==Biography== Chatterjee was born in Kolkata, India, to parents Aditya Nath and Pranati Chatterjee. He attended Ballygunge Government High School and Saint Xavier's College. He received his bachelor's degree in statistics from the Indian Statistical Institute in 1993, and his master's in 1995.<ref name=":2">{{Cite web|title=Nilanjan Chatterjee Wins COPSS Awards|url=https://magazine.amstat.org/blog/2011/10/01/chatterjee-oct11/|access-date=2020-07-15|website=Amstat News|date=October 2011|language=en-US}}</ref> Chatterjee earned his PhD in Statistics from the University of Washington, Seattle in 1999.<ref name="NCI">{{cite web|title=Nilanjan Chatterjee, Ph.D.|url=http://dceg.cancer.gov/about/staff-directory/biographies/K-N/chatterjee-nilanjan|website=National Cancer Institute|date=January 1980}}</ref> His PhD thesis, titled "Semiparametric Inference Based on Estimating Equations in Regression Models for Two-Phase Outcome-Dependent Sampling," was advised by Norman Breslow and Jon A.

Chatterjee joined the National Cancer Institute (NCI) as a postdoctoral fellow in the biostatistics branch of the Division of Cancer Epidemiology and Genetics (DCEG) in 1999, and became a tenure-track investigator in 2001 and a senior investigator in 2004. He served as chief of the biostatistics branch from 2008 until 2015.<ref name=":2" /> He remains a Special Volunteer at the NCI.<ref>{{Cite web|date=1980-01-01|title=Nilanjan Chatterjee, Ph.D. - Special Volunteer, biographical sketch and research interests - National Cancer Institute|url=https://dceg.cancer.gov/about/staff-directory/chatterjee-nilanjan|access-date=2020-07-15|website=dceg.cancer.gov|language=en}}</ref>

==Research== Chatterjee is known for his work in quantitative genetics, cancer research, big data, statistical methodology, genomics, gene-environment interaction, genetic association and genome-wide association studies.

Chatterjee developed a model for predicting breast cancer risk that combines individual-level data on risk factors such as smoking and age with genetic variations associated with higher risk of breast cancer.<ref>{{Cite web|date=2016-05-26|title=Healthy lifestyle choices can help women overcome genetic breast cancer risk|url=https://hub.jhu.edu/2016/05/26/healthy-lifestyle-breast-cancer-risk/|access-date=2020-07-15|website=The Hub|language=en}}</ref> He led a large collaboration of experts from the Johns Hopkins School of Medicine, the Bloomberg School of Public Health, and the Whiting School of Engineering that used big data and machine learning to develop tools for autism risk prediction and intervention.<ref>{{Cite web|date=2018-06-11|title=30 interdisciplinary research teams receive Johns Hopkins Discovery Awards|url=https://hub.jhu.edu/2018/06/11/30-teams-receive-discovery-awards/|access-date=2020-07-15|website=The Hub|language=en}}</ref><ref>{{Cite web|title=Johns Hopkins Discovery Awards: 2018 Awardees|url=https://research.jhu.edu/major-initiatives/discovery-awards/2018-awardees/|website=Johns Hopkins Office of Research|date=11 June 2018}}</ref>

Chatterjee has participated in the Johns Hopkins Individualized Health Initiative (Hopkins inHealth), which aims to improve individual and population health outcomes through innovative collaborations among experts in biomedical and data science.<ref name=":1" /><ref>{{Cite web|title=Signature Initiatives|url=https://research.jhu.edu/major-initiatives/signature-initiatives/|website=Johns Hopkins Office of Research|date=30 March 2016}}</ref> Chatterjee's contributions to the initiative involved research on using genetic markers for risk prediction models as well as their applications to personalized medicine and public health interventions.<ref name=":1" />

Through his quantitative studies of gene-environment and gene-gene interactions, Chatterjee has also made fundamental contributions to theoretical and methodological approaches in epidemiology and biostatistics.<ref name=":1" /><ref name=":2" /> Using statistics from genome-wide association studies to appraise the number of DNA variations that contribute to different physical traits and diseases, Chatterjee and colleagues developed a method for estimating the number of individual samples needed in order to identify genetic bases of traits, such as height or body mass index (BMI), or diseases, such as diabetes or bipolar disorder.<ref>{{Cite journal|last1=Zhang|first1=Yan|last2=Qi|first2=Guanghao|last3=Park|first3=Ju-Hyun|last4=Chatterjee|first4=Nilanjan|title=Estimation of complex effect-size distributions using summary-level statistics from genome-wide association studies across 32 complex traits|url=https://www.biorxiv.org/content/biorxiv/early/2017/08/11/175406.full.pdf|journal=Nature Genetics|year=2018|language=en|volume=50|issue=9|pages=1318–1326|doi=10.1038/s41588-018-0193-x|pmid=30104760|s2cid=51979576|issn=1546-1718}}</ref> This method can be used for designing genetic studies and understanding genetic risk prediction.<ref>{{Cite web|first1=Robin |last=Scullin|date=2018-08-13|title=Understanding genetic architecture of different traits and diseases could lead to better-designed studies, researchers say|url=https://hub.jhu.edu/2018/08/13/genetics-and-disease/|access-date=2020-07-15|website=The Hub|language=en}}</ref>
