Ananya Pradhan
Affiliate, Radiation Oncology - Radiation Biology
BioMy research sits at the intersection of deep learning, computational analysis, and understanding high-dimensional biological data to create a positive impact for patients. I am deeply fascinated by computer science and have experience working with generative networks and deep neural networks.
Currently, I am working with Dr. Seraphina Shi in the Esfahani Lab. My research focuses on analyzing epigenetic features of cfDNA fragments to develop deep learning architectures for early lung cancer detection. My prior independent research involved using variational auto-encoders and optical coherence tomography data to detect Alzheimer's disease at an early stage.
Outside of research, I enjoy student leadership and debate, and I’m always happy to have great conversations. I also love movies and spending time in nature. If any of these topics interest you, feel free to reach out! -

Manu Prakash
Associate Professor of Bioengineering, Senior Fellow at the Woods Institute for the Environment and Associate Professor, by courtesy, of Oceans
BioWe use interdisciplinary approaches including theory and experiments to understand how computation is embodied in biological matter. Examples include cognition in single cell protists and morphological computing in animals with no neurons and origins of complex behavior in multi-cellular systems. Broadly, we invent new tools for studying non-model organisms with significant focus on life in the ocean - addressing fundamental questions such as how do cells sense pressure or gravity? Finally, we are dedicated towards inventing and distributing “frugal science” tools to democratize access to science (previous inventions used worldwide: Foldscope, Abuzz), diagnostics of deadly diseases like malaria and convening global citizen science communities to tackle planetary scale environmental challenges such as mosquito surveillance or plankton surveillance by citizen sailors mapping the ocean in the age of Anthropocene.

Prince Allawadhi
Postdoctoral Scholar, Gastroenterology, Hepatology, and Nutrition
BioMy research focuses on immune-stromal crosstalk in pancreatic diseases, with an emphasis on how myofibroblasts and macrophages drive inflammation, fibrosis, and multi-organ dysfunction. By integrating patient-derived organoids, zebrafish models, and multi-omics, I aim to unravel the cellular and molecular mechanisms underlying pancreatic injury and repair. I am developing cutting-edge zebrafish models of exocrine pancreas disorders to uncover novel immuno-fibrotic pathways and accelerate the identification of translational targets for early diagnosis and therapeutic intervention.

John R. Pringle
Professor of Genetics, Emeritus
Current Research and Scholarly InterestsMuch of our research exploits the power of yeast as an experimentally tractable model eukaryote to investigate fundamental problems in cell and developmental biology such as the mechanisms of cell polarization and cytokinesis. In another project, we are developing the small sea anemone Aiptasia as a model system for study of the molecular and cellular biology of dinoflagellate-cnidarian symbiosis, which is critical for the survival of most corals but still very poorly understood.
