auditory cortex plasticity during critical periods of brain development.[7] In 2011, she published a peer-reviewed article describing the importance of excitatory-inhibitory balance (E-I) in determining the duration of critical period plasticity for auditory cortical frequency tuning— since after birth the auditory cortex is not yet tuned.[7] This work laid the foundation for Marlin to explore how oxytocin shapes social cognition and modifies brain circuits to prompt maternal care toward pups. Rodent mothers (called dams) will retrieve pups when separated from her and/or the litter when triggered by ultrasonic vocalizations emitted from the isolated pups.[8] Typically, dams respond to pup calls, while virgin females do not— suggesting that plasticity in the auditory cortex occurs after the birth of a litter to activate dams to respond.[8] Marlin hypothesized that this plasticity in the auditory cortex was driven by oxytocin because 1) dams release oxytocin following birth to promote bonding, and 2) virgins only respond to pup calls when artificially administered oxytocin.[8] Marlin found that oxytocin sensitized the auditory neural circuits in the auditory cortex and caused long-term changes in the E-I balance.[8] The change in E-I balance accounted for the stable spike-timing precision that is observed in dams (or oxytocin-exposed virgins), but not virgins, when responding to pup calls.[8]

Following Marlin's discoveries regarding the role of oxytocin in pup retrieval, she conducted additional work with colleagues in the Robert Froemke Lab exploring oxytocin's biological role in the social transmission of maternal behavior.[9] In their study, published in Nature,[8] they show that oxytocin neurons in the brain region responsible for the release of oxytocin, the paraventricular nucleus (PVN), are activated by social interaction and that these neurons gate cortical plasticity in response to pup calls. They also show that virgins who are co-housed with experienced mothers, and who visually observed maternal pup retrieval, have increased activation of oxytocin neurons in the PVN and exhibit alloparenting behaviors— suggesting that maternal behavior can be acquired through social transmission.[8]

Marlin's graduate discoveries not only show functional lateralization of the mammalian brain, but also a dedicated, oxytocin-dependent neural circuit for maternal behaviors and adaption following birth.[8] This line of research was highlighted in popular media including National Geographic,[10] the Los Angeles Times,[11] Science Magazine,[12] and Discover Magazine's Top 100 Stories of 2015.[13]

Postdoctoral research edit

From 2016 to 2020, Marlin was a Postdoctoral Research Fellow at Columbia University under the mentorship of Nobel Laureate Richard Axel.[6] In Axel's lab, Marlin explored how trauma experienced by parents is passed to subsequent generations (i.e., transgenerationally) through epigenetic mechanisms.[2] Marlin and team paired odor cues with a shock in adult mice, and then subsequently studied the neural and behavioral changes in offspring, who had never experienced the shock-odor pairing. Marlin's work on this subject has been featured in popular media including Science Friday[14] and The Washington Post.[15]

Faculty research edit

In 2020, Marlin joined the faculty at Columbia University in the departments of Psychology and Neuroscience. The Marlin Lab at the Zuckerman Institute continues to explore how organisms unlock innate behaviors at appropriate times, and how learned information is passed to subsequent generations via transgenerational epigenetic inheritance using a combination of neural imaging, behavior, and molecular genetics.[14]
