SARAH ACKERMAN

LAB DIRECTOR

I am broadly interested in understanding the beautifully complex mechanisms that guide nervous system development. The human brain is made up of billions of neurons that communicate with one another through trillions of specialized connections called synapses. Along with neurons, 50% of the human brain is comprised of a group of cells called glia. I have dedicated my scientific career to understanding how these glial cells- the underdogs of the neuroscience community - instruct proper nervous system assembly and function.

 

To do that, I take advantage of multiple model systems (zebrafish, fly, and mouse) to understand the evolutionarily conserved mechanisms used by glia to guide assembly, maintenance, and function of the nervous system in health and disease. My long-term goal is to use this information to better inform therapies for neurodevelopmental and neurodegenerative disorders. Outside of the lab, I enjoy gardening, baking, trying new restaurants, and taking long walks with my pups.

Sandeep Paul, PhD

Staff Scientist

Dr. Paul is a Staff Scientist who joined the Ackerman lab in September of 2024. Dr. Paul did his Master’s training at Davi Ahilya University in India, where he developed new genetic tools in Drosophila. He then moved on to a successful Ph.D. thesis at Ruperto Carola University in Germany, where he explored zebrafish muscle regeneration (defended in 2009) . In the past 15 years, he has continued to expand his experience in zebrafish development, regeneration, and high-resolution imaging through multiple postdoctoral positions in the USA. Dr. Paul leverages his multi-system background and extensive cloning skills to create novel tools for multiple key projects within the Ackerman lab.

Bonnie Garrett

Technician

I am excited to be entering the field of neuroscience! I have always been curious about the nervous system, from its structure to its function, development to degeneration, and how that affects an organism’s health and its susceptibility to disease. In the Ackerman lab, I am gaining valuable experience on the mechanisms for how glia influence changes in neurons. I received my Bachelor’s in Wildlife Science and Agriculture and spent the beginning of my career working with exotic animals, focusing my skills on animal husbandry and conservation. I believe my background in wildlife science and work with exotic animals will give me a unique perspective, a broader understanding of biological diversity, which can be valuable in studying the nervous system across different species.

Ze Ou, MSc

MD-PhD Student

My name is Ze Ou, and I am a second-year MD-PhD student at Washington University in St. Louis. I aspire to be a neurointensivist-scientist, caring for patients in critical conditions and creating methodologies that improve neuroregeneration after brain injuries. In line with these interests, my research goal is to characterize the structural and functional heterogeneity of astroglia across zebrafish development and then apply these findings to better understand recovery in different brain injury models (e.g. stroke or seizure). To do so, I aim to build a computational framework that can characterize the typical developmental trajectory of astrocytes and predict cell fates in response to varying perturbations.

Dunham Clark

Technician

Since I started my research career, I have been captivated by how the human body organizes itself at a microscopic level to create such a complex final product. At the University of Michigan, I studied the sub cellular components of the circadian clock in Drosophila. In Dr. Ackerman's lab, I am building on my experience in fly while focusing on understanding the cytoskeletal contributions to critical period termination and, exploring the potential consequences that cytoskeletal failures may have on neural development. Outside of the lab, I love to bake, travel, and play trombone!

Maggie Postolache, PhD

Postdoctoral Fellow

My career goal is to be an independent research professor with a lab focused on identifying the cellular mechanisms impaired in neurocognitive disorders, like autism spectrum disorder and schizophrenia. During my graduate training, I gained extensive experience designing and performing electrophysiological experiments to study how synapses in the auditory brainstem are altered with age and varied sensory exposure. In my postdoctoral work in the Ackerman lab, I transitioned to Drosophila as a genetic model system where I can directly connect neural circuit activity, plasticity, and long-term circuit outcomes. I am thrilled to have the support of an NIH F32 (MH139159) to enable this exciting work!

Haley Jetter, MSc

PhD Candidate

I have always been fascinated by how the brain works. During my Master's, I built a custom microscope to compare responses to thermal stimuli across various species of nematode. In the Ackerman Lab, I have switched my focus to understanding the contribution of glial cells to neurodevelopmental disorders. Specifically, I am interested in investigating the molecular mechanisms underlying congenital disorders of glycosylation and brain overgrowth disorders. Outside of lab, I enjoy playing saxophone and clarinet, climbing, foosball, and maintaining my tank of non-mutated fish.

Toby

Toby is interested critters of all sorts, but especially birds and squirrels. He would like to know why they are so fast, and why they can’t be friends. Toby enjoys long walks, lots of treats, and laying in the sun.

George

George (aka Georgie Porgie or Curious George) definitely grew into his name- he is a very curious boy and the best little brother Toby could have hoped for! His top passion in life is food, and he is constantly on the search for more...
