This project focuses on the use of machine learning techniques in external radiotherapy for cancer treatment planning.
Stochastic frontier analysis is a parametric approach used in econometrics and appropriated for medical physics. Using a retrospective bank of treated patients it will be possible to predict the optimal dose of radiation for tumor and healthy organs.
This method is applied to multiple cancer treatment sites which emerge new challenge in the context of prediction, and data processing.

The characterization of Drug-Drug interactions (DDIs) is crucial for planning therapies and drugs
co-administration. While considerable efforts are spent in labor-intensive in vivo experiments and time-consuming clinical trials, understanding the pharmacological implications and adverse side-effects for some drug combinations is challenging. The joint impact of the majority of combinations remains undetected until therapies are prescribed to patients. This raises the need for computational tools predicting DDIs in order to reduce experimental costs and exhaustively characterize all drug combination effects before therapy recommendations. 
Previous attempts to build such tools focused on pharmacodynamic and pharmacokinetic interactions and used features that are difficult to access in the early stages of R&D. 
In this work, we propose to use data about the drugs and their targets (pathways, biomarkers, gene expressions, etc) that are available at the beginning of each drug R&D campaign. Our hypothesis is that high-level deep learning features extracted from those data will improve DDI characterization. Therefore, our models will be trained to output the pharmacological effects of DDIs as well as underlying molecular and biological pathway interactions. 
Creating such a comprehensive toolkit will help to reduce risks in polypharmacy therapies.
 

The research project is focused on the synthesis of medical images using deep learning, towards better artifact correction and the avoidance of unnecessary medical procedures.

The neural networks designed in this project have a flexible architecture enabling the image synthesis from only an heterogeneous subset of input modalities. The images are synthesized in pathological situations, such as Alzheimer's disease and brain cancers.

This project is centered on an examination of the process of preparing a patient-centered media and social media strategy that provides patients with useful information about the Opal patient portal and how they can make the most of it.

This project is part of the effort to prepare Opal for use by patients, providing them with self-management resources such as questionnaires and educational materials.

The primary objective of this research project is to detect cancer pain at an early stage by analyzing patients’ medical images. 
Development of an algorithm to do this can be achieved by combining two computer science techniques: one that allows us to gather information about pain from medical notes, and one that extracts information from medical images. We will use the first technique in a computer program that will extract and quantify pain intensity recorded in patients' medical notes. 
The second technique will be employed in another program that will analyze radiographic images of cancer patients’ to extract information about their bone metastases (such as tumor volume, and shape). Then, we will implement advanced statistical and mathematical techniques to model the relationship between identified tumor features and extracted pain intensities. 
Finally, to validate our model, we will use pain scores that are directly collected from thousands of future cancer patients via a mobile app that has been developed in our group (opalmedapps.com).
 

This research project aims to examine the mutational signature of ionizing radiation using single-cell sequencing techniques.

The project is using human lymphoblastoid cells donated by the Ashkenazi trio that have a well characterized genome. The cells are irradiated and sequenced to determine the mutations that are induced as a result of the exposure to the ionizing radiation.

Through biostatistical analysis of the human genomic data thus obtained, we will be able to identify the mutational signature of ionizing radiation.
