Dr. Jeff Goldsmith

Biography

Jeff Goldsmith is an Associate Professor of Biostatistics at the Mailman School of Public Health at Columbia University and serves as the Associate Director at the Data Science Institute. He received his PhD in Biostatistics from Johns Hopkins University in 2012. His work focuses on advancing state-of-the-art functional data analysis and developing methods for understanding patterns in large, complex datasets related to neuroscience and physical activity monitoring. Collaborating closely with clinicians and neuroscientists, his research aims to improve the understanding of skilled movements, particularly in stroke patients. Goldsmith's studies include experiments that record the fingertip positions of patients during reaching movements, leading to insights into the quality of movement post-stroke. Additionally, he has proposed innovative methods applicable to wearable device research, with a focus on accelerometers that capture minute-by-minute activity data over extended periods. His research encompasses regression approaches for activity trajectories and techniques for interpretable dimension reduction, which help align critical behavioral patterns such as sleep cycles and activity dips.
