Speaker Biographies

Melissa Davis
Melissa B. Davis, PhD

Melissa B. Davis, PhD, is an Assistant Professor (Interim) of the Department of Surgery and Scientific Director of the International Center for the Study of Breast Cancer Subtypes at Weill Cornell Medicine in New York City. She holds adjunct faculty appointments in the Department of Genetics at the University of Georgia in Athens and in the Department of Public Health Sciences at Henry Ford Health System in Detroit. Davis received her PhD in Molecular Genetics at the University of Georgia and postdoctoral training at Yale School of Medicine and the University of Chicago, where she completed groundbreaking genomics work related to steroid hormone functions during development. At the University of Chicago she also trained at the Center for Interdisciplinary Health Disparities Research, where she began her current research program: To identify biological mechanisms of racial disparities in cancer risk and clinical outcomes of cancer diagnoses. The Davis Lab has produced findings that have proven that unique genetic signatures in both breast and prostate tumors of African and African American patients are enriched for mechanisms that correlate with aggressive tumor progression, which generate novel opportunities for precision medicine applications in minority populations. She will present findings emerging from her breast cancer research, where she has identified that an African ancestry allele, and the recently discovered tumor expression, of a gene named DARC (ACKR1) are linked to the tumor-specific immune/inflammatory response. She has utilized Imaging Mass Cytometry™ (IMC) to characterize spatial distinctions among ethnically diverse patient groups.

Daniela Quail
Daniela F. Quail, PhD

Daniela F. Quail, PhD, is Assistant Professor at the Rosalind and Morris Goodman Cancer Research Centre and the Departments of Physiology and Experimental Medicine at McGill University in Montreal. She earned her PhD from the University of Western Ontario. Her doctoral research focused on the role of embryonic proteins on microenvironmental regulation of cancer stemness, invasion and metastasis. She completed her postdoctoral training at Memorial Sloan Kettering Cancer Center in New York. Her postdoctoral research focused on how the microenvironment impacts cancer progression and prognosis, with particular interest in the immune compartment. She contributed to a body of research characterizing the effects of the innate immune system in cancer, including the role of macrophages in brain tumors and neutrophils in breast cancer metastasis.

Since opening her lab at McGill, Quail served as Director of the Single Cell and Imaging Mass Cytometry Platform, where she developed multiplex imaging protocols to comprehensively immunophenotype the tumor microenvironment of lung and brain tumors. She was the Early Career Representative for the American Association for Cancer Research Tumor Microenvironment Working Group and currently holds a Tier II Canada Research Chair in the Tumor Microenvironment (2018–2023). The Quail lab studies cancer immunology through three major themes, including (1) the impact of chronic inflammatory conditions such as obesity on cancer progression and immunotherapy; (2) the role of diet and energy balance in shaping the immunological response to cancer; and (3) tissue-specific influences of the tumor microenvironment. By addressing these research gaps, her team hopes to contribute to improving and discovering new tools and therapies in immuno-oncology.

Marieke E. Ijsselsteijn
Marieke Ijsselsteijn

Marieke Ijsselsteijn is a researcher at the Leiden University Medical Center (LUMC), where she is set to obtain her PhD in the coming months. For the past 5 years, she has been working in the Noel de Miranda group, which focuses on neoantigen-targeted therapies, deep immunophenotyping of colorectal cancer and the search for immune cell subsets with antitumor activity. Ijsselsteijn has been implementing and improving deep immunophenotyping technologies such as multispectral immunofluorescence microscopy and Imaging Mass Cytometry. She has developed a ready-to-use 40-marker IMC panel for FFPE tissue, which allows the characterization of the tumor immune microenvironment, as well as an optimized workflow for maximum antibody performance. Furthermore, in collaboration with the Department of Radiology at the LUMC, she investigated the effects of signal variability between samples on IMC analysis and phenotype identification. Using publicly available tools, the team created a workflow for the normalization of IMC data by semi-automated background removal, directly applicable to previously obtained datasets. Aided by these tools, the De Miranda Lab collaborates with many research groups within and outside the LUMC to advance understanding of the spatial tissue microenvironment.

Vito Zanotelli, PhD
Vito Zanotelli, PhD

Vito Zanotelli found his passion to gather biological insights through large-scale quantitative experiments combined with statistics and machine learning during his BSc and MSc studies in Systems Biology at ETH Zurich. There he had the chance to work on cutting-edge metabolomics, proteomics and high-throughput imaging projects.

In search of a PhD program, he interviewed in the lab of Bernd Bodenmiller, PhD, at the University of Zurich. He was immediately fascinated by the (at the time) prototype technology called Imaging Mass Cytometry™, which enables acquisition of spatially resolved highly multiplexed measurements at cellular resolution.

During his PhD studies used this technology to study the origins of spatial single-cell heterogeneity, requiring the development of both computational and experimental tools to help to analyze and utilize this novel technology better. Apart from his main project on trying to understand spatial signaling in 3D spheroids, this expertise enabled him to contribute to more than a dozen papers in the field of mass cytometry. During this work, he also authored and contributed to multiple open source projects.

After his PhD, he joined D ONE in 2021 as a Data Analytics Consultant, enabling businesses of all kinds to better understand and utilize their data.
