Forrest Dylan Rogers, PhD | CV (2024)

Co-advised by Dr. Ricardo Mallarino in the Department of Molecular Biology

2023 Postdoctoral F32 Award from NICHD
2023 New Investigator Award, Society for Behavioral Neuroendocrinology
2022 Cold Spring Harbor High Throughput Neuroanatomy course scholarship
2022 Society for Neuroscience Trainee Professional Development Award

Forrest is principally interested in elucidating the neurobiological causes and biobehavioral consequences of parental care. He is leading a series of projects to understand how functional brain connectivity and gene expression patterns contribute to natural variation in paternal care using biparental African striped mice.

Forrest received his PhD in 2020 from the University of California, Davis. His doctoral work, completed under the advisement of Dr. Karen Bales, investigated how compositional variation in early life parenting structures alters biobehavioral development in socially monogamous and biparental prairie voles (Microtus ochrogaster). As a trainee in the NIMH-sponsored (T32) Bay Area Affective Science Training Program, he completed additional training in human psychophysiology under the advisement of Dr. Wendy Berry Mendes at the University of California, San Francisco. Forrest completed his B.S. in Biological Science (College & Departmental Honors) and his B.A. in French from Oklahoma State University.

Rixing Lin, PhD:

2023-2026 C.V. Starr Postdoctoral Fellow, Princeton

Rixing received his undergraduate degree (B.A.) in cell biology and neuroscience from Rutgers University-New Brunswick (NJ, USA). He received his doctoral degree (Ph.D.) in neuroscience from McGill University (Montréal, Canada), under the supervision of Dr. Gustavo Turecki, where he studied the role of non-coding RNA in major depressive disorder and antidepressant treatment response. As a McGill University and Mitacs Globalink sponsored trainee, Rixing received additional training on single-nuclei approaches to assess genomic architecture at the Icahn School of Medicine at Mount Sinai (NY, USA) under the advisement of Dr. Schahram Akbarian.  

Jay Kim, PhD:

2024 Society for Neuroscience Trainee Professional Development Award
2024-2025 UCHV Future Values Fellow

Jay completed her BSc Hons degree in physiology and pharmacology, MSc degree in pharmacology, and PhD in pharmaceutical sciences at the University of Saskatchewan (Canada). Her doctoral thesis with Dr. Robert Laprairie focused on the pharmacodynamic interactions between cannabinoids and other neuropsychoactive drugs. At the University of Saskatchewan, Jay was also a graduate teaching fellow and a sessional lecturer for the professional pharmacy program. In the Peña Lab, Jay is developing a novel CRISPR-based epigenome editing tool for application in cells and mice.

Rebekah Rashford, PhD

2020 National Science Foundation GRFP Honorable Mention
2022 NIMH NRSA F31

Rebekah is leading research to understand how early life stress alters chromatin architecture in a subset of stress-responsive neurons, and reversing such changes to promote resilience using custom CRISPR-based epigenome editing tools in vitro and in vivo.

Rebekah was a Meyerhoff Scholar and Biological Sciences major at University of Maryland, Baltimore County. Previously, Rebekah researched ribosomal protein binding during ribosomal RNA maturation. She defended her dissertation in the Peña Lab in June, 2024.

Data scientists & Computational Biologists

Nibal Arzouni, PhD

Research Software Engineer

Nibal is interested in computational neuroscience at the molecular, genetics, and imaging levels. He received his PhD from the University of Southern California (USC) where he was a member of the imaging genetics group at the Lab of Neuroimaging (LONI). His doctoral research work was focused on dementia especially Alzheimer’s disease (AD) using multi-modal data. He studied differentially expressed genes for late onset AD, ethno-racial disparities in AD, and environmental pollution and its effects on human health and brain. He also holds degrees in electrical engineering, biomedical engineering, and computer science from the University of Michigan Ann Arbor and USC. His computational interests lie in using engineering/computer science machine learning and signal processing techniques for neuroscience research. He is a joint member with Lewis Sigler Institute for Integrative Genomics and Princeton Neuroscience Institute.

Mike DeBerardine, PhD

Research Software Engineer

Mike is a Research Software Engineer shared between the Krienen and Peña labs here at PNI. In both labs, Mike works on the computational analysis of single-cell genomics data. He has a BS in Biochemistry from Brown University and a PhD in Genetics and Genomics from Cornell University, where, under mentor John Lis, he used functional genomics methods to study the mechanisms through which gene transcription is regulated. In his free time, Mike enjoys cooking, music, hiking, and shredding guitar.

Research Specialists

Shannon Bennett

2024 Society for Neuroscience Trainee Professional Development Award
2022 Society for Behavioral Neuroendocrinology Welcome Initiative Awardee

Shannon is leading research on how thyroid hormone signaling mediates the impact of early life stress on reward circuit development.

Shannon majored in Biology with a concentration in Neuroscience at Penn State. Before joining the Peña Lab, she was an associate scientist at a pharmaceutical company for several years, where she performed in vivo pharmacokinetic studies.

Danielle Roberts

Danielle joined the Peña lab in 2024 to become our lead histology expert and Cell Culture Technician. 

Prior to joining the lab, she worked in Dermatology in both clinical settings and research. She is currently finishing up her Post Baccalaureate Pre-Medical program at Fordham University. 

Danielle completed her BS in Economics from the University of Delaware where she played basketball for the NCAA D1 Women’s Team. 

Graduate Students

Addie Minerva

Jointly advised by Dr. Ilana Witten.

2024 Princeton Procter Fellowship
2021 National Science Foundation GRFP Awardee

Addie is using both single-nucleus RNA-seq and single-cell 2-photon imaging to understand brain reward circuit alterations associated with stress resilience and susceptibility.

Addie majored in Neuroscience & Behavioral Biology with a minor in Predictive Health at Emory University, where she worked with Leonard Howell to investigate the prosocial effects of MDMA. After graduating, she worked with Lisa Gunaydin at UCSF studying how projections from the the prefrontal cortex regulate subcortical areas involved in motivated behavior.

Jovian Cheung

Jointly advised by Dr. Annegret Falkner

2024 National Science Foundation GRFP Awardee

Jovian is interested in how early-life thyroid hormone depletion leads to latent differences in network responses to acute stressors in adulthood. She is examining brain-wide activity, performing in-vivo recordings, and using snRNA-seq to dissect the developmental & acute roles of thyroid hormone in stress responsivity.

She majored in Cognitive Science and minored in Neuroscience at UCLA, during which she worked in Dr. Scott Wilke's lab to investigate the role of the anterior cingulate cortex in effort-based decision making. Outside of the lab, Jovian enjoys contributing to scientific communication and outreach. She also likes art and taking photos of flowers

Siena Dumas Ang

Advised by Dr. Barbara Engelhardt, moonlighting in the Peña Lab

2021 National Science Foundation GRFP Awardee
2019 NPSC Fellow

Siena graduated with a triple degree in Computer Science, Mathematics, and Dance from the University of Washington. Prior to graduate school, she spent four years at Microsoft Research on the DNA Storage team.

Visiting: Kaitlin Sullivan

2023 Friedman Award for Scholars in Health

Kaitlin is a visiting graduate student from The Cembrowski lab at UBC. She is learning and applying epigenome sequencing approaches to understand how stress alters the 3D structure of DNA across the lifespan.

Undergraduate Students

We welcome interest from Princeton undergraduates hoping to join the lab for research experience and thesis projects, but unfortunately cannot take everyone. The best time to contact Dr. Peña is over the summer or beginning of the Fall when we have turnover in current undergrads and additional mentoring capacity. Priority will be given to students who are able to work in the lab for at least one summer (with OUR/department funding). No experience necessary - just enthusiasm and your time.
