Jack Humphrey, PhD
Principal Investigator 

Jack obtained his Ph.D. in Clinical Neuroscience from University College London, after spending time as a visiting researcher at Stanford University and as a computational scientist at Inivata Ltd, a Cambridge-based biotech startup. He joined the lab of Towfique Raj at Mount Sinai as a postdoctoral fellow in 2019, and was promoted to Instructor in 2021. In his spare time he goes rock climbing and plays the bass. Read his CV.

Alice Maria Giani, PhD
Postdoctoral Fellow (co-mentored with Dr Towfique Raj)

Alice is a physicist by training who transitioned to study Neuroscience in her Master’s studies at the University of Milano-Bicocca working on the excitation-inhibition balance in neural networks. During her PhD in Molecular and Cellular Biology, she investigated the molecular mechanisms underpinning neurodevelopmental disorders and human-specific traits of brain development using induced pluripotent stem cells (iPSCs) and functional genomics approaches, working at the University of Milan and Yale University under the supervision of Dr. Nenad Sestan. After her PhD, she joined Dr. Shuibing Chen's lab at Weill Cornell Medicine to develop a barcoded human iPSC library and investigate the risk loci associated with Zika virus and other viral infections in neurons. Then, she joined Dr. Li Gan’s lab at Weill Cornell Medicine to investigate modifiers of tau aggregation and propagation, a key hallmark of broad class of neurodegenerative disorders known as tauopathies, such as Alzheimer’s disease (AD) and Frontotemporal Dementia (FTD). In the Humphrey lab and Raj lab she is currently exploring the role of gene expression in the neurodegenerative disorders including Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD), and Alzheimer's Disease (AD) using bioinformatics and machine learning approaches.

Alexander Chung
MD/PhD student (starting Summer 2025)

Alexander is an MD/PhD student who graduated from Cornell University. For his senior honors thesis, he researched the role of olfactory sensory neuron-derived extracellular vesicles in peripheral nerve regeneration in the lab of Dr. David Lin. After graduation, he worked in the lab of Dr. Mark Albers at Massachusetts General Hospital where he studied type I interferon neuroinflammation in the context of Alzheimer's Disease and ALS. He is currently interested in studying the genetics of immune cells in neurodegenerative diseases.

Brooke Friedman
PhD student (starting Summer 2025)

Brooke is a neuroscience Ph.D. student at Mount Sinai who is originally from Santa Clarita, California. She graduated magna cum laude from the University of Notre Dame in May 2024, where she studied neuroscience, linguistics, and global engagement. In her free time, she enjoys doing aerial silks and running through Central Park

Faith Singh
Master's student

Faith graduated from Hunter College with a Bachelors’ degree in biological sciences with a concentration of neurobiology. Her previous experience was as a clinical research coordinator at Lenox Hill Hospital Department of Neurosurgery. She is currently a Master’s student in Biomedical Sciences at Icahn School of Medicine at Mount Sinai.
