Current Lab Members

Principal Investigator


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.

 

Lab Members


Susan Maloney, PhD. (Assistant Professor in Psychiatry) Susan’s primary research interest is understanding the impact of genetic and environmental liabilities for intellectual and developmental disorders (IDD) on neural circuit function. Her current focus is how IDD liabilities disrupt developmental trajectories, social circuits, motor function, and the roles in these areas of the serotonin, oxytocin, and opioid systems. When not sciencing, Susan spends small amounts of time enjoying a large variety of hobbies. She most enjoys spending time with friends and family and winning at board games.

Teaching
Kayla Nygaard (Graduate Student) Kayla hails from small town Minnesota (cue John Mellencamp) where she grew up collecting ladybugs on dandelions and reading books by the light of the moon. She decided to study Biology at Carleton College and, when she wasn’t saving puppies from tornadoes, she spent her summers researching the coloration of lizards and learning how to lasso the little guys out in Colorado. Leaving the lizards behind in 2012, she joined Teach For America and spent the next 4 years trying to cram scientific knowledge into the brains of reluctant children in both Kentucky and Massachusetts. Kayla is now settling into life as a Molecular Genetics and Genomics graduate student and quite likes the opportunities in nearby Forest Park. You might catch her running or playing ultimate frisbee on a warm day when she’s not in lab. While she would love to study the effects of environmental stress on animal behavior through the lens of genetics, she thinks videotaping Nathan’s back-flipping mice is pretty fun too! Kayla also holds the record for longest submitted bio for the lab’s people page.

 


Allen Yen (Graduate Student) Allen is a graduate student in the Developmental, Regenerative, and Stem Cell Biology program. Before coming to WashU, he received a BS in biomedical engineering and a MS in biomedical research technologies from Boston University. He is interested in investigating the role of gene-environment interactions in the development of autism spectrum disorders. He is also interested in applying new technologies to address these complex questions. Outside of the lab, he enjoys camping, photography, and going to live music shows.

 


Jiayang Chen (Graduate Student) Jiayang Chen is a graduate student in Molecular and Cell Biology program. And Wiki is his secret English name that only several people know about. He earned his Bachelor’s degree in biological sciences at Fudan University, China. Before coming to WashU, he worked as research assistant to investigate brainstem synaptic function and visual system development in neurological disorders. In the Dougherty Lab, he has continued pursuing his interest in studying neurodevelopmental disorders, especially autism spectrum disorder (ASD). Other dreams (hobbies?) outside the lab: becoming a marine mammal zoologist, winning badminton Olympic gold medal, being recognized as a professional photographer, and traveling around the world.

 


Simona Sarafinovska (Graduate Student) is an MSTP candidate joining 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 (Rotating Graduate Student) Sarah is a rotation 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.

 


Kelli McFarland White, M.S. (Research Lab Supervisor) Kelli is excited to return to Washington University after a brief stint working for a medical device startup company.  Upon completing her Master’s (a long, long time ago) studying both the evolution of color vision in fishes as well as mandibular evolution of the African scaly-tailed flying squirrel, she enjoyed a year teaching high school biology.  The vast majority of her career, though, has been spent managing a biomedical engineering lab at WUSTL.  Outside of the lab, Kelli is a yoga teacher, a mom to a radical 3 year old, and a wife.  She loves being active outside; trail running, cycling, camping, and now even outdoor strength training (thanks, Covid).  Once upon a time, she even played roller derby and was a kickboxing instructor.  Kelli now finds contentment in her current, “gardening phase of life.”

 


Yating Liu (Programmer) Yating has a Bachelor’s in biology, Masters in nutrition and computer science. She is interested in software development, data science/engineering, and getting new technical skills and etc. Besides these, she enjoys a variety of outdoor activities: running, hiking, biking, kayaking, and wandering at the zoo. She loves her cat named Maoqiu (furry ball) and is eager to get a big dog in the future.

 

Raylynn Swift, M.A. (Behavior Technician) Raylynn Swift is a research assistant in the lab supporting mouse behavioral research. She graduated from the University of Missouri-St. Louis in 2020 with a master’s degree in psychology with an emphasis in behavioral neuroscience.
