Kathryn Leatherbury
Biology PhD Student
Biology PhD student in the Streelman Lab with a research focus in behavioral neuroscience, genomics, and bioinformatics. My research utilizes single-nucleus multi-omic sequencing technologies to investigate how the transcriptomic and epigenomic landscape is modulated across cell-types within the vertebrate brain during complex social & sex-specific behaviors. My work aims to shed insight into the neuronal networks and signaling pathways that regulate gene expression as a strategy for controlling context- and sex-dependent behavioral states.
In my free time I enjoy pretending to be good at pickleball, talking to animals, and painting oil portraits of the squirrels in Piedmont park.
Cait Sullivan
Biology PhD Student
Graduate student in the Biology PhD program, focusing on neural crest development. I am using single-nuclei RNA sequencing to analyze the chronological activation of genes during gastrulation and make comparisons between rock and sand cichlid species.
In my free time I enjoy stargazing, competitive duck herding and paranormal investigation.
Haowen He
Bioinformatics PhD Student
Graduate student in the Bioinformatics PhD program, supervised by Dr. Todd Streelman and Dr. Peng Qiu. My current research interests are in mathematical modeling for data science applications in single-cell genomics. My work pursues (i) developing scalable analytics pipelines for automated analyses of single-cell multiome datasets to enhance the accessibility of large-scale NGS data, and (ii) use omics technologies to investigate the cellular and molecular basis of recently-evolvedsocial behavior in cichlid fishes, linking behavior-associated genomic variation to specific brain cell types and their functions.
In my free time I enjoy playing tennis/pickleball, overcooked, and making boba tea.
Siddhi Vivekkumar Ranbhor, M.S. in Bioinformatics
Research Associate I
Research Associate in the Streelman Lab, I collaborate with PhD students in the lab to explore how transcriptomic and epigenomic landscapes across cell types in the brain influence complex social and sex-specific behaviors in Lake Malawi cichlids. My research involves the use of single-nucleus RNA-seq and ATAC-seq technologies, integrating multiomic data to understand the neuronal networks and signaling pathways that govern these behaviors.
In my free time, I enjoy entering fat-burning zones, decorating small random things, and devouring ice cream sandwiches!
Tucker Lancaster | McGrath Lab
Quantitative Biosciences PhD Candidate
Graduate student in the Quantitative BioScience program, focusing on biological applications of machine-learning and computer-vision. Currently working to improve automated workflows for accurate, high-volume characterization of Cichlid behaviors, including bower-construction and courtship.
Talha Mubeen, Ph.D.
Biology PhD Candidate
I am a dentist who has specialised in orthodontics, currently a Biology PhD student, interested in bioengineering dental and craniofacial tissues. Presently I am working on craniofacial morphogenesis and transcriptomics of dental regeneration.
In my free time, I like making snowmans.
Brianna Hegarty, PhD
Graduated October 2023 | PhD in Biology
I completed my PhD in Biology in October, 2023 and accepted a position at 10x Genomics as a Sr. Customer Engagement Specialist. During my time in the Streelman Lab, my research centered on the genetic and neural signatures underlying variation in evolved social behavior. I utilized cutting-edge single nucleus RNA-seq and spatial transcriptomics technologies to investigate telencephalic neural networks and gene expression patterns implicated in cichlid bower-building behavior at cellular and spatial resolution. In my free time, you can find me raising my wolf-dog, hijacking karaoke opportunities, or falling out of chairs.
George Gruenhagen, PhD
Graduated August 2023 | PhD in Bioinformatics
Studied the single cell transcriptomics of regenerative dental processes in vertebrates and social behavior in Lake Malawi cichlids. Aimed to decipher, interpret, and visualize the complex transcriptomes of cells during these context-dependent biological processes.
In my free time, I like to play volleyball and read thick fantasy books by the lake.
Zachary Johnson, Ph.D.

Zachary Johnson – Emory University | zachary.vernon.johnson@emory.edu
Previous Postdocal Fellow in the Streelman lab whose work focused on investigating the genetic and neural basis of social behavior in Lake Malawi cichlid fishes. Used single nuclei RNA-sequencing to study the neurogenetic basis of bower construction, a complex social behavior whereby males construct bower structures for courtship and mating but not for raising offspring. His research was aimed at understanding how natural genetic variation shapes nervous system function and ultimately behavior.
