|| Our goals and commitment
Our team is powered by the shared experiences, knowledge, challenges, and achievements of each of our members. Diversity is key to our success, and we believe that we must take direct actions to build an inclusive environment both within our own group and within our greater academic community.
Addressing racism, implicit bias, and discrimination is important to our group. We believe this should be approached through efforts including advocacy, recruitment, education, and outreach. This includes education on micro/macro aggressions in academia, implicit bias, and the impact of racism on science. It also involves advocating for URM scientists within and outside our local community and promoting their work broadly. We also feel strongly about engaging with future trainees from minority backgrounds who perhaps have never had significant exposure to a career in science or academia.
As one concrete step towards that goal, we are accruing a list of STEM opportunities for high school and undergraduate students who are interested in learning and participating in scientific research. This list, linked below, identifies opportunities that are specific to Emory (or Atlanta-based individuals) and others that are open to all students. Please let us know if other programs should be included so that we can keep this resource up-to-date and comprehensive!
Dr. Steven Sloan is an Assistant Professor in the Department of Human Genetics, at the Emory University School of Medicine. He was born in Phoenix, Arizona and spent the latter half of his childhood in South Florida. For his undergraduate degrees in Biomedical Engineering and Biochemistry he attended the University of Miami, FL.
Steven received his MD and PhD degrees at Stanford University in the laboratory of Ben Barres, where he became fascinated with glia--the understudied and mysterious cell types that adjoin neurons within the nervous system. Given his interests in human medicine, Steven spent his PhD investigating the functions of human astrocytes. Along with his colleagues, he developed techniques to purify and profile each of the major CNS cell types from the rodent and human brain and created resources to distribute this information so that it could be utilized by the entire neuroscience community.
Recognizing that studying human glia from primary tissue had inherent limitations, Steven completed a post-doctoral fellowship with Dr. Sergiu Pasca at Stanford to develop a human induced pluripotent stem cell 3D model of cortical development called human cortical spheroids (hCS). This is an ideal system for interrogating human cortical development and specifically glial development in both healthy and diseased states. Steven joined the Emory faculty in the fall of 2018, where his lab studies glial development and the role these cells play in neurodevelopmental and neuropsychiatric disease.
In his free time, Steven can be found training for triathlons and spending time outdoors and with his family (including the lab's first two members, canines Kevin and Ben).
Kevin the Dog has never held a pipette before, but he has spent his life perfecting the delivery of moral, emotional, and physical support (snuggles). He looks forward to meeting new people who share his passion for glia and is always willing to give his TED Talk on how 'work-life-balance' should be reframed as 'sleep-life-balance'.
