In my position as a Study Director I interface directly with customers to assess customer needs and ensure accurate capture of project specifications in order to develop detailed project plans. I ensure that plans are successfully tracked and seamlessly executed by ensuring that staff understand and are compliant with all policies and procedures to ensure the most efficient operation, and provide customers with the highest quality scientific service.
I am uniquely positioned to develop and execute strategic innovation and improvement initiatives, with the objectives to increase capacity, expand product offerings, improve service quality and improve customer experience. I participate in research validation data analysis and support implementation of new techniques and processes.
Odorant receptors (OR) are strongly implicated in coalescence of olfactory sensory neuron (OSN) axons and the formation of olfactory bulb (OB) glomeruli. However, when ORs are first expressed relative to basal cell division and OSN axon extension is unknown. We developed an in vivo fate-mapping strategy that enabled us to follow OSN maturation and axon extension beginning at basal cell division. In parallel, we mapped the molecular development of OSNs beginning at basal cell division, including the onset of OR expression. Our data show that ORs are first expressed around 4 d following basal cell division, 24 h after OSN axons have reached the OB. Over the next 6+ days the OSN axons navigate the OB nerve layer and ultimately coalesce in glomeruli. These data provide a previously unidentified perspective on the role of ORs in homophilic OSN axon adhesion and lead us to propose a new model dividing axon extension into two phases. Phase I is OR-independent and accounts for up to 50% of the time during which axons approach the OB and begin navigating the olfactory nerve layer. Phase II is OR-dependent and concludes as OSN axons coalesce in glomeruli.
