Shahriar SheikhBahaei, Ph.D.
Dr. SheikhBahaei’s interest in neuroscience stemmed from the usual combination of an aptitude for science and a medical problem (stuttering) that brought him into bioscience at a young age. Dr. SheikhBahaei received his bachelor’s degree from the University of California at Berkeley, where he worked with Dr. Bob Zucker on the regulation of neurotransmitter release and Dr. John Rubenstein (UC San Francisco) on development of GABAergic neurons in basal ganglia. Dr. SheikhBahaei completed his doctoral studies in Neuroscience (2017) jointly under NIMH/NINDS – University College London (UCL) Graduate Partnership Program where he worked with Drs. Jeffrey Smith (NINDS) and Alexander Gourine (UCL). His graduate studies were on how astrocytic networks control activities of respiratory motor circuits within the brainstem. After short postdoctoral research at NINDS, Dr. SheikhBahaei became an Independent Research Scholar in 2019. In collaboration with the lab
These monkeys formed an unlikely friendship after Hurricane Maria wrecked their home
In the face of a natural disaster, one group of furry creatures used the opportunity to form new friendships.
After Hurricane Maria swept through Puerto Rico in 2017 and caused immense damage, researchers found rhesus macaques, a species of monkey living on Cayo Santiago became more sociable with each other, according to a study published in the journal Current Biology.
The monkeys live in a highly competitive society and can become aggressively protective over resources like food and water, said study author Camille Testard, doctoral candidate in neuroscience at the University of Pennsylvania’ Perelman School of Medicine.

Science Immunology, suggest only a single vaccine dose may be needed to produce a sufficient antibody response.
Researchers found that those who did not have COVID-19 called COVID naïve did not have a full immune response until after receiving their second vaccine dose, reinforcing the importance of completing the two recommended doses for achieving strong levels of immunity.
The study provides more insight on the underlying immunobiology of mRNA vaccines, which could help shape future vaccine strategies.
“These results are encouraging for both short- and long-term vaccine efficacy, and this adds to our understanding of the mRNA vaccine immune response through the analysis of memory B cells,” says senior author E. John Wherry, chair of the department of systems pharmacology and translational therapeutics at the University of Pennsylvania and director of the Penn Institute of Immunology in the Perelman School of Medicine.

Those who have had COVID-19 may only need one vaccine dose, a new study suggests People who have recovered from COVID-19 had a robust antibody response after the first mRNA vaccine dose, but a little immune benefit after the second dose, according to new research from the Penn Institute of Immunology.
