I am currently a data scientist in the department of predictive analytics and assistant professor of anesthesiology and critical care medicine at Johns Hopkins All Children's Hospital. I was previously a postdoctoral fellow at NASA supporting the Biological and Physical Sciences division, and prior to that I received my Ph.D. in chemical engineering and my M.S. in applied math and statistics from Johns Hopkins University.

My research interests include deep learning, generative models, manifold learning, dynamical systems, and biological systems. My work often involves the use of machine learning and data driven models to improve patient outcomes in clinical settings, but I also enjoy researching in my free time at the intersection of data science, chemical engineering, and dynamical systems.

Outside of academia and research, I enjoy playing soccer, lifting weights, playing chess, and collecting rare books.

Experience

July 2025 – Present

Data Scientist

Johns Hopkins All Children's Hospital, St. Petersburg, FL

Working on machine learning applications to anesthesia and predictive analytics.

Contributed (so far) to six currently pending publications and presentations. Check back here or at my Google Scholar page once they are accepted!

July 2024 – July 2025

NASA Postdoctoral Program Fellow

Marshall Space Flight Center, Huntsville, AL

Supported the biological and physical sciences division as well as the materials and processes division, primarily focusing on computational modeling and data science methods.

Developed machine learning models to predict properties of specific materials and generate alloy compositions consistent with prescribed microscopic properties and developed code to simulate aluminum alloys undergoing welding and validated the produced data experimentally.

June 2022 – June 2023

Visiting Data Scientist

Sandia National Labs, Livermore, CA

Researched the use of dimensionality reduction methods to produce reduced-order surrogate models for microstructure evolution in alloys and composite materials.

Developed deep learning architectures and numerical methods for reduced-order modeling and uncertainty quantification of systems of interest to the DOE.
