Hanspeter Pfister’s research in visual computing lies at the intersection of visualization, computer graphics, and computer vision and spans a wide range of topics, including biomedical image analysis and visualization, image and video analysis, interpretable machine learning, and visual analytics in data science. Pfister was recruited through our year 1 pilot project on machine-vision approaches to tissue analysis. He and his lab are developing machine learning methods for analyzing multi-dimensional tumor tissue images with the goal of more accurately assigning cell type and determining the distribution of tumor, stromal, and immune cells in cancers before and after treatment (Project 2).
Director, Breast Tumor Immunology Laboratory, Dana-Farber Cancer Institute
Assistant Professor, Harvard Medical School
Member CCSP Executive Committee
Jennifer Guerriero studies the role of tumor associated macrophages in promoting tumorigenesis and as a therapeutic target. Her research aims to understand the molecular and functional regulation of tumor macrophage phenotype and subsets, identify how tumor macrophages inhibit T cell function and limit the effectiveness of immunotherapy, and identify novel strategies to target macrophages therapeutically. Guerriero was recruited through outreach by the Systems Pharmacology Core and has brought new insight into macrophage biology to the CCSP, particularly in the context of breast cancer and immune therapy (Project 3).

Mohammed AlQuraishi works at the intersection between computer science, systems biology, and structural biology. He develops bespoke machine learning models that use biophysical insight to learn protein structure from primary sequence via differentiable algorithms, of which deep learning is a specific example. Biological applications include ab initio structure prediction, modeling signal transduction networks and protein-small molecule docking.
Director, Surgical Oncology Research Laboratories, Massachusetts General Hospital
Associate Professor, Harvard Medical School
Genevieve Boland is focused on the identification of tumor-intrinsic and immune-related mechanisms of response and resistance to immunotherapy and the identification of blood-based biomarkers of therapeutic response. Her laboratory is also defining and characterizing biomarkers of immune-related toxicities to develop new clinical targets and diagnostic tools.
