Joe Dougherty, PhD

Lab Head

I am broadly interested in how a single genome creates the cellular diversity that is discovered in the brain, and how perturbations of specific cell types in the brain may lead to disorders of the nervous system, as well as alterations of normal behavior.  We approach these questions using the tools of mouse transgenics and conditional knockouts, but guide our studies using information gleaned from human genetics studies. We are looking for postdocs and students.  Feel free to contact me.

Mike Vasek, PhD

Staff Scientist

Mike earned his PhD in Neuroscience at WashU studying memory impairment and synapse elimination during viral encephalitis. His main research interests are mechanisms of learning and memory. Outside of the lab, Mike enjoys watching his 1-year-old son figure things out, cooking, playing ultimate frisbee, training his cats, and keeping African cichlids.

Allyson Schreiber

NICU Fellow

Allyson earned her MD, PhD at Louisiana State University Health Science Center – New Orleans, where she studied the neurobiology of stress and addiction. She completed her pediatric residency at Children’s National in Washington, DC before moving to St. Louis for NICU fellowship. She is now broadly interested in how early life events and exposures can contribute to neurodevelopmental disabilities. Outside of the lab, she enjoys trying new restaurants, reading, and relaxing with her cat.

Simona Sarafinovska

Graduate Student

Simona is a MSTP candidate in the neuroscience program. She’s originally from Macedonia and came to the US for her undergrad at Columbia University. Her interest in molecular biology led her to a lab investigating how early-life adversity via epigenetic factors impacts later-life susceptibility to anxiety and depression. Now, she’s more broadly interested in developmental molecular and synaptic processes that drive maladaptive behaviors and susceptibility to psychiatric disorders. During her virtual rotation, she worked on analysis of behaviors in the opioid and Myt1L projects, with a focus on learning new pipelines and methods; she joined the lab in August ’20. In her free time, she loves traveling with her sister, watching TV, and pretending to read Russian literature.

Sarah Koester

Graduate Student

Sarah is a student in the Molecular Cell Biology program. She majored in Biochemistry at the University of Southern Indiana, where she also finished an 11-year cross country and track career that can be described as mediocre at best. Afterwards, she spent 2 years as a research technician in the Di Cera lab at SLU studying enzyme allostery and conformational selection in trypsin-like proteases. Starting graduate school, she is broadly interested in the regulation and functional diversity of RNAs. Outside of the lab, she is the proud pawrent of 2 dogs, an expired runner with all intentions of starting back up again, and probably the only one laughing at her own jokes.

Mari Gachechiladze

Graduate Student

Mari is an MSTP student in the Neuroscience program. She graduated from Georgetown University with a BS in Neurobiology. At Georgetown, she studied the role of APOE4 in Alzheimer’s disease in the Rebeck lab. Afterwards, she spent two years in the Ward lab at the NIH studying frontotemporal dementia using iPSC neuron technology and CRISPR screening. Now, she is broadly interested in discovering epigenetic factors that can predict individual differences in animal behavior. Outside of lab, Mari enjoys dancing, strolling through Forest Park, creating home video parodies with her cousins, and consuming fiction.

Titi Akinwe

Graduate Student

Titi is a graduate student in the Molecular Genetics and Genomics program. Before coming to WashU, Titi graduated with a BS in Neuroscience from Georgia State University. During their undergrad career, they mostly focused on computational neuroscience but became interested in genomics and its applications to Precision Medicine through a SURP at Medical University of South Carolina. This interest was further developed through the OGR program at MGI where they narrowed down their interest to the genetic etiology of neurodevelopmental and psychiatric disorders. They are excited to be co-mentored by Drs. Joe Dougherty and Meaghan Creed on a collaborative project focused on exploring the epigenetic and spatial transcriptomic landscape of ventral pallidum cells in the context of opioid self-administration mouse models. In their free time, they love exploring the local culinary scene, trying out cocktail recipes, dreaming of becoming a DJ on the side, community organizing, and cuddling with their cat.
