Gut metabolites: how the microbiota regulate host immunity and behavior in aging and after stroke

Dr. Lee studied mucosal immunology during his Ph.D. training in Dr. Hiroshi Kiyono’s laboratory at The University of Tokyo from 2013 to 2016. His primary focus was investigating how epithelial and immune cells in the intestines respond to inflammation in the context of inflammatory bowel disease. In 2016, he joined Dr. Louise McCullough’s laboratory in the Department of Neurology, McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth) as a postdoctoral research fellow. With the support of a Postdoctoral Fellowship and the Lawrence M. Brass Stroke Research Award from the American Heart Association (AHA) and the American Brain Foundation, Dr. Lee’s research explored how the microbiota-gut-brain axis alters neuroinflammation in aging and stroke models. In 2021, he won the President’s Excellence in Postdoctoral Research Award at UTHealth for his work. Dr. Lee was also recently awarded a Career Development Award from the AHA for his new studies interrogating the role of gut lymphocytes and their interactions with microglia in cerebral amyloid angiopathy and Alzheimer’s disease. Dr. Lee is currently an Assistant Professor in the Department of Neurology at McGovern Medical School, and his laboratory of neuro-mucosal immunology is exploring (1) neuro-immune interactions; (2) host-microbe interactions; and (3) inter-organ communication in aging and age-related cerebrovascular and neurodegenerative diseases. His laboratory aims to determine the mechanisms underlying brain-gut communication in diseases. This work will identify new therapeutic targets to manipulate the gut-brain axis using state-of-art techniques including metagenomics, metabolomics, flow cytometry, brain organoids, and single-cell RNA sequencing.

A distinct population of heterogeneously color tuned neurons in macaque visual cortex

Dr. Sunny Nigam obtained his undergraduate and master’s degree in Physics from India. To further pursue his scientific interests, he moved to the United States where he obtained his doctoral degree in Biophysics at Indiana University under the supervision of Dr. John Beggs. Dr. Nigam’s work focused on inferring network connectivity between hundreds of neurons using information theory and high-performance computing. His doctoral work led to the discovery of a sub-network of densely connected hub neurons (rich-club) in the micro-connectome of the cortex. In addition to his research, Dr. Nigam spends a significant portion of his time at Indiana University as an Assistant Instructor teaching physics to undergraduate students. To add to his scientific training in computational neuroscience, he joined Dr. Valentin Dragoi’s lab at the McGovern medical school at UTHealth. There he was able to obtain training in in-vivo electrophysiology in non-human primates to answer a diverse set of questions on how complex visual stimulus is encoded in populations of neurons in behaving macaques. Dr. Nigam’s future goal is to set up his own laboratory as an independent investigator to pursue pertinent questions related to brain function and mentor a diverse group of future scientists in the field of systems neuroscience.
