Working alongside Professor Marc-Olivier Coppens and Dr. Matthew Chin, their research looks to develop novel, nature inspired 3D scaffolds as T-cell culturing environments. As a computational researcher, Lucy has designed various computational pipelines to create and analyze both the scaffolds being 3D printed and the experimental results from the wet lab.
Maria Caterina Rotiroti
Maria Caterina Rotiroti is a postdoctoral fellow in Dr. Robbie Majzner’s laboratory at Stanford University. Dr. Rotiroti developed her interest in cancer immunotherapy by joining the Fondazione Tettamanti in Monza, Italy as an undergraduate student. After graduating, she enrolled in a Ph.D. program in Molecular and Translational Medicine (University of Milano-Bicocca, Italy), continuing her research studies on developing CAR T cell therapies for treating acute myeloid leukemia. She is interested in developing innovative strategies to prevent tumor immune escape following adoptive transfer of CAR T cells.
Marshall Quinlen
Quinlen F. Marshall is a senior oncology research technician in the lab of John Maris, MD at the Children’s Hospital of Philadelphia and the University of Pennsylvania. His work focuses on engineering CAR T cells for pediatric solid tumors targeting intracellular proteins presented on MHC class I. His work has spanned the bench to bedside. Most notably, a CAR T cell product he helped develop is set to enter an early-phase clinical trial for high-risk neuroblastoma at the Children’s Hospital of Philadelphia in 2024. He is also interested in using insights from structural biology to inform immunotherapeutic development.
Matthew Chin
Dr. Chin is a Research Fellow advised by Prof. Marc-Olivier Coppens at the CNIE & Chemical Engineering, University College London (UCL). He is a bioengineer (Ph.D., UCL; BEng ACGI MSc DIC, Imperial College London) with experience in biomaterials, mechanobiology, microfluidics, mechatronic systems, and computational modelling. His current research focuses on designing and fabricating 3D cell culture platforms to study biophysical T cell interactions within structurally and mechanically complex microenvironments.
Nikolaos Sgourakis
My lab studies antigen processing, display, and recognition on class-I proteins of the Major Histocompatibility Complex. The human MHC-I (or, HLA) are the most polymorphic proteins in our genome, which necessitates the development of personalized approaches to address patient diversity in a therapeutic setting. We tackle this problem in two ways: To enhance processing and loading of MHC-I with antigens for display on the cell surface, we have engineered molecular chaperones that are tailored to different HLAs. To recognize specific MHC-I complexes by molecular therapeutics, we are developing peptide-centric receptors by blending protein engineering approaches with structural & in vitro characterization.
Sandeep Srivastava
Dr. Sandeep Kumar Srivastava, Ph.D., is the Cellular Therapy Laboratory Lead (CTL Lead, Process Development) at Cellular Therapy Laboratory, Centre for Cancer and Immunology Research, Children’s National Hospital, Washington DC. Dr. Srivastava involves several activities such as performing protocol development, process development studies, product validations, and cellular therapy product manufacturing to include novel cellular therapy products for FDA-approved investigational new cancer drug (IND) applications using current Good Manufacturing Practices (cGMP). Dr. Srivastava received his Ph.D. from the All India Institute of Medical Sciences, India.
Richa Kapoor
Richa Kapoor, Ph.D. is an immune-oncology scientist working in the laboratory of John M Maris at the Children's Hospital of Philadelphia. Richa pursued her post-doctoral training in immunology, oncology, and cell & molecular biology at the University of Pennsylvania. She is a passionate researcher engaged in identification of novel targets and developing immunotherapies to treat solid tumors.
Anna Eastman
Anna is a postdoctoral researcher in the laboratory of Dr. Irving Weissman at Stanford University. A stem cell biologist by training, she is investigating certain forms of pediatric epilepsy as potential models of premalignancy in the brain. Using primary human brain tissue, this research seeks to address gaps in our understanding of early events in brain oncogenesis, including analysis of molecular interactions between glial progenitors and their microenvironment that may favor the expansion of premalignant clones.
Erin Runbeck
Erin is a research scientist in the laboratory of Dr. John Maris at the Children’s Hospital of Philadelphia. Her background is in cancer immunotherapy, specifically for solid tumors. Within the Maris lab, her focus has been developing and testing engineered T cells directed toward novel cancer markers. Her work particularly studies the targeting of cancer-associated proteins that reside within the cell, but are presented on the surface through natural mechanism of immune surveillance.
Alastair Hotblack
Alastair Hotblack is an immunologist who works on how engineered T cells interact with the tumor microenvironment. He completed his Ph.D. at UCL in 2016, investigating the tumor interaction between engineered T cells and antigen-presenting cells. He then joined the UCL CAR-T cell program as a post-doc, where he established multiple mouse models of CAR-T cell therapies for different brain and other solid tumors. His work will utilize ‘next-generation’ CAR T cells to overcome the hurdles of the suppressive tumor microenvironment in pediatric solid tumors.
Ashley Geiger
I originally completed my Master’s in Animal Sciences focusing on muscle biology before I transitioned to cancer and immunology research. I started working at Children’s National in 2018 after graduate school and have been working under the guidance of Drs. Russell Cruz and Catherine Bollard. My work focuses on generating tumor associated antigen (TAA)-T Cells from healthy donors to combat various brain tumors. Along with generating TAA-T Cells, we are also interested in identifying new and novel tumor targets found in pediatric cancers.

At CETI lab, her research focused on developing novel immunotherapies to target tumor-associated antigens and manage immune suppressive tumor microenvironment in pediatric solid tumor malignancies.
Stephanie Gomez
Stephanie is a postdoctoral research fellow in the laboratory of Dr. Catherine Bollard at the Children’s National Hospital. She earned her PhD at the George Washington University in fall 2023, with her dissertation research focused on immunotherapy, epigenetic therapy, and the tumor microenvironment, in the context of ovarian cancer. Within the Bollard Lab, her focus has been two-fold: 1) assessing immune correlates for a phase 1 clinical trial assessing safety and efficacy of TAA-T cells for the treatment of pediatric brain tumors, and 2) engineering CAR T cells to combat the immunosuppressive tumor microenvironment of pediatric solid tumors, specifically focusing on sarcoma and neuroblastoma.
