Tim Robertson

"Creating Trust in the Time of Ebola"

Tim Roberton is a researcher at the John Hopkins School of Public Health. He visited Guinea in July and spent two weeks with the Guinea Red Cross as part of a study on the Ebola outbreak. He was based in Gueckedou, a town on the Guinea's southern border with Sierra Leone where the current Ebola outbreak began last winter. Roberton and his colleagues interviewed Red Cross staff and volunteers and did research on their work of raising Ebola awareness and teaching families how to protect themselves. Roberton's research found that one of the key reasons the Ebola outbreak got out of control in West Africa in the early days of the crisis was a lack of trust among community members, frontline health workers and the broader health system.

"Grafted neurons and Parkinson disease"

With a combination of high-performance liquid chromographs (HPLCs) and carbon fiber electrodes, we demonstrate that grafted neural stem cells directly release dopamine in the damaged striatum in vivo and partially rescue a Parkinson's disease (PD) model. (i) Primitive neural stem cell–dopamine-like neuron (pNSC–DAn) retained tyrosine hydroxylase expression and reduced the PD-like asymmetric rotation; (ii) depolarization-evoked dopamine release and reuptake were significantly rescued in striatum in vitro (brain slices) and in vivo, as determined jointly by microdialysis-based HPLC and electrochemical micro-carbon fiber electrodes; and (iii) the rescued dopamine was released directly from the grafted pNSC-DAn (not from the injured original cells). Thus, pNSC-DAn grafts release and reuptake dopamine in the striatum in vivo and alleviate PD symptoms in rats, providing proof-of-concept for human clinical translation.

"Miniaturized mobile health monitoring"

When mounted on the skin, modern electronics have the potential to provide health monitoring capabilities for continuous use, beyond the confines of traditional hospital or laboratory facilities. The most well-developed component technologies are, however, broadly available only in hard, planar formats. As a result, existing options in system design are unable to effectively accommodate integration with the soft, textured, curvilinear, and time-dynamic surfaces of the skin. We have developed experimental and theoretical approaches for using ideas in soft microfluidics, structured adhesive surfaces, and controlled mechanical buckling to achieve ultralow modulus, highly stretchable systems that incorporate assemblies of high-modulus, rigid, state-of-the-art functional elements. The outcome is a thin, conformable device technology that can softly laminate onto the surface of the skin to enable advanced, multifunctional operation for physiological monitoring in a wireless mode.
