Post-doc

Wookyung got her Ph.D. in Molecular medicine from Gachon University where she profiled the transcriptome of neural stem cell differentiation models and studied the mechanism of post-transcriptional regulation based on sequencing technologies. In the Yoo Lab, she studies the epigenetic changes in miRNA-mediated neuronal conversion and Huntington’s Disease models. She loves cats and Thai food.

Vicky Church, Ph.D.

Post-doc

Vicky got her Ph.D. at Northwestern University in Biochemistry and Molecular Genetics where she studied mechanisms of miRNA biogenesis. In the Yoo lab she is studying genetic networks that underlie various cell types of the brain, and how these are perturbed during aging and in neurodegenerative disease. She practices yoga daily and loves scuba-diving.   

Zhao Sun, Ph.D.

Post-doc

Zhao received his Ph.D. from University of Iowa for identifying new molecular mechanisms controlling mouse dental stem cell behavior in development and disease. In January 2019, he joined Yoo lab and aims to generate patient-derived neurons in 3-dimensional culture to model adult-onset neurodegenerative disorders. He is a father of two kids and he loves to spend time with family.

David Butler, MD

Assistant Professor; Department of Pediatrics Division of Critical Care

Dave is an Assistant Professor of Pediatrics in the Division of Critical Care Medicine at WashU and provides care for critically ill children at St. Louis Children’s Hospital. During fellowship, he studied the effects of hemorrhage on cerebellar developmental programming. In the Yoo Lab, he is studying mechanisms of neuronal injury and repair, with a specific focus on how age alters these pathways. He enjoys fly fishing, cycling, and spending time with his wife, two cats (Remy & Ferris), and dog (Duncan).

Thomas Mahan, Ph.D.

Post-Doc

Eva Klinman, M.D., Ph.D.

Resident, Department of Neurology

Eva is finishing her neurology residency at WashU and preparing to start a fellowship in movement disorders. During her PhD at UPenn she studied organelle transport and microtubule motor proteins in an ALS system. In the Yoo lab she is studying the contribution of mitochondrial dysfunction and cytoskeletal disarray to the onset and progression of neurodegeneration. In her free time, she enjoys playing with her puppy (Midna), her 30+ freshwater fish, and painting fun designs on her nails.

Kitra Cates

Graduate Student; Molecular Genetics and Genomics

Kitra received a B.S. in Genetics from the University of Georgia (Go Dawgs!) where she analyzed transcription factor binding events integral to early soybean and maize development. Now, she studies the epigenetic factors that drive cell fate erasure and neuronal conversion during miRNA-9/9*-124 reprogramming. When she is not in lab, she enjoys jamming out at concerts, learning different languages, and trying to get some sunshine every now and then.

Lucia Capano

Graduate Student; Molecular and Cell Biology

Lucia got a B.S. in Biology and Neuroscience from Brandeis University where she studied the role of a neuronal transcription factor on the homeostasis of the neocortex. In the Yoo Lab, she studies the age-associated component of tauopathies and regulators of tau splicing. She loves traveling, is an avid runner, and has trained her cat to do tricks.

Kyle Burbach

Graduate Student; Molecular Genetics and Genomics

Kyle has a BS in Genetics and Genomics from UC Davis where he studied the importance of human specific duplicated genes by knocking them out in zebrafish using CRISPR. Kyle now studies the roles of developmental signaling pathways during direct reprogramming to neurons. He is the proud owner of two Corgis and is a major video gamer.

Shivani Aryal

Graduate Student; Neuroscience

Shivani got a B.A. in Neuroscience and Psychology from Wesleyan College. She did her post-bac at Novartis Institutes for BioMedical Research where she studied the regulation of cell fate in airway epithelial cells.
