One of the great pleasures of working in academic research is in following the progress of our pre- and post-doctoral trainees and former staff members after they leave the lab. We are very proud of all that our lab alumni have accomplished and the good work they continue to do. Below are brief bios of our former lab members and some recent news items.

Where are they now?
The list of bios below is not comprehensive (yet!) and if you are a former lab member reading this, please do send us an update!

Kwang Woo Ko
Former Postdoc, Currently: Scientist II at PTC Therapeutics
Dr. Kwang Woo Ko joined the lab in 2015. His work looked at the roles of Sarm1 and inflammation in neurodegeneration, specifically in the context of glaucoma. In 2021, he accepted a position at PTC Therapeutics where he will continue to work on eye diseases.

Ethan Graf, PhD
Former Postdoc, Currently: Instructor at Mary Institute and Saint Louis Country Day School
Ethan joined the DiAntonio Lab as a postdoc in 2005 and studied the mechanism of synapse development. In 2010, he left to take a position as an Assistant Professor at Amherst College. In 2018, he returned to the St. Louis area and is now teaching at the prestigious Mary Institute and Saint Louis Country Day School.

Catherine Collins, PhD
Former Postdoc, Currently: Associate Professor of Molecular, Cellular & Developmental Biology at the University of Michigan
In 2001, Dr. Collins was the first postdoc to join the DiAntonio lab. Her work examined the role of Highwire in synaptic development. During her time in the lab, she conducted a screen that identified wallenda, the fly homolog of DLK, as a suppressor of the highwire mutant phenotype. After her postdoc, she went to the University of Michigan where she is an Associate Professor of Molecular, Cellular & Developmental Biology and her lab studies signaling pathways that regulate synaptic development and the axonal response to injury.

Susan Culican, MD, PhD
Former Clinical Fellow, Currently: Associate Dean for Graduate Medical Education at the University of Minnesota School of Medicine
Dr. Culican, a pediatric ophthalmologist, joined the lab in 2007. Her research in the lab looked at the role of Phr1 in targeting and synaptic refinement of retinal ganglion cell axons. She later established her own lab at WUSM. In the years since, she has been drawn towards roles in education of clinicians and is currently the Associate Dean for Graduate Medical Education at the University of Minnesota School of Medicine.

Stefanie Geisler, MD
Former Clinical Fellow, Currently: Assistant Professor of Neurology at Washington University School of Medicine
Dr. Geisler joined the lab as a clinical research fellow after being the Chief Resident in Neurology at WUSM. As a physician treating patients with neuromuscular disorders, her clinical insights greatly enriched the intellectual life of the lab. In her research, Dr. Geisler demonstrated that SARM1 is required for the development of chemotherapy-induced peripheral neuropathy, and helped to develop a gene therapeutic targeting SARM1 that effectively blocks pathological axon degeneration in vivo. Dr. Geisler is currently an assistant professor in the Department of Neurology at WUSM where her lab investigates the molecular mechanisms causing peripheral neuropathies and develops therapies for the treatment of these debilitating disorders.

Dan Summers, PhD
Former Postdoc, Currently: Assistant Professor of Biology at the University of Iowa
Dr. Dan Summers was a shared postdoc in the DiAntonio and Milbrandt labs whose work investigated pathways in sensory neurons that regulate protein degradation of axonal survival factors. He is now an Assistant Professor of Biology at the University of Iowa where his lab continues studying cellular pathways responsible for protein homeostasis in developing and diseased neurons.

Chunlai Wu, PhD
Former Postdoc, Currently: Associate Professor of Cell Biology and Anatomy, and Neuroscience at the Neuroscience Center of Excellence, LSU Health
Dr. Wu was a postdoc in the lab from 2002-2008. His research focused on synaptic development and the role of Highwire. He left the lab to take a faculty position at the LSU Health Sciences Center where his lab continues to work on the molecular pathways that shape and support synaptic connections as well as using Drosophila to identify novel molecules that play a role in neuronal development and degeneration.
