The Zaid Siddiqui Image-Guided Adaptive Therapy Lab
The Zaid Siddiqui - Image-Guided Adaptive Therapy Lab applies computational methods to test biomedical hypotheses on medical images. We use both mechanistic models and statistical methods (embeddings) to derive insights from both routine and novel image acquisition techniques.
Lab Projects
Some current projects include:
- Hydrodynamic modeling of pulmonary embolism and arteriovenous malformations and their response to therapy
- Genomic and anatomic predictors of volume change in brain tumors post-therapy
- Modeling cellular response and fitness to therapy using multi-parametric MRI
- Studying the biophysical effect of adaptive and/or novel radiotherapy delivery mechanisms
- Assessing performance and bias of artificial intelligence classification and generative systems
Our lab is open to collaboration with anyone seeking image analysis at any biomedical scale (live-cell imaging to multiparametric whole-body imaging).
