Postdoctoral fellow

Dr. Frolinger is trained in behavioral neuroscience with educational and research background ranging from physiological sciences to behavioral sciences, psychopharmacology and neuroscience.  Her main research area during the last few years is novel animal models for affective and neurodegenerative disorders. In that context Dr. Frolinger was successful in developing and using appropriate animal models to link basic physiological and molecular findings in this field to behavioral outcomes and her work is a part in collaborative efforts that are exemplary for biological psychiatry research. Dr. Frolinger will join the lab with emphasis on studying gene expression and optogenetics in animal models of stress.

Maria Sebastian Valverde, Ph.D 

Postdoctoral Fellow

Dr. Sebastian obtained her PhD in Biochemistry and Molecular Biology in 2018 from the University of Zaragoza in Spain. Her studies were focused on the biophysical and structural characterization of bacterial proteins with high potentiality as antimicrobial targets. Additionally, Dr. Sebastian acquired extensive experience in the use of High Throughput Screening techniques for the identification and characterization of new drugs. In the Pasinetti lab, Dr. Sebastian is interested in understanding the molecular mechanisms that link neuroinflammation and depression, as well as in the development of new compounds that inhibit neuroinflammation as a potential treatment for different neuronal disorders.

Chad Smith, Ph.D.

Postdoctoral Fellow

Dr. Smith is trained in molecular biology and received his Ph.D. from the University of Texas at Dallas in 2015.  His field of research was to investigate the role of molecular chaperones such as heat shock proteins in neurodegenerative diseases such as Alzheimer’s and Huntington’s Disease, and their potential to suppress proteinopathic stress.  He is particularly interested in how early synaptic deficiencies modulate memory and cognitive impairments.  Dr. Smith works to establish optogenetic models to study how diverse polyphenols alter gene expression, signaling pathways, and synaptic plasticity involved in physiological resilience against stress.

Susan Westfall, Ph.D

Postdoctoral Fellow

Dr. Westfall is an expert in gut-brain-axis research with extensive experience studying the interaction of the gut microbiota with plant-derived prebiotics and their synergistic effect on neurological disorders. At Mount Sinai, Dr. Westfall is continuing this line of research using cutting-edge technology to develop novel synbiotic formulations to maximize the production of grape-derived polyphenols towards the promotion of cognitive resilience against neuropsychiatric disorders. Before coming to Mount Sinai, Dr. Westfall completed her PhD in Biomedical Engineering from McGill University in 2018 where her major contribution was identifying a unique synbiotic formulation that promoted longevity and prevented the onset and progress of Alzheimer’s disease in Drosophila melanogaster. Dr. Westfall also completed her BSc in Biochemistry and MSc in Neuroscience from McGill University giving her a diverse array of skillsets.

Research Associate

Mr. Brathwaite graduated from Columbia University in May 2014 with a Bachelor’s in Chemistry. He is currently pursuing a Masters of Science/Masters of Public Health at Boston University. His ultimate goal is to be a physician-scientist focusing on neurological conditions. Mr. Brathwaite has been trained in the characterization of novel brain bioavailable phenolic metabolites from complex botanical supplement mixture from in vitro studies under the tutelage of Dr. Ho.  Following the identification and characterization of these novel metabolites, he was trained in testing the molecular mechanisms using optogenetics techniques to visualize and interpret different molecular pathways in brain regions associated with learning and memory function.

Umar Iqbal

Research Associate

Mr. Iqbal graduated from McGill University in May 2018 with a Master’s degree in Biomedical Engineering. During his Master’s degree, he developed a novel microencapsulated probiotic blend and studied its potential as a treatment for metabolic syndrome. He also investigated the effect that his designed treatment would have on the gut microbiota, and how that could impact factors of metabolic syndrome. He is currently working with Dr. Frolinger and focusing on the effects of dietary botanicals on promotion of cognitive resilience to stress-induced depression through suppression of neuroinflammatory mechanisms. Mr. Iqbal also holds a Bachelor’s degree in Chemical Engineering which he obtained from McGill University.
