My formal training includes general neurosurgery, endovascular neurosurgery and neural stem cell research. As an open cerebrovascular and endovascular neurosurgeon, I treat patients with aneurysms, arteriovenous malformations, cavernous malformations, Moyamoya disease and acute large cerebral vessel occlusions. I have also received extensive training in stem cell research. I worked as a postdoctoral researcher for Dr. Steven Goldman on oligodendrocyte progenitor cell biology. As a neurosurgery resident at Duke University, I transplanted GABAergic neural stem cells into a rat seizure model in my dedicated research year with Dr. Ashok Shetty. After residency and fellowship training, I completed a 1-year fellowship with Dr. Gerd Kempermann on dentate progenitor cell transplantation into a mouse model of deficient dentate neurogenesis. At UC Davis, I started to run an active basic science research lab. I am supported by a K08 to study the mechanism of memory decline in a rat model of intraventricular hemorrhage. I am also supported by an intramural California Institute of Regenerative Medicine (CIRM) grant to achieve perfusion of vascularized human brain organoids in vivo. In 2015, my group developed induced pluripotent stem cells (iPSCs) from the dura of a UC Davis patient. We were subsequently the first group worldwide to publish on vascularization of human brain organoids with iPSC-derived human endothelial cells from the same patient. I work with junior specialists from the Institute of Regenerative Cures under the leadership of Dr. Jan Nolta to generate the vascularized human brain organoids. One of my overarching research goals is to model the human blood-brain barrier with human brain organoids in vitro and in vivo.
Dr. Waldau is a specialist in open cerebrovascular and endovascular treatment of cerebral aneurysms and arteriovenous malformations. His dual training in open surgery and endovascular embolization allows him to choose the best treatment modality for his patients, and sometimes he uses a combination of both approaches to achieve the best results. He also has an interest in stroke and extracranial carotid disease which he can treat with carotid endarterectomy or carotid angioplasty and stenting. With the establishment of the stroke unit at UC Davis, we are striving to provide highly specialized care to our vascular patients to achieve the best outcomes.
Dr. Waldau holds an NIH grant to study the mechanism of memory decline after intraventricular hemorrhage in a rodent model. His further basic science research efforts are focused on understanding the role of dentate gyrus neurogenesis and transplantation of vascularized cerebral organoids for functional recovery after stroke. In clinical research, Dr. Waldau works on robotic solutions for endovascular care.
