Undergraduate student in Biomedical Engineering,The City College of New York (2007-2011)

Previous Projects:

  • Designed and led a phase I clinical study to test the saftey and efficacy of novel neural stimulation technology (HD-tDCS). HD-tDCS (High-Density transcranial direct current stimulation) is a technique used to increase saptial focality of tDCS by passing current across the scalp using <12 mm diameter electrodes. However, an increase in focality results in an inevitable increase in current density distribution. This in turn, can lead to discomfort at the site of stimulation. The goal of this study was to optimize “high-density” electrode-gel parameters for electrode durability, skin safety, and subjective pain. Anode and cathode electrode potential, temperature, pH, and subjective sensation over time were assessed during application of 2 mA direct current, for up to 22 minutes on agar gel or subject forearms.
  • Desinged and led a clinical study to explore different chemical and electrical pretreatment methods to further reduce discomfort at the site of stimulation

Current Projects:

  • Use Finite Element Modelling to design an optimal sponge pad design to be used during the application of tDCS.
