John Iafrate, MD, PhD

Deputy Chair of Pathology for Academic Affairs

Former Director of the Center for Integrated Diagnostics (CID)

Pathologist in Pathology, Massachusetts General Hospital

Dr. Iafrate received his MD, PhD degrees from the State University of New York at Stony Brook in 2000, and was trained in anatomic and molecular genetic pathology at Brigham and Women's Hospital. He joined the Massachusetts General Hospital staff in 2005. His post-doctoral work involved the discovery and description of a novel source of human genetic diversity, termed "Copy Number Variation" (CNV). His work, using genome-wide array comparative genomic hybridization (CGH) assays, contributed significantly to clinically differentiating pathogenic CNVs from CNVs that are less likely to contribute to an affected individual's clinical presentation.

He established the Center for Integrated Diagnostics, a cancer diagnostics lab focusing on genetic fingerprints that help guide novel, targeted therapies. In 2008, his lab launched “SNaPshot”, the first multiplexed genotyping assay in genotyping primary and recurrent tumors and later implemented next generation sequencing (NGS) technologies including the development of Anchored Multiplexed PCR (AMP), now a widely-used sequencing platform. His research is focused on lung and brain tumors, and he has been closely involved in the clinical development of crizotinib and companion diagnostics in ALK-positive lung cancers. His lab is now focused on developing assays for detecting tumor DNA in circulation (ctDNA) and launched one of the first clinical ctDNA assays for lung and breast cancer in 2018.

Anna (Chegzhou) Gao, PhD

Anna is a Senior Research Scientist with expertise in Molecular and Cellular Biology. Currently, she is working on High Content Imaging Assay development and optimization. In her free time, she likes to read, watch movies, and enjoy outdoor activities with her family.

Diane Yang, PhD

Postdoctoral Fellow

Diane is a postdoctoral fellow interested in developing new small molecules targeting oncogenic drivers of cancer. Her current project is identifying novel therapeutic targets for ALK+ small-cell lung cancer using molecular biology and proteomic analysis. She also studies the mechanism of action of small molecules with cell biology and gene editing.

Diane grew up in Taiwan and received her Ph.D. in Molecular and Cellular Biology from Baylor College of Medicine, where she studied stem cell differentiation for regenerative medicine. In her free time, she enjoys cooking and researching recipes, petting soft and fluffy cats, and traveling.

Annie Li, MD

Postdoctoral Fellow

Annie is currently investigating the immune landscape of adenoid cystic carcinomas, a rare cancer of the head and neck region using a multiplex immunofluorescence platform. She is also investigating utilizing customized liquid biopsy assays in rare sarcomas as a novel diagnostic tool.

Annie grew up in Germany and graduated from Medical School at the University of Heidelberg. In her free time, she enjoys spending time with friends, trying new restaurants, watching movies and traveling.

Stefan Kaluziak, PhD

Postdoctoral Fellow

Liz Codd

Bioinformatics Specialist I

Liz Codd earned her Master of Science in Bioinformatics from Northeastern University in December 2022. She first started working in the Iafrate Lab as an intern during her graduate studies, then joined the lab as a Bioinformatics Specialist this past January. She works on data analysis and pipeline development for a variety of exciting transcriptomic and epigenomic projects. Her current research focus is alternative transcription and epigenomic regulation in Triple Negative Breast Cancer and Adenoid Cystic Carcinoma

Before entering the field of bioinformatics, Liz received a Bachelor of Mathematics from Rhode Island College and a Master of Music in Violin Performance from Park University. She worked as a freelance violinist in Kansas City for several years where she performed with orchestras including the Kansas City Symphony and pop stars such as 2Cellos, recorded three albums with platinum rapper Tech N9ne, and played milongas with a five-piece tango band. Liz Codd is originally from Providence, RI and currently resides in Worcester, MA with her fiancé Sean and their black cat Jack.

Dawn Mitchell

Bioinformatics Graduate Student Intern

Dawn is a Bioinformatics Master's student at Northeastern University and has been working with Stefan on image analysis pipelines since Spring 2023. During her time in the lab, Dawn has built a live-cell imaging analysis pipeline and is currently investigating pipelines for processing multiplex immunofluorescence imaging data.

Dawn holds a B.S. in Geophysical Sciences from the University of Chicago and an M.S. in Computer Science from Brandeis University. In her free time, she enjoys practicing piano, playing video games, and going for walks with her partner.

Edwin Zhang

Research Technician I

Edwin graduated from Brandeis University in 2019 with a B.A in Biology and Neuroscience. He is currently working with Diane on her project identifying novel therapeutic targets for ALK positive non-small cell lung cancer. He works on screening new compounds, running Western Blots, and producing/purifying recombinant protein. In his free time, he enjoys reading, learning how to cook new dishes and eating new dishes. A fun fact is that he has never had coffee in his life!

Bianca Gonda

Research Technician I

Bianca received her B.A. in Biology from New York University. Currently, she is working on immunologically profiling tumors using multiplex immunofluorescence and immunohistochemistry. She is currently working with Annie on profiling a variety of different tumor types. Outside of work, Bianca enjoys traveling, spending time with her friends, family, and pets, and exploring the city. 

Thuc Dzu

Research Technician I

Thuc graduated from Johns Hopkins University with a B.A. in Biophysics. He works with Stefan and Annie on projects that include the development of diagnostic NGS assays and monitoring of tumor growth using biomarkers secreted by tumor cells in the blood. In his free time, he enjoys rock climbing, reading, and spending time with friends.
