Zandra L. Jordan
Director, Hume Center for Writing and Speaking, Writing and Rhetoric Operations
BioRev. Dr. Zandra L. Jordan is Director of the Hume Center for Writing and Speaking. A trained rhetorician and ordained Baptist minister, she holds a B.A. in English from Spelman College, a M.A.T in English from Brown University, a MDiv with Certification in Black Church Studies from Emory University, and a PhD in English and Education from the University of Michigan. Her current scholarship focuses on womanist ethics, racial justice, and writing center administration. At Stanford, she also serves as a Chaplain Affiliate with the Office for Religious and Spiritual Life. Beyond Stanford, she serves on the ministerial team at UAMEZ Church in Palo Alto. Dr. Jordan is a proud member of the San Francisco-Peninsula Alumnae Chapter of Delta Sigma Theta Sorority, Incorporated and the San Jose (CA) Chapter of The Links, Incorporated.

Siddhartha Joshi, PhD
Senior Research Scientist, Neurosurgery
BioI am a neuroscientist with over 20 years of experience in empirical, hypothesis-driven research. My knowledge and expertise cover a wide range of topics and methods within systems neuroscience including sensory perception, neurophysiology and neuroanatomy, eye-movements and pupillometry. My research is focused on how the brain represents and uses sensory information to drive goal-directed behaviors and in exploring how intrinsic neuromodulatory systems influence the neural circuits that drive such behaviors. At Stanford, I am looking to channel my experience towards studying human neural signals that underlie computations governing pain and attention.
My work thus far [1-4] supports the idea that there is a need for simultaneous measurements of behavior, brain state and large-scale cortical activity to understand how the brain’s circuits: (i) are modulated by ascending sympathetic activation and (ii) provide top-down control of descending sympathetic control. These are technically challenging experiments [3,4] that have thus far largely been explored in animal models. My current goal is to leverage opportunities to directly measure human brain activity via electrodes implanted for monitoring epilepsy. Towards this end, I will use state-of-the-art neurophysiological, behavioral, pupillometric techniques combined with quantitative analyses.
