Associate Professor Aniruddha Chatterjee
Principal Investigator, Rutherford Discovery Fellow
Aniruddha is originally from Berhampore, West Bengal (India), where he completed his schooling. He moved to the southern part of India and completed a BSc (Osmania University, Hyderabad) and MSc degree (VIT University, Vellore) in Biotechnology with first class and distinction. Following this, Aniruddha came to the University of Otago in New Zealand in 2009, where he commenced his PhD. In his doctoral work, he mapped whole-genome scale DNA methylation patterns and variation in normal human neutrophil cells. Aniruddha played a leading role in performing the first reduced representation methylation sequencing in human neutrophils, melanoma, and the model organism zebrafish. He also heavily published in methodology development for DNA methylation and microRNA analysis. In 2017 he was awarded the prestigious Rutherford Discovery Fellowship from the Royal Society of New Zealand to establish this Epigenetics, Disease, and Phenotype Laboratory (EDP). Outside of work he enjoys dancing, acting, sports, travelling, and music.
Aniruddha welcomes enquiries about opportunities to study or work in the Chatterjee Laboratory.

Dr Euan Rodger
Co-Principal Investigator, Senior Research Fellow
After completing his PhD in the Department of Biochemistry at the University of Otago, Euan moved across campus to Pathology where he is now co-principal investigator in the Chatterjee laboratory. He is currently involved in projects using genomic/epigenomic methods in several different contexts, including: identification of novel candidate biomarkers and drug targets for colorectal, prostate and lung cancer; profiling of circulating tumour DNA to monitor disease burden in cancer patients; DNA methylation analysis of microdissected tumour regions and isolated cell subsets and mapping the methylome of patients with cancers to develop blood-based diagnostic tools. Outside the lab Euan enjoys spending time with his family, painting, gardening, and listening to music.

Dr Peter Stockwell
Scientific Officer
Peter's PhD from the Biochemistry Department was one of the earliest to concentrate on computational rather than laboratory bench work. Throughout his career he has collaborated with lab workers to resolve problems requiring computational solutions, often by programming for the computing resources of the time. Work has extended from the earliest times of DNA sequencing through to the present Next Generation Sequencing technologies. An extensive collaboration with Aniruddha led to development of DMAP (Differential Methylation Analysis Package), a set of tools which have been widely applied to other projects.

Sai Shyam Vasantharajan
Assistant Research Fellow
Sai is originally from Bangalore, India. He completed his Master’s in Biochemistry from India, and he came to New Zealand to pursue his dream of doing a PhD in cancer research. During his PhD, he worked on isolating circulating tumour cells from the blood of colorectal cancer patients. He completed his PhD in June 2024 and joined the laboratory as an Assistant Research Fellow. His research will focus on identifying biomarkers in circulating tumour DNA of lung cancer patients. In his free time, he enjoys listening to music, cooking, playing soccer and cricket, and any other outdoor sports. He also loves to watch standup comedy.

Maryam Yassi
PhD Student
Co-supervision with Associate Professor Matthew Parry.
Maryam received her Bachelor's degree in Computer Engineering - Software from Sajjad University, Mashhad, Iran, in 2008, and her Master's degree in Computer Engineering - Artificial Intelligence from Islamic Azad University, Science and Research Branch Tehran, Tehran, Iran, in 2013. After her graduation, she was employed as a bioinformatician to investigate the cell-free DNA methylation status of plasma and tissue samples in order to develop a DNA methylation test for early detection of colorectal cancer by liquid biopsy in the cancer genetic research laboratory, Reza Radiotherapy and Oncology Center, Iran. Her current research interests include computational cancer genomics, bioinformatics, machine learning, deep learning, and artificial intelligence. The goal of her PhD research is to find innovative statistical and computational solutions to problems in cancer diagnosis using cell-free DNA methylation sequencing data, which is emerging as a novel noninvasive cancer detection method.

Mark Ezegbogu
PhD Student
Mark completed his BSc (Hons) and MSc in Medical Laboratory Science (Clinical Chemistry) at the University of Benin, Nigeria. He was awarded the Commonwealth Scholarship in 2018 to pursue an MSc in Forensic Science at the University of Kent, UK. His interest in epigenetics led him to start a PhD in the Chatterjee lab where he aims to identify cell-free DNA (cfDNA) signatures to improve lung cancer screening. Outside of research, you will almost always find Mark playing chess or the acoustic guitar.

Atreyi Dutta
PhD Student
Atreyi completed her Integrated Master’s in Biotechnology in 2021 from St. Xavier’s College (Autonomous), Kolkata. She did her Master’s dissertation from the Department of Biochemistry, Indian Institute of Science (IISc), Bengaluru. After this she joined as an intern and subsequently as a Research Assistant in Tata Translational Cancer Research Centre (TTCRC) in Kolkata. During her time in TTCRC, she worked in the Minimal Residual Disease group wherein her project was focused on determining the residual leukemic cells in different stages of treatment in patients with Acute Lymphoblastic Leukemia. Her fascination towards epigenetics had taken a root during her college courses and her work with cancer patients piqued her interest in the field of oncology. In the Chatterjee lab, Atreyi wants to identify epigenetic biomarkers from cfDNA of prostate cancer patients to allow for a less invasive method for prostate cancer diagnosis. In her spare time, Atreyi loves reading books, listening to music, watching movies and hanging out with friends.
